Abstract:
1. A method, comprising: recording signals from a sound environment using a hearing assistance device including one or both of a microphone positioned inside a user's ear canal and a microphone positioned outside of the user's ear canal, the signals having a stereo right (SR) signal and a stereo left (SL) signal; processing the SR and SL signals to produce left surround (LS), left (L), center (C), right (R) and right surround (RS) signals using a processor; generating a processed version for each of the LS, L, C, R, and RS signals by application of a head-related transfer function at an individual angle of reception for each of the LS, L, C, R, and RS signals using the processor; mixing the processed version of the LS, L, C, R, and RS signals to produce one or both of a right output signal (RO) and a left output signal (LO) using the processor; transmitting the RO signal directly from the processor to a right hearing aid, transmitting the LO signal directly from the processor to a left hearing aid, or transmitting the RO signal directly from the processor to the right hearing aid and the LO signal directly from the processor to the left hearing aid; and fitting the right hearing aid, the left hearing aid, or both the right and left hearing aids using the RO and LO signals.
