摘要
利用废旧汽车轮胎与水泥穿孔板两种主体材料研发出一种新型的复合吸声屏障,并从实验和理论上证实了该种声屏障在中、低频段吸声性能良好;同时制作成本低廉,便于维护,适合于高速公路交通噪声降噪需要。
A novel composite type of sound barrier is developed by using the recycled tires and perforated cement board, and it has been validated through experiments and theory that the sound absorption of this sound barrier is excellent in middle and low frequencies.Meanwhile this kind of sound barrier is low-priced and easy to repair,which is suitable for the noise control in the expressway.
