Abstract: A listening device comprises a device housing (10,40) worn in the ear, a device housing (20,25) worn outside the ear and an electronic circuit which is divided over the two device housings (10,20). The first device housing comprises an electro-acoustic converter (13) and a first microphone (11). The electronic circuit comprises at least one further microphone (12,21,22). A signal processing device (23) comprises at least one signal input to which the first microphone (11) and the at least one further microphone (12,21,22) are electronically coupled so as to generate a microphone signal thereto. The electro-acoustic converter (13) is connected to a signal output of the processing device (13) which is at least loadable with a processing algorithm and is thus able and configured to calculate and present the output signal as algorithmic resultant of at least the microphone signals from the first microphone (11) and the at least one further microphone (12,21,22).

Abstract: A hearing aid comprises a microphone on a proximal side of a device housing and a loudspeaker which via a transmission channel is in open communication with a sound-emitting opening of the device. A sound processing device serves to generate sound received by the microphone to the loudspeaker in amplified form. The device housing is provided on a distal side with an optionally sealed battery chamber for receiving a battery therein. The transmission channel is at least almost wholly separated from the microphone acoustically in order to prevent acoustic feedback. The battery chamber comprises ventilation means for the purpose of increasing the lifespan of the battery.

Abstract: A hearing aid includes a device housing to be worn outside an ear of a user and which co-acts with an in-the-ear part provided with a sound-emitting opening and which is intended and adapted to be received at least substantially in the ear of the user. The in-the-ear part is physically separated from the device housing, wherein at least a microphone and a loudspeaker are accommodated together with the sound-emitting opening in the in-the-ear part. An electronic connection is present between the device housing and the in-the-ear part. A power supply of a hearing aid particularly includes a capacitor (40), more particularly an ultra-capacitor. The functionality of a hearing aid can be expanded with an expansion unit (50). For an accurate fit of the in-the-ear part use is made of a digital representation which has been modified on the basis of fitting data of a fitting body.

Abstract: A sound reproduction system includes an audio source (10) for generating an electronic audio signal which is coupled via a sound processing device (2) to reproducing elements (30) which are able and adapted to (re)produce sound in accordance with a reproduction characteristic. Programming elements (40) are able and adapted to receive an optionally frequency-dependent pre-correction, this pre-correction being able and adapted to at least partly compensate for a difference between at least one or more parts of the reproduction characteristic and a reference characteristic taken for comparison purposes, and to renew a processing characteristic on the basis of the thus obtained pre-correction. The pre-correction can be accessed separately of the reproducing elements.
