Disclosed is an apparatus for decreasing blasting noise. The device for decreasing blasting noise for reducing the blasting noise generated during a blasting work includes a main body and a rubber board coupled to the circumference of the main body. The main body is installed vertically to the progressing direction of air for delivering the blasting noise to block the progress of the air, and the rubber board is flexibly adapted to the installation surface of the main body to fix the main body onto the installation surface. By using the apparatus for decreasing blasting noise, the blasting noise can be effectively reduced, and the scattering of scattering materials can be prevented. Moreover, the apparatus can be used multiple times, and is adapted for applications in site. |
