Abstract: A field ready, unsupervised-use ready, method and apparatus for audio fittin g a hearing aid is described in a hand held configuration having paired comparison (hearing selections) stored in and derivable from a memory therei n. The paired comparisons are presented one at a time to a user and a preferred selection for each paired comparison is made by a select indicator after the user toggles back and forth between the selections for as many times necessa ry in determining their preferences. A genetic algorithm converges all the preferences upon a single solution. Crossover and mutation genetic algorithm operators operate on a linear range of indexes representative of parametric values of the pairs. A fully integrated hearing aid having all the above described features incorporated therein is also presented.

Abstract: A system for measuring speech content in sound. The system determining time local speech-to-noise ratio for one or more bands. The system using a signal related to the power of the input signal or envelope and generating a time-dependent mean of the envelope and deviation of the envelope from the mean to estimate a time-dependent speech-to-noise ratio. The system providing single band or multiband speech-to-noise estimates for signal processing applications. The system realizable in analog, digital or analog and digital combinations.

Abstract: Systems, devices, and methods are provided to inhibit apparent amplitude modulation in non-linear processing that causes distortion in a processed signal. One aspect of the invention includes a hearing aid. The hearing aid includes a microphone to receive an input signal, a speaker to reproduce the input signal, and a processor. The processor processes the input signal usin g a gain. The processor includes an inhibitor, which inhibits distortions, and an adjuster, which adjusts the gain. The inhibitor acts to smooth en envelop e of the input signal to inhibit undesired modulation. The adjuster adjusts th e gain if the envelope is either above or below a threshold. The hearing aid further includes a compression recapture system to supply the compressed portion of the input signal to more closely reproduce the actual input signa l.

Abstract: Systems, devices, and methods are provided to inhibit at least one feedback component of an input audio signal by adjusting a feedback-inhibiting filter through a high signal-to-noise subaudible signal. The level of the signal ma y be determined using an audibility model so as to yield its subaudible qualit y.

Abstract: Disclosed herein, among other things, are apparatus and methods for annoyance perception and modeling for hearing-impaired listeners. One aspect of the present subject matter includes a method for improving noise cancellation for a wearer of a hearing assistance device having an adaptive filter. In various embodiments, the method includes calculating an annoyance measure or other perceptual measure based on a residual signal in an ear of the wearer, the wearer's hearing loss, and the wearer's preference. A spectral weighting function is estimated based on a ratio of the annoyance measure or other perceptual measure and spectral energy. The spectral weighting function is incorporated into a cost function for an update of the adaptive filter. The method includes minimizing the annoyance or other perceptual measure based cost function to achieve perceptually motivated adaptive noise cancellation, in various embodiments.
