1. A companion microphone for a hearing aid, comprising:
- a microphone;
processing circuitry for producing an input signal from signals generated by the microphone;
a wireless radio transmitter for transmitting the input signal to a wireless receiver of the hearing aid;
an accelerometer;
a battery and power control circuitry; and
,wherein the processing circuitry is configured to adjust a radio transmission power level of the wireless transmitter in dependence upon signals generated by the accelerometer, wherein the radio transmission power level is reduced when accelerometer signals indicate that microphone is likely not in proximity to the user and the radio transmission power level is increased when accelerometer signals indicate the microphone is likely worn by the user.

Abstract
A hearing aid may utilize a companion microphone, separate from the hearing aid itself, for improving the understanding of speech spoken by a particular person or produced by a particular sound source. The companion microphone is a battery-powered hearing aid accessory device that picks up ambient sound and transmits corresponding radio signals to the hearing aid. Described herein are schemes help to preserve battery life in a companion microphone by using adaptive radio transmission power control.
