Adaptive feedback cancellation in hearing devices
The patent US12010486B2 outlines a method for processing audio signals in hearing devices to detect changes in feedback paths. The method involves detecting whether a tonal signal is indicative of feedback onset by estimating a product of a subband error signal and a subband output signal derived from a subband audio input signal. A metric is then estimated based on this product, and feedback path changes are identified when this metric meets or exceeds a predetermined threshold. The method also includes the estimation of both fast and slow metrics, with the difference between them being used to inform the adaptation rate of an adaptive feedback canceler within the hearing device.
Additionally, the patent describes how the processor in the hearing device is responsible for performing these estimations and detections. It specifies that the adaptation rate can be adjusted based on the detected feedback conditions, applying a faster rate when feedback is detected and a slower rate when it is not. The method allows for the processing of audio signals across multiple subbands, enhancing the device's ability to manage feedback effectively. Overall, the claims detail a systematic approach to improving the performance of hearing devices in the presence of feedback, ensuring a better auditory experience for users.
