1. A hearing aid device configured to wirelessly communicate with a mobile device, wherein the hearing aid device comprises a transmit and receive unit for establishing a short-range wireless link between the hearing aid device and the mobile device, wherein the hearing aid device comprises:
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
at least one of
link quality determining circuitry configured to determine a link quality signal based on a position of the user wearing the hearing aid device;
a power controller configured to adjust a power level of transmission of an information packet between the hearing aid device and the mobile device based on a link quality signal determined by the mobile device and transmitted to the hearing aid device,
wherein a memory unit is included in at least one of the first hearing aid device, the mobile device, and a server connected to the hearing aid device or the mobile device,
wherein the memory unit stores a noise map correlating the position of the user wearing the hearing aid device with respective noise sources in the vicinity, and
wherein the link quality signal is determined based on the noise source(s) determined to be in the vicinity of the user, according to the memory unit, based on the position of the user.
