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.
