This application claims the benefit of US Provisional Patent Application Ser. No. 60 / 595,408
filed Jun. 30, 2005 and US Provisional Patent Application Ser. No. 60 / 643,468 filed on Jan. 13,
2005. , And the benefit of US Utility Patent No. 11 / 163,179, filed October 7, 2005.
The present invention relates generally to a method and apparatus for using environmental
sound for therapeutic effects, and more particularly to a method and apparatus for duplicating
environmental sound space.
There are various recording methods and devices and reproduction systems that reproduce the
way of sound in a given space in a space different from the given space, and in the different
space, a recording and reproduction system The way you hear the sound is reproduced.
For example, the sound experience when listening to a full orchestra in the open Amphitheater is
different from listening to the same orchestra in a concert hall, which listens to the same
orchestra in a large convention hall or recording studio It is different from that.
The way of hearing the sound at each place differs depending on the size and the material of the
surrounding structure.
The difference in the way the sound is heard is because the echo, absorption, etc. are different.
Thus, the sound coming out of the orchestra will differ in quality and fidelity to the listener
depending on how the sound in the area is heard. If the sound from the orchestra playing at any
place is recorded and played back by a standard recording-generation system, the sound of the
music that the listener receives at the time of playback is the way the sound of that place is heard
Not reproduce. Put another way, the acoustic experience of the listener during playback does not
reproduce the acoustic experience when the listener is listening live at the original location.
Some listeners prefer to listen to the rock band at the Amphitheater location and listen to the full
orchestra at the concert hall. A playback system that reproduces the dynamics of the sound of a
given type of location, designed as a method and system for recording and playback that allows
the listener to make choices when listening to the recorded music It has been. Several recording
and playback methods have attempted to reproduce the sound of famous places such as Carnegie
In addition, there are various recording methods and systems that produce various therapeutic or
soothing effects using various music tracks that may be combined with natural sounds or
onomatopoeia such as ocean waves. However, none of the above methods and systems have
overlapped and / or enhanced a given environmental sound space and reproduced in another
reproduced sound space to produce a therapeutic effect.

643,468 US Utility Patent No. 11 / 163,179
The present invention provides a method and apparatus for recording and playing back natural
sounds and / or natural sounds with improved sound quality for capturing and playing, and
separates the environmental sound space in such a way as to produce a therapeutic effect. To
reproduce in the acoustic space of
The method and apparatus record a natural sound with a adapted microphone array, record a
signal with a high resolution recording device to form an acoustic bed, and reproduce the
original acoustic space. Play recordings with a playback system that adjusts the playback space
to gain experience. The method and apparatus are used to generate or overlay an environmental
acoustic space for environmental therapy to give the patient the feeling of being in the original
space where the environmental sound was recorded.
The environmental therapy of the present invention comprises a combination of natural sounds.
This may be, for example, a 200 foot by 200 foot algorithm in one embodiment, which is
combined with the music portion from the sound event to produce a predetermined emotional
treatment effect. Produces The present invention implements the concept of psychoacoustics that
their ears tell us where a person is. There are various elements that are important to this method
of calming patients and their carers by distracting with believable phenomena, including noise
floor, time shifts, and distance algorithms / space recognition.
Typically, in most of our everyday world, we are surrounded by a certain amount of
environmental noise. However, sometimes the sound of the normal pattern that surrounds us will
cause sudden high transient spikes, disrupting us. This is sometimes referred to as startle sounds.
The low sound of a consistent boon or drone can provide comfort as being in a satisfactory state.
The present invention is a method of generating a natural sound drone that masks transient
noise, including systematic overlays. This is new compared to typical acoustic masking
A typical surround playback system includes a set of five satellite speakers and a subwoofer, and
a playback unit that provides power to the speakers and reads DVD media. These types of
systems have proven to be very simple and can quickly display the program material of the
present invention. This makes it clear that the home theater system can be improved in a project
encompassing the full concept of an environmental therapy system. This concept is neither a
home entertainment system, nor a standard surround sound recording / playback system, nor a
scheme or digital signal processing system for reproducing the sound of a particular location.
