Abstract (en)
A method of adapting noise reduction when providing an audio signal and in particular in an environment, such as a vehicle, where the noise contents and noise level changes over time. The noise reducing signal and the audio signal are mixed, but in order to ensure optimum quality of the audio signal, the noise reducing signal is limited on the basis of a level/strength, so that at high audio signal level/strengths, the noise reducing signal is comparably lower than at lower levels/strengths of the audio signal.
