Description
【特許請求の範囲】
【請求項１】焦点を有する音波反射板と、該音波反射板の焦点に集束された音のエネルギーの消耗を促進する音波干渉器と、前記音波反射板の焦点に集束された音を前記音波干渉器内に導入する音波導入口とを具備し、前記音波導入口を狭い導入口とすることによって、前記音波干渉器内に導入された音が逆戻りして容易に外へ出られないようにしたことを特徴とする消音装置。
【請求項２】上記音波干渉器を構成する壁面の対向する面を平行とならない変則的な反射面とし、音波干渉器内には多孔質材料を配したことを特徴とする請求項１記載の消音装置。[Claims]
1. A sound wave reflecting plate having a focal point, a sound wave interfering device that promotes consumption of sound energy focused on the focal point of the sound wave reflecting plate, and a sound wave focused on the focal point of the sound wave reflecting plate. By providing a sound wave introduction port to be introduced into the interferometer and making the sound wave introduction port a narrow introduction port, the sound introduced into the sound wave interferer does not return and easily go out. A muffling device characterized by having done so.
Wherein the said sonic interferometer not parallel to opposing surfaces of the wall surface constituting the irregular reflection surface, is in the sonic interferometer according to claim 1, characterized in that arranged porous material Silent device.
