There is provided a method for providing hearing assistance to a user, comprising: capturing audio signals by a microphone arrangement (17) of a transmission unit (10, 1 10); analyzing, by a voice activity detector (24) of the transmission unit, the captured audio signals in order to judge whether a voice is present close to the microphone arrangement or not, analyzing, by a noise level estimator (25), the captured audio signals in order to estimate a surrounding noise level, processing the captured audio signals and transmitting, by a transceiver (28) of the transmission unit, the processed audio signals via a wireless link (12) to a receiver unit (14, 1 14, 214), and stimulating the user's hearing, by stimulating means (16, 64, 82, 182) worn at or in at least one of the user's ears, according to the received audio signals, wherein the audio signals are processed prior to and/or after transmission via the wireless link by setting the gain applied to the audio signals according to the close voice / no close judgement of the voice activity detector and the estimated surrounding noise level, wherein said gain is set to a first gain value (g1) during times when the presence of close voice is judged, wherein said gain is reduced from the first gain value by an attenuation value (a) to a second gain value (g2) when a change from close voice to no close voice is judged, and wherein the attenuation value is selected as a function of the estimated surrounding noise level in such a manner that the attenuation value increases with increasing estimated surrounding noise level. |