Standard surround sound systems include front left and right channels and center channels, rear
left and right channels and subwoofers. The three front channels provide the main part of the
part of acoustics, and the three front playback speakers are typically positioned in front of the
listener. Subwoofers are typically dedicated to low frequency sound, and the speakers of the
playback system are usually centered in the playback area or playback room. The left and right
rear channels usually provide a secondary part of the acoustics dynamics, providing sound
reflection and delay effects. These speakers are usually positioned behind the listener.
In contrast, the present invention provides a media playback system centered on the basis of
environmental therapy and embodies the inventive concept by providing a novel recording and
playback method. Environmental sound is captured by four independent multidirectional
microphones. These microphones are connected to four separate recording channels and
arranged in a 60 foot 96 foot (200 foot by 200 foot) sound recording array. A four channel
playback system plays four independent recording channels on four corresponding playback
channels and speakers. Independent, multi-directional arranged in a 60.96m x 60.96m (200 ft x
200 ft) recording array to reproduce the acoustic space of a 60.96 m x 60.96 m (200 ft x 200 ft)
recording area The acoustic delay and other acoustic dynamics formed and incorporated by the
microphone are reproduced in four reproduction channels. The sounds or temporal delays
realized during recording by the independent microphones are adapted and reproduced by the
reproduction channel and the speakers. In addition, the playback system may optionally include
subwoofer channels. An environmental therapy system (ATS) and its components can function in
the recovery room and treatment environment of a hospital. However, the present invention is a
method of recording and reproducing, which is not specifically related to the electronic
components used to implement the method. The dimensions of the recording array may be
varied to form an optional acoustic space.
The invention eliminates the user operating the machine, but makes the recovery room of a
typical hospital louder, the world or the acoustics of the audible environment far from the noise
and beeps generated by all medical devices. Provide a device that forms a space. The playback
system can be designed to be very transparent, can not focus on the patient listening to the
recorded sound, convinces the patient to be somewhere outside the hospital room, Prepare for
recovery or enter the operating room. Thus, one objective is to provide a physically separate, low
visual, hidden, unobtrusive device.
The system of the present invention provides a user interface that is easy to operate and not
visually disturbed. Along with the playback device, the speaker that is the sound source of the
environment program is also hidden, and the patient is not listening to the speaker, but instead it
is as if the original recording of the acoustic space of the program being played was performed. It
can make you feel like you are actually. The present invention has minimal controls, as well as
being visually hidden, which allows the user to maximize the amount of control required to
regenerate the environmental acoustic material.
The system provides a suitable and effective user interface. This user interface corresponds to
the required functions exactly, the desired program to be played, and an understanding of the
display-display section for selecting one or both styles of environment or music in which the
program is played It has a set of input controls that simplifies and facilitates. The playback
system may include a touch screen monitor user interface for selecting various operating modes
as well as programming the playback function. The playback system can be designed to be able
to receive new programs if available. For example, the ATS playback system can be designed to
include removable modules that can be returned to the ATS provider to perform the upgrade. In
another aspect, the ATS playback system may include a replaceable hard disk that can be
removed and replaced with a hard disk containing a new program. In addition, the ATS playback
system may be equipped with a communication link for upgrading by uploading new programs
via a network, such as a wide area network (WAN) such as the Internet.
One example of a playback system configuration includes a speaker system that can be designed
to be compatible with the recording array to reproduce this recording array. In order to meet the
above criteria for hiding the loudspeakers, it is appropriate to use a loudspeaker that reproduces
with a fidelity that meets or exceeds the desired requirements for acoustics and that can be
almost concealed when installed It is desirable to use the device. One example is a ceiling
mounted speaker, mounted flush with the suspended ceiling tile. The speaker itself may include a
magnetically shielded aluminum cone driver, which can use the back, which insulates and
provides an appropriately sized cabinet that maximizes the characteristics of the speaker.
Furthermore, installation in existing hospital rooms, which can not be left open for a long time to
perform the installation process, is much easier and can be integrated smoothly. Unlike
conventional commercial ceiling-mounted speaker systems, the speakers used in the present
invention are 70 V standard in the industry where it is necessary to operate a step-up
transformer and step-down transformer to match the impedance. Low voltage can be used
instead of speakers. With these particular types of loudspeakers, these loudspeakers have a
predetermined distribution pattern over a very large coverage area, which makes it possible to
select the loudspeaker arrangement slightly more easily.
