Abstract

This paper provides analysis and real-time performance comparisons on modified application from two-microphone classic adaptive noise cancelling and beamforming methods. Experiments are processed by software implementation using LabVIEW in a real environment, which is typical indoor office with moderate reverberation condition. The speech performances are analyzed in time and frequency domains using both stationary and nonstationary noises. The analysis on the three type of microphones configuration and computational complexity on NLMS algorithm and TDOA function have also been investigated, which could give rise to insight and interests for hardware prototype implementation of digital adaptive hearing aids.
