摘要:
Monitoring usage of a hearing device includes: c) checking whether a message has been received within a time period (dt) shorter than a pre-defined time period (Dt) via a long-distance communication network in a remote device; and d) generating usage status data dependent on the result of the checking addressed in step c). The usage status data are indicative of the usage of the hearing device, indicating “use” if the time period (dt) is smaller than or equal to the pre-defined time period (Dt) and indicating “non-use” if the time period (dt) is larger than the pre-defined time period (Dt). The message includes identification data for identifying the hearing device or a user of said hearing device. The remote device is located remote from the hearing device and connected to the long-distance communication network. The time period (dt) starts from a start event.

The present invention is directed to a method and a hearing device for extending a usable frequency range of an analog input signal (i) being processed by a hearing device, the method comprising the steps of converting the analog input signal (i) to a first output signal (o1) and to an intermediate signal (om), the first output signal (o1) having a final sampling rate and the intermediate signal (om) having an intermediate sampling rate that is greater than the final sampling rate, applying a band-pass filter unit (31) to the intermediate signal (om) in order to obtain a filtered intermediate signal (omf), a lower cut-off frequency of the band-pass filter unit (31) being above half the final sampling rate, an upper cut-off frequency of the band-pass filter unit (31) being below half the intermediate sampling rate, and shifting a spectrum of the filtered intermediate signal (omf) to a frequency range being below the final sampling rate to obtain an intermediate output signal (om2).

A binaural hearing device system comprises a reception device (1) for one ear with at least two input acoustical/electrical converters (3a, 3b). Via a communication link (5) a signal (A1) which depends on both input converter's output signals is transmitted to a second device (7) for the other ear which comprises at least an output electrical/mechanical converter.

In order to switch between different hearing programs to adjust to a momentary acoustic surround situation, a method is provided to operate a hearing device as well as a hearing device. Signals, or parameters of a transfer function, are changed smoothly in order to form a smooth transition from a momentary to a desired value. Thereby, the advantage is obtained to eliminate undesired abrupt switching operation when a hearing program switching is necessary.

摘要:
In a process for filtering interfering signals, occurring with largely known constant repetition frequency at the use of hearing devices in or at the hearing device the repetition frequency of the interference signal shall be detected and at recognition of the known constant frequency the signal shall be suppressed or damped respectively at the expected next point of time at least partially. The detection can happen for instance via the duty cycle and/or the basic frequency of the interference signal.
摘要:
A method is described to operate a hearing device with an input transducer (1), a signal processing unit (2) and an output transducer (4). The method comprises the steps of converting an acoustic input signal into a converted input signal, processing the converted input signal in a main signal path in order to obtain a main output signal, and supplying the main output signal to an output transducer. By processing the converted input signal in a side signal path to obtain a side path output signal, and by superimposing the side path output signal on the main output signal, wherein a group delay of a signal traveling through the side signal path is smaller than a group delay of a signal traveling through the main signal path, the localization problems are eliminated. At the same time, the hearing device according to the present invention can still have a very high performance. In short terms, a “zero-delay-high-performance” hearing device has been created by the present invention.

The hearing device system comprising at least one hearing device comprises an input transducer for receiving incoming acoustical sound and converting said incoming acoustical sound into audio-representing signals; an output transducer for converting audio-representing signals obtained from said incoming acoustical sound into signals to be perceived by a user of the hearing device; and a transmitter for transmitting audio-representing signals obtained from said incoming acoustical sound to a long-range communication network. The method for maintaining a hearing device system comprises the steps of receiving in the hearing device an incoming acoustical sound; converting in the hearing device said incoming acoustical sound into audio-representing signals; and transmitting said audio-representing signals from the hearing device to a long-range communication network. Said audio-representing signals may be received by a hearing device support provider.
