Abstract

In order to achieve the effect of low frequency noise reduction, usually the thickness of noise reduction facilities is relatively large, which increases the cost, how to make the economy and vibration and noise reduction in residential life balance, this paper proposes a thickness of 4mm two-dimensional phonon crystal thin plate, phonon crystal part of the material is organic glass, the rest of the structure material is transparent silicone rubber, in the premise of ensuring the light transmission, using Comsol for vibration band gap and transmission loss simulation, the results show that in the range of 500Hz to achieve a broadband vibration and noise reduction.
