US 2010/0246869 A1 · SYSTEM FOR AUTOMATIC FITTING USING REAL EAR MEASUREMENT

Abstract

According to a method embodiment for performing a real ear measurement (REM), a stimulus signal is transformed into a frequency domain stimulus signal with a plurality of frequency ranges. The frequency domain stimulus signal is amplified with a desired gain for each of the plurality of frequency ranges to provide an amplified stimulus signal. The amplified stimulus signal is transformed into the acoustic signal in the ear canal, which is detected to provide a detected acoustic signal, and the detected acoustic signal is transformed into a frequency domain detected signal with the plurality of frequency ranges. A sound level for the plurality of frequency ranges is measured. The desired gain for the frequency ranges is automatically adjusted based on the measured sound levels and the desired sound pressure levels for the plurality of frequency ranges. The method can be performed within a hearing assistance apparatus.

Dependent claims

A hearing assistance device for a wearer having an ear and an ear canal, the wearer having a plurality of target gains determined for the ear, comprising:

a microphone adapted to sample sound from the wearer's ear canal;
a receiver adapted to play a sound stimulus to the wearer's ear canal;
and
hearing assistance electronics in communication with the microphone and the receiver, the hearing assistance electronics programmed to process signals received by the microphone to automatically self-correct frequency dependent gain of signals played by the receiver in the wearer's ear canal to approximate the plurality of target gains.
