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 narrowband subaudible signal. The level of the signal may be determined using an audibility model so as to yield its subaudible quality.

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.
