Abstract
A hearing aid is enabled for dynamic compression in a way to further improve the perception of acoustic signals in the provision of hearing assistance to a hearing-impaired person. Here, an input signal is divided into a plurality of frequency bands. Input-level-controlled dynamic compression is performed in at least one first frequency band and output-level-controlled dynamic compression is performed in at least one second frequency band. This optimizes both loudness perception and speech intelligibility.
