    摘要: A hearing aid system is provided that facilitates adjustment of signal processing parameters θ of the hearing aid system with minimum user intervention, wherein the hearing aid system is capable of calculating signal processing parameters θ for evaluation of the user when the user has entered an input, e.g. using a smartwatch, to this effect. The evaluation takes place for a certain time period and in the event that the user has entered a consent input indicating that he or she is pleased with the set θ of signal processing parameters under evaluation, the hearing aid system continues processing with those signal processing parameters; and if the user is not pleased with the signal processing parameters θ under evaluation, the hearing aid system calculates another set {circumflex over (θ)} of signal processing parameters for evaluation of the user.

    摘要: An example of an apparatus configured to be worn by a person who has an ear and an ear canal includes a first microphone adapted to be worn about the ear of the person, and a second microphone adapted to be worn at a different location than the first microphone. The apparatus includes a sound processor adapted to process signals from the first microphone to produce a processed sound signal, a receiver adapted to convert the processed sound signal into an audible signal to the wearer of the hearing assistance device, and a voice detector to detect the voice of the wearer. The voice detector includes an adaptive filter to receive signals from the first microphone and the second microphone.

    摘要: The application relates to a filter bank for an audio processing device, e.g. a hearing aid. The filter bank comprises an analysis filter bank comprising a plurality of M first filters hm(n), where m=0, 1, . . . , M−1 is a frequency band index, n being a time index, the first filters hm(n) having a first filter length of Lhm; a synthesis filter bank comprising a plurality of M second filters gm(n), m=0, 1, . . . , M−1, the second filters gm(n) having second filter lengths of Lgm; the plurality of first and second filters being arranged in pairs, each pair forming a frequency channel. the first filters hm(n) exhibiting a first filter delay τh, the second filters gm(n) exhibiting a second filter delay τg, each of the first filter lengths Lhm and the second filter lengths Lgm is uneven, and wherein the first filters are subject to the constraint that the sum of the first filters hm(n) of the analysis filter bank is a delta function δ(n−τh).

    摘要: Processing digitized microphone signal data in order to detect wind noise. A first signal and a second signal are obtained from at least one microphone. The first and second signals reflect a common acoustic input, and are either temporally distinct or spatially distinct, or both. The first signal is processed to determine a first distribution of the samples of the first signal. The second signal is processed to determine a second distribution of the samples of the second signal. A difference between the first distribution and the second distribution is calculated. If the difference exceeds a detection threshold, an indication is output that wind noise is present.
