Testing Of Hearing Aids Patents (Class 381/60)
  • Patent number: 10412515
    Abstract: The present invention relates to recipient fitting of a hearing device. An embodiment of the present invention determines the transmission loss for sound applied to the recipient by the hearing device. Separate gains are then determined for compensating for the determined transmission loss and the measured hearing loss of the recipient. For example, in an embodiment, the hearing device may compensate for transmission losses in a 1:1 manner (i.e., the transmission loss in 100% compensated for). The hearing device may apply a different gain to compensate for the hearing loss, such as a gain that is a fraction (e.g., 33-55%) of the measured hearing loss.

  • Patent number: 10408671
    Abstract: Systems and methods are described that may provide audio information about an environment around a wearable device. Such audio information may be correlated with other biometric data to provide physiological information, e.g. regarding a wearer of the wearable device. For example, an illustrative method includes receiving an audio signal via a microphone of a wearable device and rectifying the audio signal with a peak detector. The method further includes amplifying the rectified signal with a logarithmic amplifier and causing an analog to digital converter (ADC) to sample the logarithmic signal. The method also includes causing the ADC to convert the sampled logarithmic signal to a digital output and storing the digital output in a memory of the wearable device. In some embodiments, the method includes transmitting the digital output to a computing device, which may correlate the digital output with other biometric data.

  • 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: 9578426
    Abstract: An analysis filter bank decomposes a microphone signal into sub-band signals, a gain unit applies a frequency-dependent gain to the sub-band signals, and a synthesis filter bank converts the amplified sub-band signals into a signal, which is then output by a receiver. A first adaptive filter of a feedback canceller provides feedback compensation signals adapted to compensate acoustic feedback from the receiver to the microphone, whereby the feedback compensation signals are subtracted from corresponding signals from the sub-band signals. A second adaptive filter of the feedback canceller estimates cross-frequency signal components resulting from aliasing of signal components from one sub-band into one or more neighboring sub-bands caused by non-ideal sub-band signal decomposition in the analysis filter bank with overlapping sub-bands. Thereby, the first adaptive filter is adapted in dependence of the estimated cross-frequency signal components.

  • Patent number: 9532146
    Abstract: Disclosed herein, among other things, are methods and apparatus for identifying one or more defective hearing aids. The present system provides a dichotic sound to the wearer that can be used to sense whether the aids are properly operating. Different types of dichotic sounds can be presented within the scope of the present subject matter. In various applications a Huggins pitch, a binaural edge pitch, a binaural coherence edge pitch, a Fourcin pitch or a dichotic repetition pitch is used for the dichotic sound. The pitch may be a pure-tone or complex-tone pitch. Various pure-tone frequencies and complex-tone fundamental frequencies may be used and may be customized for a particular application. In various applications, a dichotic sound is formed using left and right sounds each of which includes a noise and a desired signal component. The present system can be realized in a variety of implementations.

  • Patent number: 9491559
    Abstract: A method of acoustically fitting a hearing aid comprises providing a plurality of audible tones, each having a predetermined frequency through stereo headphones. The tones are provided at specific sound pressure in each ear. The patient changes the relative sound pressure in each ear until a perceived direction of source of the tone is in front of the patient. The amplification or attenuation requirements of a hearing aid are modified based on the difference in the sound pressures required for the left and right ears of the patient for perceived directional sameness for each frequency band-pass channel.

  • Patent number: 9479879
    Abstract: The present invention relates to recipient fitting of a hearing device. An embodiment of the present invention determines the transmission loss for sound applied to the recipient by the hearing device. Separate gains are then determined for compensating for the determined transmission loss and the measured hearing loss of the recipient. For example, in an embodiment, the hearing device may compensate for transmission losses in a 1:1 manner (i.e., the transmission loss in 100% compensated for). The hearing device may apply a different gain to compensate for the hearing loss, such as a gain that is a fraction (e.g., 33-55%) of the measured hearing loss.
