Does plastic piping increase or reduce plumbing noise?
The type of piping used in plumbing systems is not the major factor controlling the noise generated in a building.There are differences between the various materials and in general, the heavier the pipe, the less sound is radiated. The noise radiated from pipes is usually negligible compared to that radiated from the partitions and the structure. It is much more important to ensure that all resilient supports for the plumbing system are properly installed and that quiet fixtures are used where possible. • What kinds of resilient materials are used below floating floors? A floating floor system is designed to have a fundamental resonance far enough below the frequencies of interest that vibration transmission is significantly reduced for frequencies higher than this resonance. The mass of the floating layer and the stiffness of the resilient supports determine this frequency. Materials used as resilient supports include rubber or neoprene pads, cork pads, some special composite material
