Effect of airborne sound on installation noise. Part 2: Practical application
The noise excitation of buildings by service equipment takes place by both structure-borne and airborne sound. Mostly sound transmission is determined by the structure-borne portion. For some sources, however, the contribution of airborne sound can't be neglected. A typical example is the EMPA-hammer, defined in the Swiss Standard SIA 181 as a standardized source for the simulation of user noise. If airborne sound contributes substantially, conventional measures for noise reduction based on elastic isolation between source and building won't work properly. In order to develop efficient measures for that kind of excitation, structure-borne and airborne sound must be separated and investigated in context with each other. User noise from sanitary installations can produce high sound levels in adjoining rooms as well as in the installation room itself. Often airborne sound radiation of the sanitary object significantly contributes to installation noise. The airborne contribution depends on the structure borne sound insulation of the sanitary objects. For installations with effective structure-borne sound insulation the reduction of the airborne sound radiation with e.g. bitumen mats can be decisive to meet the noise protection requirements given by building law.
