Abstract
The present disclosure relates to the inclusion of amplitude compression inside a hearing aid remote microphone or audio streaming device. Compressor design is improved by using one local and one remote compressor operating in parallel. The subject matter will reference remote microphones as the primary use case. In one embodiment, hearing aid microphone audio and remote microphone audio are treated as two separate streams within the hearing aid, assigning each to a compressor and mixing the audio streams afterward. In another embodiment, a compressor is developed for the remote microphone to offload that portion of the signal processing.
