Sonata Exhaust and By-pass Silencers are designed for high working temperatures and to withstand expansion and dynamic loads. Staggered Silencer designs are commonly used in the exhausts requiring high insertion loss. Intake Dissipative Silencers are used to reduce the high frequency noise common on Inlets of Gas Turbines. High performance Acoustic Enclosures traditionally form part of the overall noise reduction program installed on Gas Turbines.
