DESCRIPTION JP2008125113
A hearing aid device with a test operation mode and a listening mode that utilizes an interactive
process that enhances the listening experience for a hearing aid user. The invention is achieved
using a system comprising a hearing aid unit and a sound source. Hearing aid is achieved using
conversational and iterative processes transferred by a personal computer (PC) or similar device.
The user is prompted to hear the various signals delivered by the PC, thereby testing the
frequency response of each ear and headphone combination. Once the test operation is complete,
personalized compensation factors are created to optimize the user's response experience. These
compensation factors are stored in the hearing aid and can be downloaded by infrared, radio
frequency or wired or wireless like magnetic or electromagnetic coupling. [Selected figure] Figure

Unconnected Personal On Demand Audio Entertainment Device Allowing Wireless Download of
Content Field of the Invention
[0001]
The present invention relates generally to audio headphones or hearing aids, and more
particularly to headphones or hearing aids that allow compensation for imperfections in the
listener's hearing.
[0002]
The most popular current practice of personal on demand audio entertainment is conveyed by
headphones which are connected to the power supply by wire.

The sound source may be mobile, typically as in a Walkman®, as shown in FIG. Here, the audio
content is stored on a magnetic, light or solid state medium (not shown) contained within the
player 10. The signals from these media are converted to an audio signal to be amplified prior to
being transmitted by wire 12 and converted in headphones or earphones 14. Other sources of
sound typically do not have to be mobile as in a home stereo system.
[0003]
Deafness is often attached to hearing aids in both ears. Transducers for both headphones and
hearing aids are typically electromechanical devices that are not commensurate to manufacture
within an affordable price. The auditory responses of the left and right ears do not match
perfectly. However, the current headphone device assumes that the responses match. Due to the
imperfections of both the transducer and the ear, the hearing of the position of the audio source
can be shifted from the original position. If the ear response is measured and corrective hearing
aids are manufactured, correct compensation can not be achieved due to imperfect matching of
the transducers.
[0004]
Several methods have been devised for the improvement of hearing aids. US Patent No. 6,104,
822 by Melanson et al describes a hearing aid with a multi-user selectable digital signal
processing method to improve hearing in different listening environments. No. 6,128,392 and
European Patent 0933970 A2 by Leysieffer et al. Describe a hearing aid that uses finite impulse
response filtering to achieve feedback compensation. Hanson (European Patent 0 634 084 B1)
describes a hearing aid feedback compensation device in which the application rate varies
depending on the signal conditions. Stockham, Jr. U.S. Pat. No. 5,500,902 to T. et al. Describes a
hearing aid having a plurality of band pass filters with corresponding automatic gain control.
This allows for volume compensation over different frequency ranges. Stockham, Jr. U.S. Pat. No.
6,072,885, et al. Also develops the previous invention by providing discrete low and high
frequency output transducers.

Improvements in the spatial perception experience have also been made to audio listeners. U.S.
Pat. No. 5,136,651 to Cooper et al describes an audio system in which compensation for head
diffraction is achieved. No. 5,939,656 to Suda et al. Describes an audio system that compensates
for differences in frequency and sound image location between speakers and headphones. U.S.
Pat. No. 6,005,947 to Lim et al describes a sound processing system that acoustically mimics the
sound quality of an ideal listening room. No. 6,111,958 to Maher et al. Describes an audio
processing system that improves spatial imaging of signals.
[0006]
The wires often used in headphone systems interfere with the operation of the user and are
prone to handling failures. Several methods have been devised to eliminate this problem. One
such method is U.S. Pat. No. 5,247,293 to Nakagawa et al. Shown in FIG. 2, where the player 10
and the headphones 14 are separate. The two units are combined by radio frequency to allow
transmission of the audio signal to the remote unit 18 with lesser and less complexity. The
headphone 14 still uses the wire 12. The remote unit 18 allows control of the player 10
functions such as volume, fast forward, etc. Vertical Horizon sells a headphone unit (Korean
patent continuation number 99-24278) that allows 32 MB download of MP3 audio content from
a computer parallel port. In this case, storage and control are all included inside the headphone
unit. Downloading is accomplished through hardwired connections. Sennheiser sells a wireless
listening system in which a transmitter unit is connected to an audio source. It is coupled to a
pair of headphones via a 900 MHz radio frequency.

conversational process, which achieves compensation for imperfections in the user's hearing.
[0008]
A second object of the present invention is to provide an audio headphone device having a
speech process in which compensation for imperfections in the user's hearing is achieved.
[0009]
Another object of the present invention is to provide an audio headphone device having a speech
process in which compensation for imperfections in the user's hearing is achieved and correction
information is stored in the sound source.