The speakers may be mounted stationary. This allows the speaker not to be physically moved as
well as a wall mounted speaker with a ball and cup type mount, but the coverage area allows the
acoustic field to be adjusted for the patient's bed area in the hospital room It is not difficult to All
you have to do is place the speakers in the appropriate ceiling tiles and adjust the volume of the
individual speaker channels so that the program is balanced where the patient's head in the bed
is placed. Another feature of the ceiling mounted speaker is that it conforms to the fire resistance
criteria of the void space of the building itself. When used with the proper void standard speaker
leads, these speakers can easily exceed existing fire resistance standards. However, the speaker
can be attached to any suitable area of the hospital room, or can be integrated with various
equipment of the hospital room, such as a bed or an end table.
The driver for the speaker is a full range device, enabling very high fidelity sound without the
need for additional filtering to compensate for inefficiencies in conventional designs. The single
driver of this feature significantly reduces the cost of the speaker array. This is because the
number of parts is reduced. When using a full range device, one possible embodiment of the
invention reduces the number of speakers in the surround array to only four instead of five,
including subwoofers. This proves to be much more attractive to prospective hospital customers
who are reluctant to install subwoofers in audio systems. The main purpose of the speaker array
is to introduce the spatial relationships and delays that exist in the original surround recording
space. One purpose is to maintain high quality acoustic fidelity and the resulting surround image.
The ATS playback box can be formed on an essentially small PC motherboard. This unit may
include a hard disk holding an environmental program. In addition, an audio sound board may be
provided, and the computer sends program data to the audio sound board and then converts the
program into an audible analog environment program. Inside the main chassis of the box there is
a motherboard, an audio board, a hard disk, a user interface, a power distribution section and an
audio power amplifier section for driving the speakers. The main power supply to the box can be
supplied by an external power supply plugged into a regular line power supply from a standard
110V wall outlet, reducing power to the level the box itself needs. The unit can be designed to be
low power and extremely quiet, which serves the criteria of hiding and low profile for
environmental therapy systems. This size can be miniaturized to facilitate concealment and to fit
into the decoration of the hospital.
By forming the ATS in the infrastructure of the computer system, the design can be extended to
improve the features that the unit can contain in the future. The computer system used also
incorporates a network interface. Because this interface is provided, it can incorporate facilities
for upgrading program material over the Internet or other wide area networks. This makes the
unit very flexible and eases the end user's responsibility of having to keep upgrading.
The computer also serves as a liaison to the user by providing information about the program
being played and how to play it via the display section of the user interface. The user interface is
provided with an input control device such as for the user to select a program, for adjusting the
volume, and the like. For ATS boxes, the complexity of the user interface of a typical home
theater system can be eliminated. One purpose is to keep it as simple as possible and to define
the function clearly to the user so that the ambiguity is minimal.
Within the ATS case, a compact but efficient power amplifier can be accommodated to handle the
drive of the surround array speakers. The amplifiers are custom made specifically to the speakers
they drive. This allows the tonal characteristics provided by the speaker to be created as it allows
for a more transparent sound source as if the speaker system were not actually there. The
amplifier can equalize the output signal driving the loudspeaker, ie adjust the timbre, to
compensate for inaccuracies in the reproduction of the sound. For example, to more accurately
reproduce the recorded sound, it provides equalizing adjustments that can be operated to flatten
the speaker output. Equalizing adjustments may be made at the time of mixing or to the ATS box
adjusted for a particular set of speakers.
Recording algorithms for recording natural sounds are also an important feature of the present
invention. It is waterproof and designed to be an animal shelter. The height of the microphone
assembly when it is inserted into the ground is about 30 inches. This places the microphone
slightly above the ground, approximately two feet. The height may vary depending on the
recording environment and the desired result. The top of the microphone cage is hemispherical,
which allows rain to flow down the sides rather than dripping into the microphone area. The legs
of the case may be made of 302 stainless steel so that it can be inserted into the ground with
very little corrosion. The windbreak may be a nylon material similar to that used in Rycote-type
microphones. Many other materials that are somewhat weather resistant may be used while
buffering wind noise to achieve the same result. The invention comprises features for the fight
against rodents such as rats. A knitted wire mesh cage covers the microphone cable from the
external connector. The microphones that can be used inside the cage are DPA miniature
condenser microphones. Less expensive Shure microphone products may be used.
