The performance of active noise controllers based on adaptive filters like the Filtered Reference Least Mean Square algorithm (FxLMS) is optimal in small zones around the error sensor locations. These locations provide the maximal possible reduction of noise but are not accessible by people due to the presence of the sensors. Virtual sensing algori...
As part of the bigger EU project MONICA (Horizon2020) a local quiet zone system is being developed. This system provides a zone of quiet close to loud outdoor concerts in order to support communications or minimize the noise exposure of staff. Because the noise sources are the loudspeakers of the venue’s PA system an ideal reference signal can be o...
