The Electrical Generating Systems Association (EGSA) is the world’s largest organization exclusively dedicated to on-site power generation. It has rated silencers into 7 classes. Generally silencers are one of or a combination of three types of devices: 1.Reactive silencers, often referred to as "chamber" silencers, generally have their peak DIL in the 63 or 125 Hz OBCF 2.Absorptive silencers, often referred to as "packed" silencers, generally are most effective in the 250 Hz through 8 KHz OBCFs. 3.Resonators are generally specifically designed to have an effective DIL over a very narrow range, usually no more than a single octave. Reactive Silencers are thought of as Exhaust Silencers and their performance is usually based on a "typical" Exhaust Gas Temperature (EGT) value. Generally Absorptive Silencers are applied as intake silencers to best control the high frequency content of modern high speed turbocharged engines. When absorptive are applied in combination with a reactive silencer, as is becoming more common with higher speed multi-cylinder engines and requirements for noise reduction as an A-Weighted value are becoming more demanding, the performance of these must be adjusted for size and the longer wavelengths for specific frequencies in the exhaust system. Generally a Resonator is designed for a specific requirement.
