Imagine No More Footfall Impact Noise From Your Neigbors Living Above You


Beta Gel, a silicone based gel with almost unbelievable absorption qualities, as seen in this video from Japan Probe. If you could get this type of performance in a floor underlayment, it would greatly reduce footfall / impact noise. In fact Geltec does make an underlayment called NP Gel, but does not offer any information on it's IIC ratings. Hopefully, someone can import this to the States and do some testing.

In this video an egg is dropped from about 70 feet onto a pad of Beta Gel, the egg does not break. The host then throws the egg at the Beta Gel pad and it still does not break. Watch how the egg does not bounce. You can see how this product might make a great floor underlayment.

Press Release: QuietRock 525 and 527 Now UL-Rated

SUNNYVALE, Calif.--(BUSINESS WIRE)--Quiet Solution, the market and technology leader in soundproofing solutions, announced UL ratings for US and Canada today for two more of their soundproof drywall products, QuietRock 525 and QuietRock UltraSTEEL 527. Both products deliver superb noise reduction, are 5/8” thick, are 1 hour fire-rated, and Type X equivalent.

UL assemblies for QuietRock 525 are U386, L591 and W317 which include 16”OC and 24”OC single, staggered, and double wood stud configurations.

UL assemblies for QuietRock UltraSTEEL 527 are V464 and W460 which include 16”OC and 24”OC single, staggered, and double metal stud configurations.

Various QuietRock models are now part of 29 UL listings, including U301, U305, U309, U311, U320, U331, U334, U340, U341, U342, U440, U451, U453, U455, U465, U473, U493, U386, L591, W317, V464, W460, U376, U385 and V463.

Quiet Solution pioneered the soundproof drywall category in 2002, and leads the market with over 90% of installs. The company has 22 filed patents and makes over 25 Quiet®-brand products.

“Our customers wanted the added reassurance of UL testing on our verified fire-rated products; we listened and delivered,” said Steve Weiss, vice president, marketing. “Our investments in product development and reputable full-scale testing have resulted in a stream of QuietRock products that give architects, builders and contractors superb performance and ease of installation at the lowest total cost. Customers have voted with their project budgets, keeping us in the #1 spot year after year, with over 30 million square feet installed.”

A single sheet of QuietRock 525 delivers noise reduction equivalent to eight sheets of standard drywall, reducing noise by 75%. A party wall built with a single sheet of QuietRock 525 on one side of single wood studs delivers an STC rating of 51, meeting building code at lower total cost than other wall assemblies, such as double studs or walls built with resilient channels or sound clips.

The low total cost, simplicity and reliability of the QuietRock product line has made it the most popular choice for multifamily and commercial construction such as hotels, hospitals, and offices, as well as remodels and media rooms.

QuietRock UltraSTEEL 527 was developed in partnership with Dietrich Metal Framing, the leading manufacturer of steel studs. It was designed to meet the customer need for a superior soundproofing solution on metal studs that reduced labor, didn’t require multiple layers of products, and didn’t rely on failure-prone techniques. It is specially engineered to deliver superior noise reduction for interior walls built on UltraSTEEL, providing STC ratings of 55 or more at lower total cost and with simpler and thinner wall assemblies than other methods.

QuietRock-based assemblies may be eligible for LEED points, as LEED standards recognize the importance of improved acoustics.

Details of all QuietRock and QuietWood acoustic and fire assemblies are available at www.quietsolution.com/acousticfireassemblies.pdf.

Both products are available now throughout North America through traditional drywall distributors and independent dealers. Detailed product information is available for architects, engineers, contractors and builders at www.quietsolution.com.

Besides QuietRock there is another similar product called Supress. I do believe this company was started by a former QuietRock employee.

Soundproofing a fence

Soundproofing a fence, well that would be impossible because, you would have to make a really tall fence to block all the noise. There must be some way, because millions of dollars are spent to build those sound walls along our byways of transportation.

So a soundproof fence is out of the question, however you can build yourself a sound control fence. You can wrangle that noise to a tolerable level. The fence will have to be tall, at least 8 feet taller than the offending noise.

Updated: Soundproof Windows

A soundproof window is a second laminated window (two sheets of glass with clear plastic membrane sandwiched between) installed behind your existing window, with a dead airspace between. The second window should mimic your existing windows. So, if your seeking fresh air you will have to open two sets of windows to get to that fresh air. This type of setup is very effective at shutting the noise out and you can expect 80% or more reduction in noise.
When purchasing these types of windows, it is best to take a look at more than one manufacturer. You may prefer one design over another. Also, consider that there is only a slight difference in sound reduction with the different thicknesses of glass 1//4", 1/2", and 3/4". They will try to push the thicker sizes because they are more expensive. Some, may argue over this point, but it is really the dead air space between the windows that helps reduce the sound, and 3" inches is supposed to be the ideal distance between windows. The price for a 3' X 5' window will range from $500 to $1400.

If your on a budget you can just install another like window behind the existing one. That is if you have the space. The optimal air space gap between the windows should be 3 inches. Of course as always there is some disagreement over the what size the gap should be. Installation of these windows is very important, they should be airtight, no gaps.

Double pane windows are not as effective at reducing noise they may reduce the noise up to 20% and vinyl frames 30% to 50%.
