Abstract
A blasting noise generated by blasting work, which is a kind of shock-noise, influences the human body. A civil appeal due to blasting noise causes work discontinuance and downsizing of a blasting scale. Most of soundproof facilities for reducing a blasting noise is installed at each working spot by itself and the degree of a noise reduction is very low. The aim of this study is to recommend a technology on noise reduction considering the method and material of soundproof facilities. As the first study step to acquire basic data, investigations on the installation time, installation method, and material of the soundproof facilities have been done at about 20 tunnel work spots such as railroad tunnel, road tunnel, tunnel for electric power.
