Abstract

본 발명은 입사한 음파의 위상을 크게 변위시켜, 음파의 상호간섭에 의한 감음효과를 높이는 것을 목적으로 하는 것이다.An object of the present invention is to greatly shift the phase of an incident sound wave and to enhance the attenuation effect by mutual interference of sound waves.

다공질재료로 되는 다공질부재(15)를 복수의 차음판(12),(13)을 조합하여 구성된 차음판 집합체(14)의 외주부에 부착하고, 다공질부재(15)의 배부에 용적이 다른 독립한 복수의 공간부(16)을 형성하도록 하였다.The porous member 15 made of a porous material is attached to the outer circumference of the sound insulating plate assembly 14 formed by combining the plurality of sound insulating plates 12 and 13, and the volume of the porous member 15 is independent. A plurality of spaces 16 were formed.
