Claim Text:
1. A hearing device comprising: a microphone for converting audio into an audio signal; a preprocessing unit for analog processing of the audio signal, wherein the preprocessing unit is coupled to the microphone; an A/D converter for converting the processed analog audio signal into a digital audio signal, wherein the A/D converter is coupled to the preprocessing unit; and a processing unit for digital processing of an output from the A/D converter, wherein the processing unit is coupled to the preprocessing unit; wherein the preprocessing unit is configured to apply a first transfer function to the audio signal in a first mode of operation, or a second transfer function with a cutoff frequency to the audio signal in a second mode of operation, depending on a control signal from the processing unit; and wherein the processing unit comprises a detector unit configured to determine one or more noise parameter(s), and wherein the processing unit is configured to send the control signal indicative of the first or second mode of operation to the preprocessing unit based on the one or more noise parameter(s).
