Abstract
In the European Union funded FACTS project the
development of Active Noise Control (ANC) systems for
vehicles utilising distributed actuators based on
ElectroMechanical Film (EMFi) technology was started. Two
car demonstrations were built, one for the "traditional"
active engine order noise control and one for the
attenuation of broad band noise radiation of the dash
panel, caused by the vibrations of the panel. Results
show that noise reduction using membrane mode EMFi
actuators is fully effective at higher engine orders (the
noise peaks are reduced to background noise level), when
the frequencies are above 200 Hz and the noise levels are
reasonable (below 80 dB). Also the broad band noise
radiation caused by the dash panel vibrations could be
attenuated some 5 dB in the frequency range 150 - 300 Hz,
but some amplification was present at higher frequencies
