| Research Abstract |
This study aimed to reduce noise from the system inside combining microphones and piezoelectric devices, and contactless noise reduction system by replacing piezoelectric devices to laser listening devices. This study also aimed single channel noise reduction using cross TF ε-filter and a blind separation of monaural sound based on peak tracking of frequency spectra. Parameter settings based on signal-noise de-correlation and recognition system were also proposed.
