Patent ID: 8885838

Claim:
A method of processing a signal in a hearing aid, comprising the steps of: picking up an acoustical signal; deriving an input signal from the acoustical signal; deriving a control signal from the input signal; and processing the input signal in a signal processing device by multiplying the input signal with a number derived from said control signal so as to provide an output signal, where the process of deriving said control signal comprises: estimating a signal level for the input signal hereby providing an input signal level estimate, executing a standard processing, including determining a standard control signal component in accordance with a standard compression characteristic, using the input signal level estimate as input to the standard compressor, executing an individualized processing, including determining an individualized control signal component in accordance with an individualized compression characteristic, using the input signal level estimate as input to the individualized compressor, executing an adaptive processing of the input signal using as input the standard control signal component so as to provide an adaptive control signal component, and multiplying the standard control signal component, the individualized control signal component and the adaptive control signal components to form the control signal, wherein the standard processing, the individualized processing and the adaptive processing are carried out in substantially the same frequency band.
