STC OF MASS LOADED VIn
STC
Sound Transmission Class (or STC) is a test rating of how well a building partition reduces sound. STC is the most common sound reduction measurement which is widely used to rate interior and exterior walls, ceilings, floors, doors, and windows. The STC rating figure roughly reflects the decibel reduction in noise that a barrier can provide. In short, STC gives you an idea of how much sound a structure might stop.
HOW TO CACULATE STC
STC is calculated by taking the Transmission Loss (TL) values tested at 16 standard frequencies over the range of 125 Hz to 4000 Hz which are then plotted on a graph. The curve created by data points on this graph are then compared to standard STC reference curves. The rating of the curve from the standard STC reference that matches most closely to the curve from testing is how the STC rating is determined.
HOW MASS LOADED VINYL WORKED
How the Mass Loaded Vinyl Wroked Absorb Sound
Mass Loaded Vinyl act a Acoustical Reflective barrier expecially it absorbed and insulated
noise from leaving the confines of a space. Acoustical waved touch a surface lead to generate energy casused the vibration during the transmission the vibration was enlarged and transfer to the surrounding enviroment. Noise Travel easily when the surface without acoustical materials layer they are easy to vibrate while if the construction structure were flexiable ,it would absorb the noise energy vibration and just allow little noise transmitted this is why you need a mass loaded vinyl since all the concrete wall or floor materials are not made of malleable ,The MLV act a spundproof barriers between the construction structure to avoid and prevent the noise vibration from the left place. The quality Mass Loaded Vinyl are with a flexibility it stop sound vibrations and prevent the sound trans in the air
How to install mass loaded vinyl
Installing MLV with wall
Mass loaded Vinyl placed against with the studs after this place all over drywalls to make the things perfect we usual recommend mass loaded vinyl hung in the horizontal position so that can control the number of steams which allow taping all sections morever the MLV can be placed over existing drywall
Installing Floors and celling with MLV
Measusre the surface and distacne bewteen selling and floor and leave a 1/2" spacing
Rolling out the mass loaded vinyl and mark the signal cut with a knife as per measured size
Install tubes and equipment with MLV
Cutted exactly dimension of MLV by a knife then use a taping
