Question: How do Gas Turbine absorption silencers work?
Answer: An absorption silencer works according to the absorption principle. The sound waves
hit the insulating material inside and are thus absorbed. The sound energy is converted into
thermal energy, which is then dissipated into the environment. This effectively reduces the
sound level. However, in the gas turbine exhaust environment, the velocity and temperature have the major role in the selection of appropriate materials for sound absorption as well as survival.