With regard to ATS playback "boxes", the system handles our requirements, can support
operating systems other than Windows, and has an appropriate combination of computer
performance with appropriate actuation drivers to operate multi-channel audio. It is also good.
The system is operable to stream individual audio files from the hard disk to an audio circuit for
D / A conversion.
One example includes a Dolby AC3 audio decoder. This is to help compress our file system very
much without losing fidelity. It is in public places to help lower the price tag. However, due to the
size of today's hard disks, the entire environment catalog can be stored on one hard disk in the
original uncompressed 48k PCM format, but still has room.
These and other advantageous features of the present invention will be in part apparent and in
part pointed out hereinafter. For a better understanding of the present invention, reference is
made to the accompanying drawings.

In accordance with an embodiment of the present invention, various figures are shown in FIGS. 19, and all the various figures of the accompanying drawings, with respect to similar and
corresponding parts of the invention, like reference numerals throughout. Used consistently.
Furthermore, it should be noted that the first digit of the reference number for a given article or

One embodiment of the present invention is a method of recording natural sound at a recording
location with a suitable microphone array, recording a signal with a high resolution recording
device, including the formation of an audio bed, and another reproduction The present invention
teaches a novel apparatus and method for performing ambient therapy, including the steps of
playing a recorded sound with a tuned playback system in place.
The details and various embodiments of the present invention can be better understood with
reference to the accompanying drawings and the specification examples of various electronic
devices incorporated herein by reference.
Referring to FIG. 1, one embodiment of a microphone matrix array and recording system 100 is
shown. The preferred embodiment shown in FIG. 1 is an array of 200 feet by 200 feet, in which
each of the four microphones 102, 104, 106, and 108 is 60. One each at the four corners of a
space of 96m x 60.96m (200 feet x 200 feet). Here, dimension A is about 60.96 m (200 feet) and
dimension B is about 60.96 m (200 feet). The dimensions of the array can be adjusted to fit well
with a given natural environment, but for many natural environments such as, for example,
forests, about 200 feet by about 200 feet Arrays are preferred. These independent microphones
record for each sound with a predetermined time delay determined by an array of 60.96m x
60.96m (200 feet x 200 feet) between microphones.
Articles 110, 112, 114, and 116 show custom made cage father rings. Here, the microphone is
suspended in a bell and tongue or bell and clapper configuration. Protect the microphone from
moisture and dust with a case or cover. The cage can be attached to porcelain insulator 118. The
microphone output signals M1, M2, M3 and M4 respond to and represent ambient sounds. These
signals are received by the preamplifier 120 and then monitored and recorded by the monitor /
recording system 122. Preferably, a rod 126 is further provided at a predetermined proximity
from the array to attract and remove static electricity. The rods are preferably about 7 feet in
height from ground and 3 feet to 4 feet from the array, preferably copper. . The materials of the
gauge and microphone transmission lines may be different, but are preferably selected to
minimize signal noise and interference. Furthermore, a windscreen 124 is provided which shields
the microphone from the wind.
Referring to FIG. 2, there is shown a tuned, adapted speaker array-reproduction system 200
designed to maximize environmental therapy effects. Here, four adapted speakers 202, 204, 206
and 208 and an optional center channel subwoofer 210 are shown. Regeneration system 212
regenerates the signal through amplifier 214, which generates S1, S2, S3, S4, and C. The center
channel is optional, as shown.
Environmental therapy consists of two major components: Recorded sound software, and Made
of a specific playback system or delivery system.
The recording process is performed in a microphone configuration, referred to herein as "4.1"
technology. This means that the reproduced sound goes to the four matched speakers and an
optional subwoofer. A total of four microphones arranged in an array of 60.96 m x 60. 96 m
(200 ft x 200 ft) can record other natural sounds such as the natural sounds and waves of the
four seasons in this way . The playback system may include four speakers in order to play the
sound in four channels, each of which corresponds to the sound captured by each of the four
microphone channels. The playback system may, in another aspect, include a subwoofer or
center channel to emphasize and reproduce low frequency sound. This is called "4.1" technology.
