Abstract

Non-uniform frequency response of human hearing system requires conventional active noise control (ANC) system to be modified. Psychoacoustic active noise control (PANC) system based on filtered-E least-mean-square (FELMS) structure aims to improve the noise attenuation performance in terms of hearing perception. ITU-R 468 noise weighting reflects human hearing response to random noise. In this paper we incorporate ITU-R 468 noise weighting into PANC system. Sound quality analysis is conducted for attenuated noise with a predictive pleasantness model which combines four psychoacoustic parameters (loudness, sharpness, roughness and tonality). Simulation on realistic MRI acoustic noise shows improvement of sound quality in the new system.
