A hearing aid microphone assembly is configured for implantation into a subject and includes a microphone housing, the housing having a generally conical sound gathering portion with a proximal end and a distal end and a microphone support portion with one or more ports configured to receive a microphone and acoustically coupled to the distal end. A diaphragm is disposed over the proximal end of the housing to hermetically seal the sound gathering portion of the housing and create a first chamber. The microphone assembly is configured with either: (1) at least a first and a second port each coupled to a microphone; or (2) at least a first port coupled to a microphone and an accelerometer coupled to the housing. Each of the ports is configured to communicate acoustically with the first chamber. Any unused ports are sealed. |
