The disclosure concerns a system for actively cancelling an acoustic noise signal entering through an aperture of a room. The system includes a sensor to detect the acoustic noise signal and convert it into an electronic noise signal; a plurality of transducers to generate an acoustic anti-noise signal from an electronic anti-noise signal to cancel...
The push for greater urban sustainability has increased the urgency of the search for noise mitigation solutions that allow for natural ventilation into buildings. Although a viable active noise control (ANC) solution with up to 10 dB of global attenuation between 100 Hz and 1000 Hz was previously developed for an open window, it had limited low-fr...
In this paper, we evaluate different development platforms for implementing a multi-channel active noise control system. The main motivation in doing so is to find out how different processing platforms can be used to quickly prototype ANC solutions; their ease of programming; provide a reference design to build an embedded system that can be deplo...
Commercial noise-cancelation headphones are based on active noise control (ANC) algorithm. However, all existing ANC headphones are based on bilateral ANC approach, where two independent monaural ANC systems are used respectively for the left and the right ear cups. The performance of bilateral ANC approach strictly depends on the number of noise s...
Active noise control (ANC) algorithm is widely deployed in noise cancelling headphones. However, most ANC algorithms still use noise energy reduction to control its adaptive filter and neglect the psychoacoustic aspect in controlling filter that better suit human hearing. In addition, ANC algorithm is usually applied to each side of the ear cup ind...
The active noise control (ANC) algorithms are widely applied in noise-canceling headphones. However,
the disadvantage of conventional ANC algorithms is the high computational cost from high order
finite-impulse-response filter, which also leads to slower convergence. Subband ANC algorithms, which
are based on the subband adaptive filter, are used t...
The active noise control (ANC) algorithm is widely
used nowadays for different applications and areas. However,
problem with conventional ANC algorithm is the high
computational cost for high order FIR filter that is required for
better broadband noise attenuation performance. Subband ANC
algorithms, which are based on the subband adaptive filter,...