source.
Headphones or hearing aids are achieved using speech and repetition processes transferred by a
personal computer (PC) or similar device.
The user is prompted to hear the various signals delivered by the PC, thereby testing the
frequency response of each ear and headphone combination.
Once the test operation is complete, personalized compensation factors are created to optimize
the user's response experience.

downloaded by wired or wireless such as infrared, radio frequency or magnetic or
electromagnetic coupling.
In the case of a headphone unit, the compensation factor can be stored in the headphone or in
the sound source.
In addition, the headphone unit can be operated by wireless means using infrared, radio
frequency, magnetic coupling or other electromagnetic means for both test operating mode and
listening mode.
[0017]

Referring to FIG. 3, a system overview of one embodiment of the present invention used in
conjunction with a headphone system is shown.
A personal computer or other sound source 20 is connected to the base unit 22 by wire.
The preferred wireless headphone unit 14 includes a receiver, a converter for converting digital
information to an analog audio signal, and a transducer for converting the amplified and
amplified audio signal to sound. Wireless transmission may be accomplished using infrared, radio
frequency, magnetic coupling or other electromagnetic means.
[0019]
To operate the unit, user 16 is prompted to select a frequency and adjust the balance at that
frequency until the sound is perceived to be centered between the left and right channels. For
example, if the left channel is perceived as weaker, the balancing action will enhance the left
signal until it is perceived as equal to the (centered) volume to the user. The process is repeated
at multiple frequencies in the audio spectrum. The single version uses only bass, midrange and
high audio frequencies, whereas complex versions can use many frequencies. The balanced left
and right signals prompt the user to equalize the system to compensate for perceived differences
in amplitude between different frequencies.
[0020]
At the completion of the balance operation and equalization process, the setting coefficients are
preferably downloaded to the headphone unit 14. Alternatively, the coefficients are stored in the
base transmitter or signal source 20. The downloaded coefficients are stored in volatile or nonvolatile memory and used in conjunction with signal processing circuitry such as filters to
provide real time equalization for each ear. Dual communication between the headphone and the
base unit is optional and can be used to provide an initial procedure during downloading of audio
content. In a unidirectional communication system, light emitting diodes on headphone unit 14
may be used to indicate a successful download operation of data.

Referring now to FIG. 4, there is illustrated a system overview of a second embodiment of the
present invention used in conjunction with a hearing aid system. A personal computer or other
sound source 20 is connected to the base unit 22 by wires. A wireless connection is made to the
hearing aid unit 24, which includes a receiver, a converter for converting digital information into
an analog audio signal, and a transducer for converting the amplified and amplified audio signal
into speech. Wireless transmission may be accomplished using infrared, radio frequency,
magnetic coupling or other electromagnetic means.
[0022]
The calibration is similar to a headphone unit. The user 16 is prompted to select a frequency and
adjust the balance at that frequency until the sound is perceived to be centered between the left
and right channels. The process is repeated at multiple frequencies in the audio spectrum. With
balanced left and right signals, the user is then prompted to equalize the system to compensate
for perceived differences in amplitude between different frequencies. At the completion of the
balancing operation and equalization process, the setting coefficients are downloaded to the
hearing aid unit 24 and stored in volatile or non-volatile memory. The coefficients are used in
conjunction with signal processing circuits such as filters to provide real time equalization for
each ear.
[0023]
The hearing aid unit 24 is used in normal mode to amplify sounds such as speech in close
proximity to the user 16. The second mode will allow a public address such as from a theater or
church to be transferred to the hearing aid unit 24 by magnetic means. This signal is detected by
a detector in the hearing aid unit 24.
[0024]
The present invention is a device and method that uses a conversation process to improve the
listening experience for headphone or hearing aid users. The system uses a sound source such as
a PC or similar device. Headphone or hearing aid programming is accomplished using a process
delivered by the sound source. The user is prompted to listen to the various signals, thereby
10-05-2019

testing each ear's frequency response and headphones or hearing aid combinations. When the
user's test operation is completed, personalized compensation factors are created to optimize the
listening experience for the user. The coefficients are downloaded and stored in the earphones.
The download for hearing aid can be achieved by wired or wireless means such as infrared, radio
frequency, magnetic or electromagnetic coupling. In the headphone unit, the compensation factor
may either be stored in the headphone or be maintained at the sound source. In addition, the
headphone unit can be operated with or without wire (using infrared, radio frequency, magnetic
or electromagnetic coupling) for download or audio listening. This system, as well as the benefit
to improve the auditory balance over frequency for the individual, can tolerate slight detection
correction or low cost internal transducers. This can provide economic benefits to the headphone
or hearing aid manufacturer.
[0025]
Although the invention has been particularly illustrated and described with reference to the
preferred embodiments, various changes in form and detail may be made by those skilled in the
art without departing from the spirit and scope of the invention. Will be understood.
