Abstract: Implantable microphone devices that may be utilized in hearing systems are provided. An implantable microphone device allows the implantable microphone's frequency response and sensitivity to be selected. A microphone device with an increased membrane flexibility and a decreased acoustic compliance of the sealed cavity. Vibrations of a membrane are transmitted through a primary air cavity and through an aperture of a microphone. Keeping a flexible membrane and decreasing the sealed air cavity compliance are the preferred way to simultaneously increase overall sensitivity of the device, and move the resonance peak to higher frequencies.
