Experimental determination of the particle motions associated with the low order acoustic modes in enclosures [PDF]
A procedure for experimentally determining, in terms of the particle motions, the shapes of the low order acoustic modes in enclosures is described. The procedure is based on finding differentiable functions which approximate the shape functions of the ...

Structural-acoustic coupling and psychophysical effects in the active control of noise in vehicles
, 2011 Active noise control systems offer a potential method of reducing the weight of passive acoustic treatment and, therefore, increasing vehicles' fuel efficiency. These can be particularly cost-efficient if integrated with the entertainment system.
