A novel system prevents surrounding sound to enter through a hearing apparatus, for instance through a ventilation opening, and reach an eardrum of the wearer in the form of interference sound. Contrary to auditory accessories designed especially to protect against noise, it is not possible for many hearing apparatus to compensate for such an interference sound by means of active noise cancellation. The hearing apparatuses do not have the special components needed. No compensation sound signal can therefore form with a correct phase. In accordance with the invention, a compensation sound is only generated for a relatively narrow spectral band. This spectral band is determined as a function of a hearing ability of the wearer of the hearing apparatus and/or as a function of a spectral distribution of the energy of the interference sound or a sound producing the interference sound. The improvement is particularly suited to compensating for an interference sound in a hearing device.

Wearers of hearing apparatuses and in particular of hearing device systems having two speakers are to be able to enjoy the experience of spatial multi-channel reproduction. Provision is accordingly made to generate a dual-channel audio signal for a binaural hearing apparatus comprising a multi-channel audio signal having at least three individual channels. Accordingly at least one spatial impression-influencing signal level in at least one of the individual channels is changed, and a signal of at least one of the individual channels is connected with signals of the remaining individual channels to the dual-channel audio signal. A corresponding hearing apparatus and in particular a corresponding hearing device have a transformation system that takes over this preprocessing from the multi-channel audio signal to the dual-channel audio signal.

A hearing apparatus to be worn on or in the ear is provided, which includes a housing. The housing is here formed at least in part from an electrochrome polymer. Since electrochrome polymers represent a homogeneous material, this means that they can be printed onto the housing in very thin layers. According to a second aspect the present invention relates to a hearing apparatus to be worn on or in the ear, including a housing, which has an organic light-emitting diode. Because organic light-emitting diodes are able to separate out light in a wide variety of colors, this permits a high contrast to the environment and the colors appear stronger. Unlike conventional light-emitting diodes this is however performed in a printing process, so that it is possible to provide any surfaces with organic light-emitting diodes.
