A pipeline wave absorber will be able to ingest the stress pulsation, avoid duct vibration and relieve sky audio effectively The fresh new magnitude regarding audio avoidance is comparable to the sound intake coefficient out-of voice intake framework, perimeter and you may urban area proportion out of a funnel cross section and duration off revolution absorber. For it trend absorber, and that spends a micro-perforated tubing given that a lining sound-taking in topic, its appears removing would be calculated using the Belov formula: The fresh new perforation speed regarding a micro-perforated tubing while the diameter and you can duration of mini-perforated tubing keeps a primary affect brand new consumption effect of a trend. The fresh frequency away from a standard hydraulic system is lower than 1000 Hz. […]
