The silencers and noise-control systems have been officially recommended by the Provincial Environmental Protection Bureau to all municipalities in the province.
In partnership with the Sichuan Environmental Acoustics Society and acoustic-environment specialists from the Southwest Architectural Design and Research Institute, the Sichuan Institute of Environmental Acoustic Engineering was established, offering strong technical expertise and complete testing and measurement capabilities.
The casings and sound-absorbing materials are carefully selected; the silencers combine superior acoustic attenuation with excellent aerodynamic performance and a long service life.
