Splitter Absorbing Silencers
In cases where noise emitted from air inlet or exhaust openings must be reduced effectively Splitter Absorbing Silencers are used.
Such silencers (attenuators) consists out of a rectangular or cylindrical casing with sound reducing internals (splitters or baffles). The noisy fluid (air, gas or steam) is streaming through the gaps of the splitters, while the noise waves are penetrating the absorber material of the splitters. The sound waves will be absorbed (reduced) è attenuation, damping. The difference between the loud inlet and attenuated outlet is called insertion loss. The set up and the dimensions of the silencer splitters depends on streaming situation of the fluid and acoustic requirements. |
