The task of Hearing and Speech lab is to research the perception of sound, mechanisms of normal hearing and hearing impairments, design and develop of signal processing algorithms for hearing aids and speech enhancement applications; implement of signal processing algorithms based on ultra-low DSP platform; design and specification of hearing devices. Our lab is now cooperated with Austar hearing science and technology Co., Ltd, and the only third-part algorithm and embedded software partner of ON Semiconductor in China. We have successfully developed adaptive wide dynamic range compression, adaptive directional microphone, active feedback cancellation, adaptive echo cancellation, oscillation detection, environmental noise reduction, impulsive noise reduction, wind noise reduction, frequency compression, spectrum contrast enhancement, and natural sound tinnitus masking algorithms.
