| Noise reduction box |
|
| Noise reduction box is made of porous plate and sound-absorbing material, when installed they are banded together with bolt piece and piece, installed in turbine inlet and the exhaust passage, forming noise reduction box with easy installation and clean appearance. When the airflow flows through the noise reduction box, the acoustic will cause vibration of air and fine fiber in absorbing material pores, which can convert the sound energy into heat energy to distribute, and thus playing a role in attenuating noise. The size and ventilation area of noise box should be determined according to the size and requirements of the unit. |
