Local sensing/control or global error sensing/control in structural acoustics: A comparison of two techniques influence over sound power
SG Hill, N Tanaka, H Iwamoto - Applied acoustics, 2010 - Elsevier
The active control of radiation from large structures is a difficult, though important practical
problem. The major reason for the difficulty is the 'system'size, as a large number of sensors …
