In order to investigate the problem of the active control of sound
transmission within the cabins of propeller-driven aircraft, a series of
experiments involving active control of sound transmission through a
clamped rectangular steel plate was conducted. The results, reported
here, show that it is possible to use active control forces to control
the transmission of sound through such a plate, ... [Show full abstract] both when the plate is
on-resonance and off-resonance.
