Abstract

The present invention relates to a hearing instrument which comprises a microphone comprising a microphone transducer element mounted in a microphone housing. The microphone transducer element produces a transducer signal in response to receipt of sound and a microphone amplification circuit is configured to generate an amplified microphone signal from the transducer signal. A control and processing circuit of the hearing instrument is coupled to the microphone amplification circuit for receipt and processing of the amplified microphone signal according to a hearing loss of a user. The microphone amplification circuit has a power supply port coupled to a switchable power supply which is selectively connected to a first power supply voltage, having a first DC voltage level, or a second power supply voltage, having a second DC voltage level, to the power supply port of the microphone amplification circuit. The second DC voltage level is higher than the first DC voltage level. A level detector is configured to detect a level of a microphone signal and connect the first or the second power supply voltage to the power supply port based on the detected level of the microphone signal.
