Abstract

A hearing aid having a plurality of frequency bands is calibrated by evaluating the response of the hearing aid in each band and programming the hearing aid to produce a specific sound pressure level in each band, thereby providing a calibrated instrument that can be used for both evaluation and compensation of hearing loss. The sound pressure levels are preferably the same for each band. The evaluation step is preferably performed at the center frequency of each band.

Claims (14)

1. A method for calibrating and programming a hearing aid having a plurality of bands of audio frequency, the hearing aid including a microphone and a speaker, said method comprising the steps of:

a) calibrating the hearing aid by:

i) inserting the hearing aid into an apparatus, the apparatus having a speaker for generating a source audio signal of a desired frequency proximate the microphone of the hearing aid for each of the plurality of audio frequency bands, and the apparatus having a microphone for detecting audible signals emitted from the speaker of the hearing aid in response to the source audio signals;

ii) evaluating the response of the hearing aid in each band to the source audio signal; and

iii) adjusting the hearing aid, based upon the evaluation of the response of the hearing aid in each band, to produce predetermined sound pressure levels in each audio frequency band;

b) inserting the hearing aid into the user's ear after step a) has been performed; and

c) programming the hearing aid, while the hearing aid is within the user's ear, the programming step including:

i) providing the hearing aid user with a programmer linked to the hearing aid;

ii) using the programmer to cause a first tone to be played by the hearing aid in the user's ear within a first of the audio frequency bands;

iii) allowing the user to operate the programmer to increase the gain of the hearing aid within the first audio frequency band, and to signal when the first tone can be heard by the user; and

iv) using the programmer to cause a second tone to be played by the hearing aid in the user's ear within a second of the audio frequency bands; and

v) allowing the user to operate the programmer to increase the gain of the hearing aid within the second audio frequency band, and to signal when the second tone can be heard by the user.

2. The method as set forth in claim 1 wherein the predetermined sound pressure levels are substantially the same in each audio frequency band.

3. The method as set forth in claim 1 wherein said evaluation step is performed using a source audio signal having a frequency located substantially at the center frequency of each audio frequency band.
