Abstract

The disclosure relates to a method of audio processing in a hearing device to provide for a gain adjustment, the method comprising receiving an audio signal (SI) from an audio input unit (117); processing the audio signal (SI) in a first path (P1) and a second path (P2), wherein each path (P1, P2) is associated with detecting a signal level of the audio signal (SI) for applying a gain adjustment to the audio signal (SI) depending on the signal level, and wherein the processing in the first path (P1) is adapting faster to changes of the signal level than the processing in the second path (P2); generating a mixed signal (SM) by mixing the audio signal processed in the first path (P1) and the audio signal processed in the second path (P2) in accordance with a mixing ratio; and providing an output signal (SO) based on the mixed signal (SM) for an audio output unit (117) configured to output the output signal (SO). To provide for an improved gain adjustment, e.g., with regard to the responsiveness and/or stability, the disclosure proposes estimating a noise floor (313, 614) of the audio signal (SI); and determining the mixing ratio depending on the noise floor (313, 614).
