64 Bands Hybrid Noise Reduction and Feedback Cancellation Algorithm for Hearing Aid
Soon-Suck Jarng, Carl Swanson, Frank Lee, Joseph Zou · International Journal of Control and Automation · 2014
Both chronic problems of hearing aid have been solved by a probabilistic signal processing algorithm. The algorithm was implemented into a low and single voltage and low power dsp ic chip which can be used as a hybrid of the hearing aid. Both simulated and experimented results show clear noise reduction as well as feedback cancellation. The computational capacity of the physical chip was practically discussed for the limit of the algorithm.
