Experimental Study on Sound Reduction Effect of Muffler at Water Piping System

摘要

In recent years, structure-bone sound generated by water piping system influences on the rooms in hotels and apartment houses etc, and a problem caused by the noise are increasing. So the experimental investigations on the sound and vibration reduction of structure-bone sound at water piping system by two size of expansion chamber type mufflers were carried out. The following conclusions were obtained.
