ADVANCED INTERFERENCE SYSTEM FOR REDUCING A NOISE

摘要

A high performance interference apparatus for reducing noise is provided that the height of the soundproof wall can be reduced since the interactive region is formed at the location which is more highly than the soundproof wall. A high performance interference apparatus(1) for reducing noise comprises a body in which the side wall of the other side rearward and bottom wall of the bottom side are formed into one body. The body includes a first interference unit(13) in which the middle low frequency is interfered, a second interference unit(15) in which the low frequency is interfered, and a third interference unit(17) in which the high frequency is interfered.
