Abstract: The current invention is intended to render artifacts, which are introduced by changes in coefficients in an FIR filter, inaudible by applying a window to the filtered signal that results in the output of the filter (e.g. FIR filter), in which the coefficients are being changed, supplying little or none of the total output while the output of the filter, in which the coefficients are stable, supplies most or all of the total output.

Abstract: Hearing aid systems where a data streaming device streams data to a hearing aid and methods of maintaining synchronization when converting a sampling rate are disclosed. A hearing system comprises a hearing aid, a sampling rate converter, a buffer, an RDWiff signal, and a control circuit. The hearing aid receives data from a data transmission device, and the data received has a first sampling rate. The sampling rate converter is in the hearing aid and converts the sampling rate of the received data to a sampling rate suitable for use by digital signal processing circuitry in the hearing aid. The buffer receives data from the sampling rate converter. The RWDiff signal indicates the difference between the rate at which data is read from and written to the buffer. The control circuit compares the RWDiff signal to a predetermined RWIdeal quantity and generates an adjustment signal.

Abstract: In devices using the present invention, audible artifacts may be reduced or eliminated by designing the system such that the sliding bias level is fed back to an output limiter so that a single algorithm manages all saturation artifacts. In embodiments of the invention, this feedback loop will eliminate the need for a second output limiter.

Abstract: Disclosed herein, among other things, are methods and apparatuses for integration of hearing aids with an MSD to improve intelligibility in noisy environments. One aspect of the present subject matter relates to a method of providing voice audio to a hearing aid or text in a hearing aid user's field of view, where the voice audio or text corresponds to a speaker of interest within a noisy environment, and where the speaker of interest is identified using smart glasses. An MSD graphical user interface is provided for a hearing aid user to identify a speaker of interest. The lip movement patterns of the speaker of interest are recorded by the smart glasses, and voice activity detection is performed on the lip movement patterns. Noise reduction is performed using the results of the voice activity detection. The noise-reduced voice audio may be transmitted to the hearing aid, or the speech recognition text may be transmitted to and displayed on the MSD.
