A key element of a complete noise control packaged solution for power generation activities, via diesel or gas engine gensets, is the treatment of exhaust gases. Without effective exhaust gas treatment, the overall noise control design won’t be effective in reaching the client specification. Equally as important is the careful venting and potential after-treatment of these gases in order to move them away from the engine intake ventilation system and from human consumption. In order to protect employees from excessive plant noise and to comply with statutory regulations, installing exhaust silencers will support the delivery of an effective noise control solution, eliminate noise-induced hearing damage of personnel and prevent wider environmental noise issues.
Noise reduction can be attained using two principles of design specification – a reactive silencer affects noise reduction through reflecting and interfering with the transition of sound waves through the silencer. An absorptive silencer affects broadband noise by using an absorptive acoustic infill design and provides a low pressure drop.
