| 摘要 |
A bone anchored bone conduction hearing aid system comprising two separate microphones connected to two separate inputs of a hearing aid, and a microphone processing circuit in the electronic unit, processing the signals from the two microphones to increase the sound sensitivity for sound coming from the front compared to sound coming from the rear. One of the sound inlets being the frontal sound inlet which is positioned more in the frontal direction (F) than the other sound inlet. The bone anchored bone conduction hearing aid system of the present invention has a programmable microphone processing circuit where the sensitivity for sound coming from the front compared to sound coming from the rear can be varied by programming the circuit digitally in a programming circuit.