However, a "4.0" technology playback system without subwoofer channels may be used. The 4.0
or 4.1 technology may be alternately selected to best fill a particular regeneration facility.
After recording the natural acoustic space of the season or environment, including several
consecutive or sequential or random times of the recorded material, the audio "bed" is reviewed,
compressed and edited. Several months of recordings can be formatted in an hour to deliver
environmental therapy.
The microphones used have the specification that the audible range is wide and omnidirectional.
For example, in microphones, there are two different brands of desired specifications. One brand
that can be used for setup is Shubrand's electret condenser MX183 microphones, which may be
permanently installed as they are known to be relatively robust in various climatic conditions .
Additionally, a DPA brand 4060 electret condenser microphone may be used. Other microphones
of similar performance specifications may be used.
The pickup pattern of the microphone may be "all directions". The microphone picks up sound
from all directions. These microphones are small "Lavaliere" microphones (microphones that are
used by hanging from the neck or clipped on clothes). The microphone picks up various audible
sounds at the installed location. The microphone converts audible sound energy into electrical
signals and transmits these signals to the microphone's preamplifier (via wiring, wireless
transmitters, optical fibers, etc.). The amplified electrical signals from each microphone are later
handled in various ways. (1) convert to an audible signal for the purpose of monitoring; (2)
electronically change the content, ie, remove low frequency interference, remove hum, etc., and
(3) a suitable high resolution medium Convert to digital signal for storage on (tape, disk, etc).
The signals of these four microphones are electrically transmitted by underground cables to a
multi-channel high-resolution digital audio recorder, which is a storage medium for raw audio
signals. Microphone mounts: (1) Protect the microphones against the weather and reduce the
amount of unwanted wind noise picked up by the microphones; custom-designed windscreens
coated with tarpaulins (2) Moisture, signal Custom-made “cages” manufactured to suspend
microphones upside down in a bell and clapper configuration, and (3) porcelain insulators to
which cages can be attached, so that the purity of the Including.
A solid copper rod of approximately 7 feet is placed on the ground approximately 3 feet to 4 feet
apart to attract static electricity that can impair the purity of the signal. It is also good. The
transmission cable may extend 304.8 m (1000 feet) to the microphone preamplifier and then to
the monitor system and a 24-bit high resolution multi-channel digital audio recorder with 48 khz
digital resolution. All four channels can be recorded simultaneously.
After recording the raw audio signal, time compression is performed to form an audio "bed".
Digital audio signals are transmitted from digital audio tape to computer audio recording, editing
and playback systems with great flexibility. The music is then custom designed and integrated at
a specific time on the audio bed based on events triggered by the natural sounds that occur in
the ambient acoustic space. Custom sound effects may be created and included to enhance
natural sounds and music content.
The content of the music can be guided and customized to meet the purpose of each specific
purpose of the therapy, for example pain relief and the birth of a child. This is an important issue
because it addresses the composer's creative process inspired by the sounds of nature. For
objects drawn by purpose. A natural sound event is used as a key or trigger to guide the musical
overlay to achieve the desired desired therapeutic effect.
The method and system of the present invention is applied not to create music for musical
purposes nor to create sound for acoustic purposes, but to generate and create specific outcomes
that must be performed with healing, therapy etc. Creative process.
The hardware components of the delivery system are as follows.
(1) Reproduction unit system, (2) Specific cord wire, (3) Shielded speaker system, and (4)
Amplification system.
Another hardware component is to set up and adjust the environmental therapy listening room
so that the patient receives the most benefit from this treatment modality. The concept and use
of treatment can be used for: Transient spikes to cover up unwanted noises such as (1) pain
relief, (2) anxiety relief, and (3) "hospital sounds" surrounding the environmental therapy room.
One theory upon which these pains and anxieties occur is due to the evolution of the human
auditory system. In the human auditory system, sound addresses the auditory nerve, makes it
impossible to know where you are, and produces various effects like a day dream.
One important feature of the preferred embodiment is that it returns to the 60 feet x 200 feet
algorithm or array formed at the time of the recording "bed". The listener / patient can place his /
her heart in the “stereoscopic acoustic space” due to the techniques of the present invention. If
the musical content is provided in a monaural or stereo manner, the unique stereoscopic
surround component of the present invention is not provided. The effect of the therapy is not the
same as if it were not provided with Surround 4.0 or 4.1.
