QuietRock claims to improve STC rating by 15 – 20 points; the equivalent of 4 sheets of standard drywall. Downloads. It’s really crappy! I’m in bc and always use “aura” underpad. NWTL140828-03 STC 40 Assembly Components Finish material 1/ STC ratings are calculated by measuring sound transmission loss at 16 data points in a frequency range of 125 to 4,000 Hz – with Hertz being the frequency of a sound wave. Assembly Construction. Besides adding a soundproof membrane to a wall, another method to greatly improve STC rating is to move to 25 gauge studs at 24″ on center. If the wall's STC is high, and you are not planning on playing the drums until late at night, or are not living near the railway, you will need no, or very basic soundproofing system. I suspect if you check STC ratings assess the soundproofing ability of walls, floors, ceilings, doors, and windows. To get the exact STC-rating, some more calculations need to be done by the acoustical consultant. For floors, consider adding an additional layer of plywood or using concrete topping to increase mass and density. STC Acoustic Pads™ are 1/4-inch thick neoprene, 1-1/2-inches square. Using a common 5-ply CLT floor panel, STC ratings in the range of 50-59 have been achieved for this common assembly build-up. Here’s a website that tests various materials: https: The STC rating figure represents approximately the decibel reduction in noise that the assembly can provide. 5/8” Type X gypsum wallboard RC-1 Channels 25GA (24" O.

Applications: STC-rated materials are used in residential, commercial, and industrial buildings With IIC and STC ratings of 48 and 45, it’s ideal for floating engineered floors and for laminate flooring on plywood and concrete subfloors. It shows that the STC ratings for assemblies with plywood subfloors are consistently lower than the ratings for assemblies with OSB Meaning one company will do a test over plywood. Decoupling On their own, each of these principles of soundproofing is only moderately effective. 5″ light wt. Sources of Airborne Noise: Conversations, televisions, music, and outdoor noises like traffic and construction. For an interior wall that is made of 3 5/8″ metal studs with one layer of 5/8″ gypsum board on both sides, the STC rating is about 38–40. This is due to drywall’s larger mass and the fact that sound travels very quickly through wood. To reduce sound transmission, you’ll need See more • • • • •Sound transmission Coefficient (STC) rating During general full scale wall testing, cellulose effectively reduces the airborne sound from room to room. Of course, the rating is determined as an average based on the different frequencies between 125 Hz to 4000 Hz. Where a dwelling unit is adjacent to an elevator shaft or a refuse chute, the separating wall assembly must have an STC rating of at least 55 as required by Sentence 9. This added benefit of cellulose is Below are the STC ratings of various wall assemblies, each presented to help illustrate concepts, improvements and rules of thumb. Blown-in Insulation. Solid wood, on the other hand, has an STC rating of around 30-32, (depending on a range of factors, such as wood density). When planning your acoustics—especially in environments like conference rooms or medical facilities where sensitive information is discussed—knowing the STC ratings of different materials is crucial. 1 Rating methodology 2 Sound damping techniques 3 Legal and practical requirements 4 See also 5 External links 6 References The ASTM test methods have changed every few years. Soundproofing has several elements: mass (weight, density) airtight; Sound control is measured in STC ratings (sound transmission coefficient). I think I may go with 5/8" plywood, then 5/8" sheetrock. And it is SOUND TRANSMISSION CLASS (STC) – An integer rating of how well a building partition such as an interior wall, floor/ceiling, door, window, or exterior wall attenuates airborne sounds ranging between 125 and 4,000 Hz. The STC rating figure very roughly reflects the decibel reduction in noise that a partition can provide. This value represents your STC rating. Department of Housing and Urban Development offers resources and information on housing programs, policies, and assistance for individuals and communities. If the STC rating is 35, that means the material in question can reduce sound transfer by 35 decibels.
