Low Delay Noise Reduction and Dereverberation for Hearing Aids

A new system for single-channel speech enhancement is proposed which achieves a joint suppression of late reverberant speech and background noise with a low signal delay and low computational complexity. It is based on a generalized spectral subtraction rule which depends on the variances of the late reverberant speech and background noise. The calculation of the spectral variances of the late ...

A novel low-voltage low-power wave digital filter bank for an intelligent noise reduction digital hearing instrument

We propose an acoustic noise suppression system embodying a novel low-voltage low-power multiplexed 16-channel lattice wave digital filter bank (LWDFB) for an intelligent digital hearing instrument. This system alleviates the intensity of computation problem and eliminates the delay problem of FFT-1FFT-based systems. To satisfy the tight constraints of low voltage, low power and a small IC area...
