Abstract
A hearing aid system is configured for managing the power of a wireless link. The hearing aid system includes a first hearing aid device and a mobile device, each of the devices including a transmit and receive unit for establishing a short range wireless link between the devices. At least one of the devices includes: a microphone configured to receive an acoustical audio signal; a signal processor configured to process an audio signal based on the acoustical audio signal; and first link quality estimating circuitry configured to determine rate of change of a link quality signal. The at least one of the devices is configured to transmit the link quality signal to the other device, and the other device is configured to determine a power level of transmission of an information packet based on the rate of change of the link quality signal via a power controller comprised by the other device.
