IMPLANTABLE MICROPHONE DEVICE
First Claim
1. An implantable microphone device, said device comprising:
- a hermetically sealed housing having an internal cavity;
said internal cavity having a microphone assembly arranged to receive sound waves originating external from said housing; and
a pressure sensor arrangement, arranged to detect and determine the differential pressure between said internal cavity and the exterior of said housing;
wherein the determined differential pressure is for use in determining a suitable transfer function to be applied to the output of said microphone assembly to produce a signal representative of said received sound waves.

Abstract
An implantable microphone device is provided. The device comprises a hermetically sealed housing (3) having an internal cavity (2). The internal cavity (2) has a microphone assembly arranged to receive sound waves originating from external the housing (3). The device further comprises a pressure sensor arrangement, arranged to detect and determine the differential pressure between the internal cavity (2) and the exterior of the housing (3). The determined differential pressure is used to determine a suitable transfer function to be applied to the output of the microphone assembly to produce a signal representative of the received sound waves.
