| The book is aimed at studying systematically the propagation of sound generated by fitting noise in light gauge walls and their basic combinations following EN ISO 38221 ?Laboratory tests on noise emission from applications and equipment used in water supply installation? using an installation noise standard (INS). An important result concerns the propagation of fitting-induced vibration energy through light gauge walls, which do not run face to face from the wall as expected but mainly over the top and bottom U-profile of the wall. The practical target consisted in finding solutions for material and mass combinations as well as optimal connection between walls creating rooms so that the sound propagation of noise generated by commercial non-classified fittings is reduced to less than 30 dB, the sound level value of whisper. Non-classified customary fittings, the most common group, produce a sound level of 36 dB at a flow of 25 l/min Using the results the noise level can be reduced to 30 dB and better independence created for the expenditure wanted and an improved wall design. http://bookshop.europa.eu/en/analysis-of-fitting-noise-propagation-in-lightweight-steel-constructions-and-design-solutions-for-their-prevention-afinopro--pbKINA26011/ | |
