The noise damping in the gas pipes

Abstract

An effective noise damping system has been introduced at AB Lietuvos Elektrine Company. Natural he gas pipelines were insulated with noise-reducing materials to reduce the noise caused by regulators. ed Measurements at the pipelines indicated that the produced maximum noise level (2500 Hz) exceeds se the standard limit by 24.8 dB. After insulating the pipelines with nose-reducing materials the noise level at the regulators was reduced by 13 dBA and at the insulated pipelines - by 33.5 dBA.
