ABSTRACT
The transducer developed was tested as a sound control element in the integrated system for active noise control at Virginia Polytechnic Institute (Christopher Fuller). Six independently controlled PANELS were mounted over the vibrating aluminum plate forming an effective active skin. The adaptive feed forward Filters-x Least-Mean-Square (LMS) Algorithm was employed in the six input, six output control scheme. Far field microphones were used for each of the six error sensors, while ten additional far field microphones enabled estimation of the sound power radiated before and after the implementation of control. Experiments revealed that attenuation of more than 10 dB is attainable over the frequency range of interest.
