In this paper we present a new psychoacoustic active noise control system based on delayless subband adaptive filtering structure. Human hearing has selective sensitivity for different frequency bands. Motivated by this psychoacoustic fact, noise weighting is incorporated into active noise control system. In this new system, the noise weighting is decomposed into subband forms for computation efficiency...
Conventional adaptive active noise control (ANC) methods aim to attenuate the acoustic noise over the frequency band of interest indiscriminately using the sound pressure level (SPL) measurement (or the measurement of the residual error variance). However, SPL does not correctly reflect the human perception of attenuated noise due to the frequency selective sensitivity of human hearing system. A-weighting...
