Square silencer Application
It is mainly used to reduce the intake and exhaust noise of the fan. It can also be used to reduce the noise of the exhaust pipe. The sound attenuation is 15-30dB and the pressure loss is less than 500Pa. When the noise source of the fan is at the maximum noise level, its frequency spectrum value is often more than one, and for different frequency spectrum bands, its noise reduction requirements are different. For this reason, the series of ventilation duct mufflers and induced draft fan mufflers are all of the impedance sound flow type, adopting a resistive structure that absorbs and muffles high and medium frequency noises and a resistive type that dampens mid and low frequency noises. Structure, at the same time, two sound-absorbing and silencing areas of high frequency and low frequency are adopted in the resistance channel to maximize the widening of the silencing frequency band to achieve a good silencing and noise reduction effect.
