Lightweight, high insertion loss, active noise enclosure with air gaps. Journal of the Acoustical Society of America, 97(3), 1983-1986. doi: 10.1121/1.4120100001-4966http://hdl.handle.net/10919/52683Preliminary experiments that demonstrate the control of noise using a lightweight, active enclosure with significant air gaps are discussed. The active enclosure consists of a lightweight, plexiglass box with piezoceramic actuators bonded to each side as active inputs. The control approach used is the filtered-x LMS. Global reductions of 7 to 20 dB are reported and mechanisms of control are discussed. ï¿_ï¿_ï¿_ 1995 Acoustical Society of America4 pagesapplication/pdfen-USIn CopyrightActive noise controlLightweight, high insertion loss, active noise enclosure with air gapsArticle - Refereedhttp://scitation.aip.org/content/asa/journal/jasa/97/3/10.1121/1.412010Journal of the Acoustical Society of Americahttps://doi.org/10.1121/1.412010
