Instandsetzung von Schallquellen und Schall schützenden Teilen im Bau / Overhaul of Sound Sources and Noise Protecting Parts in Buildings
|Published in:||Restoration of Buildings and Monuments, December 1997, n. 6, v. 3|
In the context of sound propagation in buildings, we must differentiate between building parts which produce noise actively (water conducting parts, facilities with electrical motors and other equipment) and building parts which do not cause any noise but have a sound protecting function, such as e.g. ceilings or walls. We recognise that certain building parts do not change their sound protection function for long decades, while other parts are getting sound proof leaky due to amortisation (e.g. carpets, water spouts, window gaskets) or due to slow deformation in buildings (plaster dwellings, window and door surrounds). Moreover, various building parts are insufficiently dimensioned concerning their noise protection or have been carried out in a wrong way. This inevitably leads to an overhaul as mentioned above.