More specifically, musical content acts on emotions. The recording process in 60.96 m x 60. 96
m (200 ft x 200 ft) form with the best equipment, the specifically designed musical content, and
the delivery system as a control device to output the material , All are important to the method.
Regeneration system configurations may have different performance specifications in various
embodiments without departing from the scope of the present invention. The following table
shows three possible implementations of various performance specifications.

illustrative of an example of how to implement the system. However, specific components may be
varied without departing from the scope of the present invention.
Referring to FIG. 4, the main function of the ATS analog board is to extract the low level audio
output signals from the ATS CPU motherboard and add appropriate amplification to these signals
to drive the array of loudspeakers . A pre-amplifier design using a voltage controlled amplifier
(VCA) is designed to include one master controller and individual trim controllers 404, 406, 408,
410 for each channel 403, 405, 407, 409. it can. ATS is a multi-channel audio output device.
This means that there are many simultaneously operating separate audio channels that need to
be controlled simultaneously in some reasonable way. One embodiment of the ATS analog board
is described in detail below. However, the analog board design can be varied without departing
from the scope of the present invention.
The conventional method is to use a stacked potentiometer type volume control. In essence, it is
to use four volume control devices stacked on top of one another and actuated by a single
mechanical rotation. This method is technically low but very reliable. However, there are
drawbacks. The first and most serious disadvantage is that individual channels can not be
trimmed slightly, as all the pots are connected to one another. When using an ATS, all four
channels need to be controlled simultaneously, but each channel can be trimmed independently
to absorb possible mismatches in the placement of the speakers in the final installation.
Therefore, the voltage controlled amplifier is used to design an analog board according to the
above criteria. In essence, VCA is a kind of monitoring potentiometer that changes the gain
through VCA with a simple DC control voltage. By making each channel the same structure with
VCA preamplifiers, each channel can be linked together, driven from one central control source,
as well as individually trimmed.
Efficient audio power amplification can be implemented to drive a typical low impedance
loudspeaker. This is because the ATS needs to be designed to provide a power amplifier that is
sometimes placed in a small, compact equipment shelf or closet and that is reasonably efficient
and does not generate excess heat. The power amplifier section of the ATS is called switching
power amplifier or class D amplifier 420. In conventional audio power amplifiers, many of the
inefficiencies are consumed by converting a predetermined amount of available current into heat
at the output device of the amplifier rather than actually being transferred to the loudspeaker .
This particular effect is inevitable due to the nature of the attempt to control the current applied
to the load in a linear fashion. What the switching power amplifier does is to deliver almost all
the current to the load with little waste of the amount of current consumed by the power
amplifier's internal output device. This is done by making the output device's response non-linear
and just a separate binary response. The output device is either fully on and adding current to
the load or off and not adding current to the load.
The ATS reproduction system performs main noise reduction control. This controls all the
channels simultaneously. As part of the function of the analog board, a main muffling 422
controller may be incorporated to facilitate the need to turn off the sound suddenly if there is a
reason for the end user to turn off the sound suddenly. This function is enabled by simply
pressing a push button that mutes the audio amplifier. Pressing another button on this causes the
mute circuit to disengage and the audio amplifier to function normally.
The analog board can be flexibly designed and remotely controlled to include a software
controlled volume control to return to a preset volume level. By incorporating a VCA-based
preamplifier, the ATS can be made into a software-controlled advanced system. This allows the
implementation of a software controlled loudness function that includes predetermined loudness
levels that will recall a particular scene in the future. Likewise, wireless remote control can be
relatively easily added to the system without redesigning the preamplifier circuitry.
The audio signal from the CPU motherboard is transmitted to the ATS analog board, and when
the ATS analog board receives the audio signal, this signal is input to the VCA amplifier. This can
be seen in FIG. The exit current level of the audio signal from the VCA, ie the gain through the
amplifier, is controlled by a linear DC control voltage. This is consistent with the total log
throughput from the VCA. There are two control voltage sources for the VCA of each channel
provided on the ATS analog board.
