Feedforward Headphone Active Noise Control Utilizing Auditory Masking

A novel adaptive Active Noise Control approach for headphones is presented in this work. The proposed method achieves a reduction in the perceived noise-disturbance and thus makes the presented stimuli more acceptable to the listeners. The ANC operates by extracting auditory masking thresholds based on the signal the user intends to listen to, i.e., music, and subsequently designing a time-domain parallel infinite impulse response filter bank by employing a novel system identification strategy, making the proposed method ideal for SoC implementation. A subjective listening test and an objectivemetric are utilized to assess the perceived improvement of themethod and a statistical analysis is performed on the results in order to showthe advantage of the proposedANCmethod compared to traditional approaches in terms of perceived increase in audio quality.
