Methods and systems for signal processing an audio signal in a hearing device to detect when feedback path change occurs and controlling an adaptive feedback canceler to remove the feedback are provided. The hearing device includes a receiver and a microphone. An exemplary method includes detecting whether a tonal signal is caused by a feedback path change by estimating a product of a subband error signal and a subband output signal generated in response to a subband audio input signal; estimating a fast metric based on the estimated product and estimating a slow metric; and applying or maintaining an adaptation rate to the adaptive feedback canceler of the hearing device, wherein the adaptation rate applied or maintained is selected based upon a value of the difference between the fast and slow metrics compared to a threshold value.

Detection of feedback path change

Systems and methods include an integrated circuit that includes a plurality of computing tiles, wherein each of the plurality of computing tiles includes: a matrix multiply accelerator, a computing processing circuit; and a flow scoreboard module; a local data buffer, wherein the plurality of computing tiles together define an intelligence processing array; a network-on-chip system comprising: a plurality of network-on-chip routers establishing a communication network among the plurality of computing tiles, wherein each network-on-chip router is in operable communication connection with at least one of the plurality of computing tiles and a distinct network-on-chip router of the plurality of network-on-chip routers; and an off-tile buffer that is arranged in remote communication with the plurality of computing tiles, wherein the off-tile buffer stores raw input data and/or data received from an upstream process or an upstream device.

In accordance with embodiments of the present disclosure, an adjustable equalization filter may have a response that generates an equalized source audio signal from a source audio signal to account for effects of changes in an electro-acoustical path of the source audio signal to a transducer. An equalizer coefficient control block may adapt the response of the adjustable equalization filter in response to changes in a response of a secondary path estimate filter for modeling the electro-acoustical path of a source audio signal through the transducer, wherein a response of the secondary path estimate filter is adapted in conformity with an error microphone signal indicative of the acoustic output of the transducer.

Accessing a circular buffer in memory from a processor may be performed with the aid of precomputed values stored in a pointer descriptor field of a processor storage element, such as a register. The pointer descriptor may store a precomputed value for calculating a memory address in the circular buffer, which may include two values, in which the two values are based, at least in part, on the size of the circular buffer, but neither be the size of the circular buffer. The first value may be used to derive a starting memory location for a circular buffer. The second value may be used in combination with the first value to calculate an end memory location. The start and end locations or addresses, along with the precomputed stored values, are then used to calculate the next address based on the current address of a circular buffer in an efficient manner.

A hearing aid includes electronics, a physically manipulable member, and a receiver. The receiver is configured to output sound in a first mode at a first decibel level and in a second mode at a second decibel level higher than the first decibel level. The first mode is based on an input from a microphone. The second mode is based on the physically manipulable member not having been manipulated over a selected period of time. In various examples, wireless approaches are used to perform location identification. Examples using antennas and radio frequency identification (RFID) are provided. Various location approaches are possible using different location tones and methods for generation of such tones. Other apparatus are provided for location identification in a system with one or more hearing aids.
