Experiments on the active reduction of sound transmission through light-weight constructions
Experiments have been performed to study the active reduction of sound transmission through single and double gypsum board constructions. The active control scheme was based on the feedforward and feedback control strategies. The electromechanical film flat panel actuators were tested. These actuators attached to the radiating surface of the lightweight partition can significantly reduce the sound transmission. The active systems achieves 2 - 9 dB reduction of the average sound intensity level over the controlled surface of the radiating wall for random noise excitation in the frequency range from 100 to 400 Hz.
