Active control of noise through open windows
Exploiting the Underdetermined System in Multichannel Active Noise Control for Open Windows
Active noise control (ANC) is a re-emerging technique to mitigate noise pollution. To reduce the noise power in large spaces, multiple channels are usually required, which complicates the
Physical Classification and Recent Developments of Active Noise Control Systems
The physical classification of the existing literature on the basis of both noise source and quiet zone characteristics is presented and examples are point to point, point to zone, zone to point and zone to zone.
Symmetric Design of Multiple-Channel Active Noise Control Systems for Open Windows
ABSTRACT There is a recent trend in deploying multiple-channel active noise control (MCANC) units to mitigate noise that propagates into urban accommodation through open windows, while preserving


Active Control of Low-Frequency Sound Radiation From Vibrating Panel Using Planar Sound Sources
Active control of low frequency sound radiation using planar secondary sources is theoretically investigated in this paper. The primary sound field originates from a vibrating panel and the planar
Basic Study on Active Acoustic Shielding
The AAS window is demonstrated to be able to attenuate not only normal incident sound but also oblique incident sound in the frequency range from 500Hz to 1.5 or 2kHz, and noise reduction is obtained over a wide area in the room.
Active Control of Sound
This book brings together results from research in the two disciplines of acoustics and signal processing and presents the fundamentals of noise control in a unified manner and focuses on algorithmic principles which form the foundation of practical systems.
