Abstract

The acoustic signals are amplified by transformation of signals which are not audible to the hard of hearing into the audible range in such a manner that the apparent loudness during the listening is equal in persons with normal hearing and in persons who are hard of hearing. The device contains an analysis section with a stage (5) for loudness estimation, with a stage (10) for individual adaptation to a person hard of hearing and with a stage (11) for determining the gain factors (G1...n). <IMAGE>
