Abstract: In a digital hearing aid device (1) frequency modification is employed above a lower spectral bound and in accordance with a compression factor. The frequency modification is dynamically adjusted in dependence on a sound environment analysis (10) or an end-user input (30), by modifying the frequency modification parameters such as a lower spectral bound and a compression factor. The adjustment can be based on an interpolation between predefined parameters. In certain sound environments, such as loud noise, own-voice and telephone conversations, frequency modification is reduced or switched off. The proposed solutions have the advantage that the occurrence of disturbing noise and of distortions of harmonic relationships at the end-user's ear is reduced and signal processing resources as well as battery resources are saved.

Abstract: The invention relates to a method for operating a hearing system comprising an input unit, an output unit and a transmission unit operationally interconnecting said input output units. Said transmission unit implements a transfer function describing, how audio signals generated by said input unit are processed in order to derive audio signals fed to said output unit, and can be adjusted by one or more transfer function parameters. Said method comprises obtaining, by means of said input unit and with a first directional characteristic, first audio signals from incoming acoustic sound; deriving from said first audio signals a first set of sound-characterizing data; and deriving, in dependence of first directional information, which is data comprising information on said first directional characteristic, and of said first set of sound-characterizing data, a value for each of said one or more transfer function parameters.

Abstract: The present invention relates to a method for recording information in a hearing device and/or in a recording unit at least temporally operationally connected to the hearing device. The method consists in that a point in time of the recording and/or a recording frequency as well as the information to be recorded, as data and/or parameters and/or adjustments of the hearing device are adjusted freely or are programmable, respectively. Furthermore, a hearing device is described that is suitable to use the method. By the present invention, a multitude of the parameters being adjustable in a hearing device can be checked or surveyed all together or selectively in real, i.e. actually existing acoustic environments in order to optimally adjust or adapt the hearing device afterwards, that means after the analysis by the fitter, for example.

Abstract: A hearing instrument in accordance with the invention comprises an in-the-ear-canal component to be worn at least partially in the ear of a user. When the hearing instrument is worn, a remaining volume between the in-the-ear-canal component and the user's eardrum is defined. The hearing instrument includes at least one first microphone operable to convert an acoustic input signal incident on the hearing instrument into an electrical input signal, signal processing means operable to convert the electrical input signal into an electrical output signal on a signal path, and an electrical-to-acoustic converter (a receiver or a plurality of receivers with potentially different frequency characteristics). Between the remaining volume and surrounding atmosphere, a duct (such as a vent) is defined. A second receiver is in operative communication with the duct, i.e. an output directly opens out into the duct or to a sound conductor opening out into the duct.

Abstract: A hearing system includes a hearing device with an input acoustical/electrical converter. The system is controllably operable in at least first and second modes. A sensing unit senses behavior of an acoustical impedance of an acoustical input of the input converter. An evaluation unit evaluates the sensed behavior over at least one predetermined behavior of the acoustical impedance. An output of the evaluation unit controls change over from the first mode to the second mode.

Abstract: In a signal processing unit of a hearing device, the signal processing unit consisting of a signal analyzing unit and a signal identification unit, the momentary acoustic surround situation is identified. Based on this identified surround situation, the parameter set belonging to the identified surround situation is automatically adjusted in a transmission unit in which a number of parameter sets are saved which are assigned to different acoustic surround situation. The hearing device user can adjust his individual hearing desire for each acoustic surround situation according to the automatic adjusted parameter set with the aid of an input unit. Thereby, the parameter of this parameter set are adjusted at the same time and commonly in one of two opposing directions, e.g. in the sense of “better hearing” or in the sense of “more pleasant understanding”.

Abstract: An adjustment method for a hearing device and an apparatus to do it are proposed, by which a model for the perception of a psycho-acoustic variable, especially of the loudness, is parametrized for a standard group of individuals (LN) as well as for an individual (LI). On grounds of model differences, especially in relation to their parametrization, the adjustment values are determined, whereas the signal transmission is planned or adjusted at a hearing device (HG) ex situ or is guided in situ, respectively.
