A 2.17mW Acoustic DSP Processor with CNN-FFT Accelerators for Intelligent Hearing Aided Devices

Applications of Artificial Intelligence in Hearing Aids and Auditory Implants: A Short Review

“…A recent paper on DNN in hearing aids was by Park et al [6a] where they found that the DNN could cancel noise by classifying the incoming noise based on its type, thereby providing better speech quality compared to normal hearing aid algorithms. Another article by Lee et al [7] compared two AI technology algorithms in hearing aids, one a DNN and another a convolution neural network (CNN). Their findings were that the CNN outperformed the DNN in terms of its speech enhancement strategy [7].…”

“…Another article by Lee et al [7] compared two AI technology algorithms in hearing aids, one a DNN and another a convolution neural network (CNN). Their findings were that the CNN outperformed the DNN in terms of its speech enhancement strategy [7]. There have been other works documenting the utility of DNN algorithms in separating speech and noise and allowing speech to be emphasised [18].…”

“…Current AI features are trainable hearing aids and own voice processing which enables automatic programming of a hearing aid based on the present environment. Future technologies include brain controlled hearing aids with the help of AI algorithms like DNN (deep neural network) and CNN (convoluted neural network) [7]. Details of AI or machine learning algorithms in hearing aids and implants are discussed below.…”
