Abstract: The invention relates to a method for processing an acoustic input signal, preferably a speech signal, said method comprising the following steps: a) receiving a digital representation (Sin) of an acoustic input signal, b) calculating at least one statistical parameter (P) of the digital representation (Sin) of the acoustic input signal, c) calculating a compression ratio function (CRf) based—on a prescribed constant compression ratio (CRpr), said prescribed constant compression ratio (CRpr) uniformly mapping acoustic input signals of a selected magnitude to acoustic output signals of a selected magnitude, and—on at least one statistical parameter (P) calculated in step b), and d) applying the non-uniform compression ratio function (CRf) according to step c) on the digital representation (Sin) of the acoustic input signal delivering a digital representation (Sout) of an enhanced acoustic output signal.

Abstract: A communication system comprises a transmitter unit (10, 60) arranged to be carried by or located near a user, and an earpiece including a receiver unit (30, 70), the system operating with a carrier frequency of less than 100 kHz, preferably less than 30 kHz, most preferably in the range 14 to 20 kHz. The system employs vestigial sideband modulation by cutting off part of an upper sideband. The received signal is digitized and then sampled to an envelope-tracking sampled-data root-filter square detector (40) configured as a digital signal processor.

Abstract: The invention relates to system and method for configuring a hearing device (100) with an external configuration unit (101), the method comprising the steps of: a) processing at least two sound recordings in the external processing unit (104?) with different parameter settings (105?a, 105?b), b) combining them into one joint signal, c) feeding the joint signal to the hearing device's output transducer (107), bypassing the rest of the hearing device (100), d) emitting the joint signal, e) letting the user (111) choose one of the sound recordings that fits his/her requirements best, f) repeating steps a) to e) with varying parameter settings, g) transmitting a chosen parameter setting to the hearing device (100), wherein in step a) the sound recordings to be processed are chosen according to the situation the hearing device (100) will be used for or the specific hearing impairment of a user (111) of the hearing device (100).
