Zwa silencing bend (vertical bend)

Zwa silencing bend (vertical bend)

Purpose and characteristics:


There are three parts in the acoustic attenuation: the absorption and reflection of the near axial wave on the elbow wall, and the energy of the near axial wave changing into the energy of the inclined wave when turning, which is effectively absorbed by the sound absorption material. The inner wall of the anechoic chamber is filled with 50 mm or 100 mm thick centrifugal glass wool and covered with φ 6 - φ 8 porous steel plate.


Explain:


The noise attenuation decibel value of zwa50 is 7-16.5db (a). The noise attenuation decibel value of zwa100 is 10 ~ 22dB (a).
