Abstract (en)
[origin: EP1919257A2] The method involves processing a signal at a hearing aid device (1), where the signal has a useful signal portion and a disturbance signal portion. The disturbance portion is reduced in favor of the useful portion, and the reduction of the disturbance portion takes place depending on an input level of the signal. The disturbance portion is strongly damped during a higher input level than a lower input level. The damping of the signal is canceled, when the input level or the disturbance portion of the input level falls below a preset lower threshold value due to further damping of the signal. An independent claim is also included for a noise reduction device for a hearing aid device.
