4.3 Sound reduction with RAUPIANO PLUSUNPROTECTED PIPEWORKBoth structure-borne and air-borne noises occur in drainage pipesystems. The wall of the pipe vibrates due to water currents and flownoises. The type and intensity of these pipe vibrations depend on a varietyof factors, such as the mass of the pipe, the pipe material, its inner sounddampening material and installation method.123The pipe vibrations are emitted directly from the pipe as air-borne noiseand are transferred as structure-borne noise via the pipe brackets to thewall.4When developing a sound-insulating drainage water system, both types ofnoise distribution must be taken into account.Airborne noise insulation with RAUPIANO PLUSFig. 4-4Sound distribution with sewer pipe systems.1 Structure-borne noise2 Standard drainage pipe3 Standard bracket (pipe clamp with/without rubber ply)4 Airborne noiseAirborne noise is reduced by RAUPIANO PLUS due to special materials,sound-dampening minerals and increased weight of the pipe system.Targeted mass optimisation in sound-sensitive areas of fitting elbows ofnominal diameter DN 110 to DN 160 provides further improvement atredirection points.Structure-borne noise insulation with RAUPIANO PLUSThe transmission of structure-borne noise to the wall is reduced withRAUPIANO PLUS with the use of patented, sound dampening brackets:- A supporting clamp with loose gap in the pipe is fastened to the wall- A fastening clamp rests onto the supporting clamp, keeping the pipe inpositionThis extensive physical decoupling of the pipe, bracket and wall meansthat the transmission of structure-borne noise is eliminated to a highdegree (see Chapter 7 for installation details).PROTECTED PIPEWORK5Fig. 4-5Sound insulation with RAUPIANO PLUS.1 Reduction of structure-borne noise2 RAUPIANO PLUS pipe with sound-dampening fillers3 RAUPIANO PLUS bracket, patented sound-dampeningsupport bracket4 Reduction of airborne noise5 Reduced overall noise level142325
