SilencerIt operates on a different principle from resistive silencers, which do not directly absorb sound energy. Instead, it utilizes abrupt interfaces on the pipe or auxiliary resonant cavities to cause certain frequencies of sound waves propagating along the pipe to reflect and interfere at the interfaces, thereby achieving the purpose of noise reduction. It is categorized into two types: the expansion chamber silencer and the resonant silencer.
Operation Principle of Wind Turbine Noise SuppressorFan noise suppressorAn equipment designed to eliminate noise generated by sound propagation, allowing gases and airflow to pass through while mitigating environmental noise pollution for humans and animals. It consists of multiple sections with different passageways, employing the principle of porous diffusion and metal sound-absorbing materials.
