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.
