Hearing device test system for non-expert user at home and non-clinical settings
First Claim
1. A hearing device test system for use by a non-expert user, the hearing device test system comprising:
- a hearing aid device comprising a sound processor and a speaker;
a portable test unit comprising a test microphone acoustically coupled to an exterior of the portable test unit via an acoustic calibration cavity, the test microphone configured to produce a calibration signal input responsive to acoustic calibration stimuli provided by the speaker of the hearing aid device, the portable test unit further comprising a coupler at an opening to the acoustic calibration cavity configured to receive the hearing aid device at least partially therein; and
a processor associated with the hearing device test system configured to measure a level of the calibration signal input and confirm a calibration of the hearing aid device if the level of the calibration signal input is within a range of acceptable reference levels for the hearing aid device.

Abstract
A hearing device test system for use by a non-expert user may include a hearing device comprising a sound processor and a speaker and a portable test unit including a test microphone acoustically coupled to an exterior of the portable test unit via an acoustic calibration cavity. The portable test unit may include a coupler at an opening to the acoustic calibration cavity configured to receive the hearing device at least partially therein and the test microphone may be configured to produce a calibration signal input responsive to acoustic calibration stimuli provided by the speaker of the hearing device. The hearing device test system may also include a processor associated therewith and configured to measure a level of the calibration signal input.

18. A portable test unit comprising:
-
an acoustic chamber defining an acoustic calibration cavity acoustically coupled to an exterior of the portable test unit, wherein the acoustic calibration cavity is configured to accommodate a hearing aid device or an acoustic adapter at least partially within; a test microphone acoustically coupled to the acoustic calibration cavity, the test microphone configured to produce a calibration signal responsive to an acoustic calibration stimuli from the hearing aid device, wherein the hearing aid device comprises a speaker and a sound processor; and a processor configured to receive the calibration signal and confirm a calibration of the hearing aid device if a level of the calibration signal is within a range of acceptable reference levels for the hearing aid device.

19. A method of checking a calibration of a hearing aid device, the method comprising:
-
acoustically coupling a hearing aid device to an acoustic calibration cavity of a portable test unit, wherein the hearing aid device comprises a sound processor and a speaker; transmitting an acoustic calibration stimuli from the speaker of the hearing aid device to a test microphone within the portable test unit; producing a calibration signal by the test microphone in response to the acoustic calibration stimuli; transmitting the calibration signal to a processor associated with the portable test unit; and comparing a level of the calibration signal to a range of reference levels; and confirming a calibration of the hearing aid device if the level of the calibration signal is within the range of acceptable reference levels for the hearing aid device. - View Dependent Claims (20, 21, 22, 23, 24)
