Abstract: Method for providing hearing assistance to a user by capturing audio signals with a microphone arrangement of a transmission unit; analyzing, by a voice activity detector of the transmission unit, the captured audio signals to judge whether a voice is present close to the microphone arrangement or not, analyzing, by a noise level estimator, the captured audio signals to estimate a surrounding noise level, processing the captured audio signals and transmitting, by a transceiver of the transmission unit, the processed audio signals via a wireless link to a receiver unit, and stimulating the user's hearing, by stimulating means at or in at least one user ear, according to the received audio signals, wherein the audio signals are processed via the wireless link by setting the gain applied to the audio signals according to the close voice/no close voice judgment of the voice activity detector and the estimated surrounding noise level.
