Diffraction sound damping member installed on top of soundproof wall

摘要

The present invention relates to a diffraction sound damping member installed in the upper portion of the soundproof wall installed to protect the inhabitants from the noise sources generated when passing traffic or trains, such as around the exclusive road or highway, railway, etc. In particular, artificial turf mats of synthetic resin are laminated on the outer circumferential surface layer of the circular pipe member in which a plurality of sound-absorbing holes are perforated on the front semicircular circumferential layer. It relates to a diffraction sound damping member which is installed on the soundproof wall of the feature that interferes with and attenuates the noise introduced into the interior through the sound absorbing port of the circular tube member.
