Mind the Ports! The Effect of Severe Microphone Inlet Occlusion
Maintaining microphone ports, ensuring they are free from occlusion, is very important to the function of the hearing aid. Severe occlusion of the rear microphone port may produce values of greater than 15 dB of increased output for non-frontally arriving sound that is otherwise attenuated by the directional processing.
Compression in Hearing Aids: Why Fast Multichannel Processing Systems Work Well
References in the academic literature maintain that flattening of the speech envelope by fast multichannel amplitude compression reduces speech intelligibility—references that typically ignore the counteracting effect of recruitment. A perspective from one of the pioneering engineers of compression in hearing instruments.