The first control voltage source is from the main volume controller. This may include a single
potentiometer that generates a control voltage based on the position of the volume controller. A
clockwise rotation may be configured to generate a positive gain through the VCA. This
particular control voltage amplifier may be configured to provide a dual slope response. When
operating the unit at a low level, the volume control affects a large range of gains. The controller
may be designed such that the slope of the gain decreases at about the 1 o'clock position of the
volume controller, so that large movements of the controller cause the gain to shift much smaller.
This can help to prevent an accident that may occur if the control device is suddenly turned
The second control voltage source is from an individual trim controller. The interface to this
controller can be located at the back of the ATS, and can be due to obstacles placed in the room
or by several choices in installing the speaker, the possibility of loudness of the speaker at the
listening position To absorb differences, the installer of the system can adjust the individual gains
of the ATS channels. This control is simply linear control, with gain and attenuation of ± 15 dB
over about 30 dB. These two control voltage sources are then summed 424 to generate a single
control voltage, which is supplied to VCA. Each channel has its own unique trim control and is
added to the main volume control to generate a unique control voltage for each channel. The
audio current is supplied directly to the power amplification section after leaving the VCA
section. See FIG. 4 for a diagram of the power amplification section.
The output of the VCA is injected into the power amplification section. The power amplifier may
be a class D pulse width modulation type. The incoming audio signal is modulated with a high
frequency triangle wave and the pulse width modulated output is provided to a series of
transistors that control the current delivered to the loudspeaker. The output aspect is referred to
as a differential output or a balanced bridge output. This means that there is no solid ground
reference of unbalanced output terminated floating output. However, instead there are
symmetrical signals that are out of phase, and these signals act on the loudspeaker as a kind of
push-pull. This allows the amplifier to generate a net voltage output across the load
approximately twice that which can be obtained by operating the amplifier in an unbalanced
terminated mode only.
The power amplifier design may incorporate a shutdown protection circuit that shuts down the
amplifier if the loudspeaker fails or the amplifier is overused. Additionally, circuitry may be
included to effectively shut off the power amplifier and provide a mute function. This function
can be provided directly on the amplifier section as a separate circuit, instead of program
controlled software that operates the ATS. The mute circuit can be in that state when the user
presses the push button switch. One press of the button shuts down all four amplifiers on the
analog board. This condition remains latched until the user presses the push button a second
time and the mute circuit reactivates the amplifier.
All the functions described above for the ATS analog board function work in concert with one
another as a whole and are specific to the requirements of the ATS regenerator, single board,
four channel preamp / power amplifier Provide a solution. The particular details of the board
design may vary without departing from the scope of the present invention.
The user interface of the present invention may include an LCD touch screen monitor (see FIG. 5)
and a display driver, and the user interface screen is provided by the ATS software user interface
application. Software applications for generating such user interfaces are well known to those
skilled in the art. The user interface application can operate to implement various features,
including the following features.
Referring to FIGS. 6-9, many of the user interface screens, including the main menu interface
screen 600, include a program display window 602 that displays program titles and tracks to be
played, program numbers and track numbers. In addition, a program and track skip button 604
is provided on the main menu to allow the user to skip forward to the next program and track or
skip backward to the previous program and track. In addition, a stop-play-pause-repeat button
606 is provided. The repeat function, when selected, repeats the program or track being played.
Three environmental modes 608 are provided. This is because there are three ways to listen to
any environmental title: 1) environment and music, 2) only environment, 3) only music. The
environment relates to the recorded natural sounds.
The main menu also provides a push button for selecting the chain program 610. The options for
chained programs relate to "chaining" one program with another (see FIGS. 8 and 9). This can be
done for any of the three environment mode functions. An example of a chain is to connect only
a night song (NIGHT SONG) / environment to a summer song (SUMMER SONG) / music only, and
to connect this to a bird song (BIRD SONG) / environment and music. The program matches the
environment title, which includes environment and music, environment only and music only. The
program relates to the program or title loaded into the memory. When selecting a program for
playback, the name is shown in the upper center of the main program display window. To find
and find a program, use the forward-backward "skip" <> button on the window and the adjacent
program function to find a list of available programs. The track of the program can be searched
by the Previous track button and the Next track button. A track relates to a subfile or recording
segment within a program or title.
