Key points of acoustic consultation for highway noise barrier design optimization

Abstract

Noise barrier treatment is a traffic noise pollution prevention project. Many domestic residents along high-grade highways are densely distributed and there are many sensitive points in the acoustic environment. Traffic noise will have a large environmental impact along the route. The design of the noise barrier from the EIA stage to the construction stage is inconsistent with the actual situation. Therefore, in order to improve and optimize the noise reduction measures along the line and reasonably control the cost of the noise barrier project, many should be optimized. We shoud clarify the noise barrier installation location, scale, acoustic material technical requirements, standards, and engineering cost estimates, focusing on the principle of no reduction in noise reduction, strong operability, and economical practicality, in order to highlight the purpose of reducing costs and increasing efficiency.
