SOME VERY USEFUL ACOUSTIC REFRENCE DOCUMENTS ABOUT ISOLATION
Posted: Sun Feb 24, 2019 3:51 am
Andre has managed to track down some of the most useful reference documents from the Canadian National Research Council, about isolation walls, floors and ceilings, so I'm posting them here.
It used to be easy to find these on the NRC website, but a few years ago they "improved" their website, and actually made it almost impossible to find them. Basically, you have to know exactly what the document is called and where they hid it on their website, in order to download it. Fortunately, Andre has copies of the best ones, so here they are (Thanks Andre!):
IR-586 : "Sound Transmission Loss Measurements Through 190 mm and 140 mm blocks with Added Drywall and Through Cavity Block Walls" IR-761 : "Gypsum Board Walls: Transmission Loss Data" IR-811 : "Detailed Report for Consortium on Fire Resistance and Sound Insulation of Floors: Sound Transmission and Impact Insulation Data in 1/3 Octave Bands" "Sound Absorption of Gypsum Board Walls" IR-818 : "Sound Insulation of Building Façade Elements" IR-832 : "Sound Insulation of Load Bearing Shear Resistant Wood and Steel Stud Walls" NRCC-44692 : "A Simple model of the sound insulation of gypsum board on resilient supports" [/i][/b][/color]
