SOUNDPROOFING APPARATUS AND METHOD UTIILIZING AN ACTIVE SOUND FIELD CONTROL DEVICE AND A SOLAR HEAT COLLECTOR

摘要

PURPOSE: Environmentally-friendly soundproof wall technology is provided to reduce a wide band of noises through combined use of an adaptive sound field control soundproof device and a solar energy current collector. CONSTITUTION: An adaptive sound field control soundproof device comprises a resonance-type noise reducer(200), an active sound field control part, a solar energy current collector(400), and a soundproof wall(300). The active sound field control part is coupled with the resonance-type noise reducer. The solar energy current collector is attached to the soundproof wall in order to provide power for the soundproof device. The soundproof wall is made of a sound absorption panel or sound-absorbing material which can reduce the amplification of noise due to reflected sound. The active sound field control part is switched on/off according to the frequency band and amplitude of noise caused by a mobile noise source.
