highway soundproof solid wall barrier

 Highway Soundproof Panels build a solid wall barrier system between the road, home or facility along the highway. The sound absorbing panels do not completely block all the noise, they can reduce the overall noise level. As an effective noise proof barriers, the solid panel walls usually reduce the noise level by a 5-10 db (dB), the volume of traffic noise reduction. For example, to achieve 10 db lower, the barrier can reduce sound levels caused by a passing typical trailer.
