Hearing instrument microphones :: Knowles
Hearing Instrument Microphones
- Complete range of configuration options
- Wide range of size and performance options
- Custom crafted designs
Knowles' continues to drive the design and development of new microphone solutions for hearing aids. Developments include unidirectional, omni-directional, matched pairs, and combined uni-omni microphone designs. Behind-the-ear, in-the-ear,in-the-canal, completely in-the-canal, and new cochlear completely in-the-ear solutions are refined through variables such as shell size, RFI suppression, sound damping, port configuration, frequency response, shock resistance and more.
