  • Patent number: 6047074
    Abstract: A digital hearing aid is employable for tinnitus therapy, as well as for retraining tinnitus therapy, in combination with correction of other hearing impairments of a user of the hearing aid. For this purpose, the hearing aid contains a signal processing chain, between a hearing aid input and a hearing aid output, which is responsible for producing a useful signal by acting on the input signal in a manner to correct the hearing impairment of a user of the hearing aid. The signal processing chain also includes an arrangement for generating a tinnitus therapy signal, which is combined in the signal processing chain with the useful signal, dependent on a mode of operation which has been selected or set.

  • Patent number: 5838806
    Abstract: In a method for processing data, in particular signal data in a programmable digital hearing aid, first a data memory is searched to locate a stored comparison input value corresponding with a current, incoming input data value E which satisfies a comparison condition. Subsequently the data memory is searched for a stored output value allocated in a predetermined manner now-identified to the stored input data value via a characteristic function. Subsequently the determined comparison output value is emitted as an output value, and the procedure is repeated for further incoming input data values. In a circuit for processing data, particularly signal data, in a programmable hearing aid, the incoming input data value is supplied via a data input/output unit of a processor to a comparison element for determining whether there exists a stored input value corresponding to the current input data value by satisfying a comparison condition.
