Abstract: A method operates a hearing aid system having a hearing instrument. An electro-acoustic input transducer of the hearing instrument generates an input signal from an acoustic signal from the environment, and an output signal is generated from the input signal by a signal processor. An output acoustic signal is generated from the output signal by an electro-acoustic output transducer of the hearing instrument. For at least one sub-process of the signal processing an artificial neural network is used which is implemented in the hearing instrument. A topology of the artificial neural network is defined and/or weights between individual neurons of the artificial neural network are selected according to an operation to be performed in the sub-process and/or according to an ambient situation and/or according to a user input by a user of the hearing aid system.

Abstract: 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.

Abstract: 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.

Abstract: A thin hearing tube is to be fastened in a hearing apparatus such that it can be easily exchanged again. To this end, the end of the sound tube is melted, so that its diameter is enlarged. The sound tube can then be drawn into the bore, the inner diameter of which is smaller than the enlarged outer diameter of the end of the sound tube, until the extended end of the sound tube rests closely against one side of the bore. By cutting the sound tube end or by cutting through the tube at another point, it can be removed from the bore without any problem, so that a new tube can be fastened there.

Abstract: 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.

Abstract: In acoustic systems, especially with hearing aids, feedback whistling keeps occurring. To avoid this, a limit gain frequency response of the amplification device, which represents the limits of feedback whistling, is thus recorded. On the basis of the curve recorded a required gain frequency response with a number of interpolation points is created, with each interpolation point having a predetermined minimum distance in each case to the limit gain frequency response in at least two different directions. This enables feedback whistling to be largely avoided, even with shifts in resonant frequencies.

Abstract: In order to improve spatial perception of acoustic signals an input signal is received via aid of a binaural hearing apparatus and optionally analyzed. At least one variable that influences spatial perception of the binaural output signal, based on the input signal, of the hearing apparatus will be changed. Thus, for example, the distance or direction of a source at/from which it is perceived can, with the aid of a classifier or directional microphone, be varied automatically for corresponding input signals, as a result of which improved spatial perception can be achieved.

Abstract: There is described a hearing device. A module is enabled to be easily attached to the casing of a hearing device, in particular a hearing aid. Toward that end a bridge is provided which has a drilled hole. A screw is inserted through a drilled hole in the module and screwed into the drilled hole of the bridge so that the module or, as the case may be, the closure of the opening is compressed onto the opening by means of the screw. Alternatively a cylindrical projection into which the screw is screwed can also be molded onto the inner wall of the casing.

Abstract: Adjusting a hearing device and thus also shaping the otoplastic or hearing device shell are to be optimized. Provision is made for this purpose to firstly geometrically measure a portion of the auditory canal, to extrapolate the remaining portion of the auditory canal and to produce a geometric model of the auditory canal based thereupon. An acoustic model of the auditory canal can then be determined using the geometric model, with account being taken in the acoustic model of the shape of the otoplastic or the hearing device. Finally the otoplastic or hearing device shell can be designed with the help of the geometric and the acoustic model. The hearing device can likewise be calibrated with the help of the acoustic model, which comprises the optimized otoplastic or hearing device shell.

Abstract: Method for amplifying an acoustic signal and corresponding acoustic system In acoustic systems, especially with hearing aids, feedback whistling keeps occurring. To avoid this, a limit gain frequency response of the amplification device, which represents the limits of feedback whistling, is thus recorded. On the basis of the curve recorded a required gain frequency response with a number of interpolation points is created, with each interpolation point having a predetermined minimum distance in each case to the limit gain frequency response in at least two different directions. This enables feedback whistling to be largely avoided, even with shifts in resonant frequencies.
