Abstract
In the field of Hearing Aids the most important parameter for a microphone is performance versus size. This is not a simple parameter like Signal to Noise ratio - versus volume, but the size is strongly connected to the overall space used in the Hearing Instrument. Especially because in most hearing aids two microphones are used, in a matched pair configuration, to
create directionality.
Power consumption is always a limiting factor in these kinds of applications. We will present tradeoffs and results for the different parameters, and design options to come to the final design that can be produced in an industrial way.