The main menu is further provided with a timer button 612 for selecting a timer option (see FIG.
7). The timer function is an alarm clock type function for setting the start time of the program.
The purpose of the timer function is to automatically start the selected program. This can be used
to "reset the biorhythm" of people who have lost their sense of day and night. The timer function
allows the user to select a preset start time for a given program or chain if the given program or
chain is appropriate for the selected start time.
The new download indicator 614 allows the user to know when ethernet downloads are
available. The download indicator, when flashing, indicates that a new program is available for
download. The environmental therapy playback system can access the new program via a
communication port or a network to a wide area network or a local area network. To access and
download, the user need only press the flashing download button. When the download is
complete, the "Loaded" button flashes and indicates to the playback system that the download
was properly done. The download complete button may also flash for two weeks to indicate the
download if staff changes during the download function.
One example of an application of the ATS regeneration system is for use in a hospital
environment to dissipate pain. For example, some users have patients with pain from buttock
surgery. In this distressed state, several medical studies have shown that patients feel mentally
trapped. Getting out of this feeling is obviously difficult and almost impossible. Pain can be
dissipated by playing the "Summer Song" environment and music, and placing the patient in a
summer thunderstorm. The concept is that people listen to this music on two levels. For example,
natural sounds such as thunder, the sound of rain drops hitting hard surfaces, the sound of wind,
etc. will develop awareness of where we are right now, and when the music part starts, this will
become a more “advanced” function of the brain Address Musical overlays are composed by
using natural sound events as a guide or trigger, so that the music flows naturally with the
natural sounds without overtaking the natural sounds. The concept is that the pain signal travels
slower than the auditory signal. So, in theory, the body's "ear-gate" function can divert attention
from one signal to another. Compressing the natural sound for several hours and editing it into a
relatively short format, such as an hourly format, the human eargates flood the sound bed, which
dominates and distracts the listener's mind. Thus, a month-long recording in the forest is
compiled into an hourly format filled with autumn sounds, such as a wind blowing on a meadow.
This can be used as a trigger for a music overlay composed on demand.
To program the selection, the user goes to the main screen program, selects a program such as,
for example, an Autumn Song (AUTUMN SONG) with the arrow keys, and turns on the program
display window. The user uses the "mode" button to select and play the environment and music.
If the user chooses to extend the regeneration period, the user can do several things. That is, the
program is repeated only by pressing the repeat button repeatedly until the user presses the
stop. 2.) "Connect" this program to another aspect of the program, such as music only, or
environment only, or connect it to another program entirely (eg, a bird song) In order to form
such a chain or chain, the user selects the chain button. At this time, a chain setup screen
appears, an autumn song is displayed in the program display window, a chain 1 of x is displayed
in addition to the autumn song. This means that it is the first link of the selected chain. Repeat
this for all programs in the chain's link. 3. After entering the chain sequence, if the user wants
to start this "chain" at a specific time, he can select the "timer" function. "Set" is displayed to the
right of the main function button. The start of the program can be set just like an alarm clock. Set-open main timer window-select am (morning) or pm (pm)-select hours and minutes-press to
turn on-execute-to turn off this function, select off. This can be done in a large "settings" window
or in the main screen timer window (right off-on). Red is the "stop" feature. There are 1.2 timers
am and pm, and the timer function is the function of "go", so "green light is go" which is green
2.6 chains are possible, each chain Two timers are possible, resulting in a total of 12 timers.
Another example is when the patient is in a delusional state where daytime and nighttime
sensations are lost. The user attempts to reset the patient's biorhythm by using a timer function
in conjunction with a particular program sequence. 1. Select only the bird song environmentAfter adding to the chain-Connect to the bird song environment and music-Activate the timer and
set it to 7 am-Press-Run-The purpose here is In the duality of our hearings, we add the "advanced
function" hearings to a high degree by adding music after slowly awakening the patient with the
sounds of the birds of our evolving hearings . This sequence spans about 2 hours. 2. Select the
night song "Environment & Music". -Add to the chain,-Connect the night song environment and
music to the night song environment only,-Activate the timer and set it (10 pm),-Press,-Execute,The purpose here is the am sequence Is to lower the activity in the same way.
