Automated Real Speech Hearing Instrument Adjustment System
US Patent:
2008029, Dec 4, 2008
Filed:
Apr 21, 2008
Appl. No.:
12/106893
Inventors:
Michael Poe - Seminole FL, US
Anthony Quick - Orlando FL, US
Srinivas Chari - Winter Springs FL, US
Don E.K. Campbell - Winter Springs FL, US

International Classification:
H04R 29/00
US Classification:
381 60
Abstract:
A method for fitting a hearing instrument comprises placing the hearing instrument in situ includes receiving an audiogram of the user, determining a target gain for the hearing instrument as a function of the audiogram, exposing a reference sensor located adjacent the hearing instrument to an external speech signal, measuring an external sound pressure level (SPL) via the reference sensor, exposing a probe sensor coupled to the inside of the ear to the output of the hearing instrument while the hearing instrument is in situ, measuring an internal sound pressure level (“SPL”) inside the ear of the user via the probe sensor, determining an offset gain as a function of the external SPL, the target gain and the internal SPL, and automatically adjusting a gain of the hearing instrument according to the offset gain. A system for automatically fitting a hearing impaired person with a digital hearing aid in situ includes a digital hearing aid, a reference volume sensor, a probe sensor, a sound mapping module and a parameter control module.

International Classification:
H04R 29/00
US Classification:
381 60
Abstract:
A method for adjusting a hearing instrument to reduce feedback by placing a hearing instrument having an adjustable frequency response in a wearer's ear, providing a probe microphone for measuring the sound pressure level inside the ear and a reference microphone for measuring the sound pressure level outside the ear, exposing the ear to a stimulus and a dynamic event, determining the gain as a function of frequency from the difference in sound pressure level measured by the probe microphone and the reference microphone, identifying a feedback peak where the frequency is in the center of a range of frequencies and corresponds to the maximum gain in that range of frequencies and adjusting the hearing instrument to reduce the gain at a frequency corresponding to the frequency of the feedback peak.
