摘要： The aim of the invention is to make using a hearing device and in particular a hearing aid more comfortable and more effective for the user. To this end the setting of a portable hearing device is to be checked. First the acoustic data of a sound from the environment of the hearing device is recorded and/or determined simultaneously with the setting of the hearing device with at least one setting value. The setting of the hearing device is evaluated against the chronologically matching, recorded acoustic data in the hearing device using at least one predeterminable criterion. If necessary, the hearing device outputs an appropriate message. By this means a hearing aid wearer can, for example, be alerted to contact an acoustician, if the settings he made on the hearing aid are not effective.

摘要： The output of signal tones from hearing aids for binaural coverage is to be synchronized. To this end, it is provided that the counters of the two hearing aids are equalized by a synchronization signal. By transmitting a control signal with a count value or before a predetermined count value, the simultaneous emission of a signal tone from the two hearing aids is initiated. Alternatively, for the indirect synchronization of the counters the respective differences of the counter readings may also be stored in the individual hearing aids.

摘要： Artifacts occurring during frequency compression, in particular in the case of hearing aids, are avoided or reduced. The method compresses the frequency of an audio signal having a fundamental frequency and at least one harmonic. The audio signal is provided in a plurality of frequency channels. The harmonic of the audio signal is shifted or mapped from a first frequency channel of the plurality of frequency channels into a second frequency channel. In addition a frequency which is likewise harmonic with respect to the fundamental frequency is estimated in the second frequency channel, the harmonic being shifted or mapped onto the estimated frequency. As a result the harmonic pattern is preserved in the compressed signal and the artifacts are reduced.

摘要： A method and device for frequency compression of audio signals to reduce the occurrence of artifacts. A component of the audio signal having a plurality of frequency channels is shifted from a first frequency channel into a second frequency channel. A dominant instantaneous frequency is determined in the first frequency channel. During shifting or mapping, first the entire first frequency channel, including the dominant instantaneous frequency, is shifted or mapped into the second frequency channel, wherein the dominant instantaneous frequency obtains an intermediate frequency position. A final frequency position for the dominant instantaneous frequency is determined using a predefined compression characteristic in the second frequency channel, starting from the frequency position of the dominant instantaneous frequency in the first frequency channel. Finally, the dominant instantaneous frequency is shifted or mapped from the intermediate frequency position to the final frequency position.

摘要： For hearing apparatus and especially for hearing devices a tone balance unit is to be able to be used even under difficult general conditions. Therefore a hearing apparatus with a signal processing device, through which signals are able to be processed in a number of frequency channels, and a control device for controlling the level of the individual frequency channels are provided. The setting device features an unsymmetrical tone balance unit related to a predetermined frequency with which at least one lower and at least one upper channel of the number of frequency channels related to a predetermined frequency is able to be simultaneously unsymmetrically adjusted relative to the predetermined frequency. Thus for example a tone balance unit can also be used with a low feedback limit in the upper frequency range.

摘要： A hearing apparatus and an associated method for suppressing feedback include a microphone emitting a microphone signal and a receiver picking up a receiver signal by subtracting a compensation signal from the microphone signal. The hearing apparatus includes a number of preset static first compensation filters for forming first compensation signals from the receiver signal and a first selection unit, which selects a first compensation signal in such a way that a feedback signal caused by the feedback is minimal in the receiver signal. An advantage thereof is that adaptation artifacts cannot occur.

摘要： A hearing aid device suitable for executing a frequency compression is optimized to achieve a better assignment between channels of a source frequency range and channels of a target frequency range. A frequency range that can be transmitted by the hearing aid device is split into a number of frequency bands, after which a number of adjacent frequency bands are combined into at least one group of frequency bands and then one frequency band is selected from each group of frequency bands. The selected frequency bands are moved respectively into a target frequency band permanently assigned to the respective group. This prevents that a number of frequency bands from the source frequency range are shifted to the same target frequency band.

摘要： A method for operating a hearing device, an associated microphone system comprising at least two omnidirectional microphones, and a hearing device are provided. The microphones emit microphone signals and are electrically interconnected with one another in order to form directional characteristics. A damping of the upper frequency range of the microphone signals is determined from the lower frequency range of the microphone signals. The impression of a wide-band directional microphone is produced as a result.
