Testing Of Hearing Aids Patents (Class 381/60)
  • Patent number: 10887713
    Abstract: Disclosed are an apparatus and method for testing a microphone of a device under test. The apparatus includes a speaker, a mount or bracket that secures a device under test a fixed distance from the speaker, and a controller. The controller causes the speaker to generate a test signal at various amplitudes. The controller receives an output signal generated by the microphone in response to the test signal and generates a prediction of whether the microphone is defective based on the output signal. The prediction may be generated by a machine-learning model such as a neural network or other trained classifier.

  • Patent number: 10009704
    Abstract: Techniques of performing binaural rendering involve separating symmetric and antisymmetric terms in the total output rendered in the ears of a listener. Along these lines, a sound field includes a set of sound field weights corresponding to spherical harmonic (SH) functions in a SH expansion of the sound field. In addition, an aggregate head-related transfer function (HRTF) includes a set of HRTF weights that correspond to a SH function. An HRTF weight may be generated from aggregating products of an HRTF at each of a set of loudspeaker positions and a SH function to which the HRTF weight corresponds at that loudspeaker position. The rendered sound field in one of the ears of the listener would be, when the sound field and HRTF is a function of frequency, a sum of the products of corresponding sound field weights and HRTF weights. One may save much computation by grouping the products into symmetric terms and antisymmetric terms.

  • Patent number: 10003906
    Abstract: A device for determining room-optimized transfer functions for a listening room serving for room-optimized post-processing of audio signals in spatial production, is configured to analyze room acoustics of the listening room and to determine, based on the analysis of the room acoustics, the room-optimized transfer functions for the listening room where the spatial reproduction by means of a binaural close-range sound transducer is to take place. The spatial reproduction of the audio signals by means of the binaural close-range sound transducer may then be emulated using known head-related transfer functions und using the room-optimized transfer functions, wherein a room to be synthesized may be emulated based on the head-related transfer functions, and wherein the listening room may be emulated based on the room-optimized transfer functions.

  • Patent number: 9967680
    Abstract: Disclosed herein is a feedback reduction system for used in a hearing prosthesis. The hearing prosthesis will receive an input signal, process the input signal, and create a transformed output. However, the hearing prosthesis may suffer from feedback. Thus, a system to minimize the feedback in a hearing prosthesis may be desirable. One system to minimize the feedback includes down-sample circuitry configured to down-sample a first signal, creating a down-sampled signal. They system also includes a filter circuit. The filter circuit filters both the first signal and the down-sampled signal. The filter will output a filtered signal and a filtered down-sampled signal, respectively. Additionally, the system features up-sample circuitry that up-samples the filtered down-sampled signal. The output of the up-sample circuitry is an up-sampled signal. Further, the system features combining circuitry that creates a feedback-reduced signal based on the up-sampled signal, the filtered signal, and an input signal.
