According to a joint study between Charite University and a hearing technology company, the place you call home could play a vital role in whether or not you have hearing loss.
This brief from Fast Company says “Noise Pollution Is Secretly Killing You”, according to a study from the the World Health Organization and the European Commission’s Joint Research Centre.
Katherine Ripley summarizes possible health impacts of noise pollution for The Best of NJ, and suggests some solutions, including, of course, soundproofing your home: 5 Health Effects of Noise Pollution and How to Remedy Them
A study cited in this news article by the L.A. Times suggests that living with road noise can shorten your life. One of the ways the L.A. Times article suggests to minimize the effects of road noise on your health is to muffle the noise: “Muffle the sound at home. Consider whether freeway noise might […]
Living close to a major roadway could increase your likelihood of developing dementia according to a new study cited by CNN in this article. Researchers found that people living within 50 meters (164 feet) of a noisy road had a 7% greater risk of developing dementia. The level of risk decreases proportionally, they say, with […]
An analysis of 65,000 women living in Denmark found that living near noisy roads could make it harder to get pregnant, accourding to this news article from The New Scientist. The research team found that for every 10 decibels of extra traffic noise around a woman’s home, there was a 5 to 8 per cent […]
Below is a guide to the building materials weights for typical supplies used during the construction of your walls, ceilings and floors. Soundproofing Company recommends 5/8″ gypsum drywall for its heavy weight, at 2.5 lbs per square foot.
Don’t let a few soundproofing terms slow you down. This Glossary of Acoustic Terms will help you. Included in the glossary are definitions for various soundproofing words, as well as detailed descriptions of sound isolation concepts.
“Are acoustical lab tests really objective? If a company is paying for the test, don’t they just get the test results they want?” While some very competent material testing can be informally conducted by a manufacturer’s own lab, no one outside of that company will give any credibility to such data. In general, objective data […]
Breakdown of Constrained Layer Damping: Damping is the conversion of energy over time and distance. We are relying on the panel flexing when hit with a sound wave. This includes wall panel movement as a wave (bending wave) that is traveling laterally in the wall through the drywall (whatever). This flexing of the two panels […]
When researching soundproofing solutions, it’s common to hear terms like mass law, mass loaded vinyl (MLV), and massive drywall. From these terms, it’s easy to conclude that mass is the only thing that matters to soundproof a room. This is only partly true. Essentially, mass is not the only factor to consider with soundproof construction. […]
Foams are superior from a thermal perspective, but not for sound isolation. This might surprise some, but when using insulation IN a wall or ceiling, it doesn’t get any better than standard thermal insulation in a low / medium density, especially to control low frequencies. This could be fiberglass or medium density mineral fiber. The […]
Whether to use packaged soundproof drywall, also known as pre-damped drywall, is a great question. With “soundproof” drywall available at big box stores and drywall distributors, anyone would be nuts to not at least consider these products. In fact, this topic was brought up here: AVS Forum Discussion First, let’s consider that any pre-damped drywall […]
Should I use one of several sound board products to help with soundproofing? It’s a common question. Sound board products are marketed under many different names. In general they are made from waste material from the lumber industry. That’s a good thing. They are lightweight and a bit spongy, and that also seems like a […]
How to Ventilate a Sealed Room Soffit Mufflers and Dead Vents These ducts fit nicely in a room’s soffit. Yet there are times when a soffit muffler isn’t practical. In these cases, a Dead Vent might be more appropriate: The Dead Vent can be installed outside of the sound room, perhaps in a closet or […]
If you’re building a soundproof room, it’s often in the basement. In that instance, more times than not the stairwell becomes an issue. Many people want to use the stairwell wall as the back wall of their new room. Others want to use the space under the stairs for an equipment rack (that’s what I […]
We all want great sound in our home theaters, gaming rooms, rehearsal spaces or other rooms where there’s bound to be a lot of bass, which is low-frequency sound. Not surprisingly, specialty rooms generating a great deal of bass create special challenges in room design. Generally, the most difficult aspect of high-level isolation is controlling […]
A concrete slab is generally an asset for airborne sound isolation. The large mass (weight) provides for a great deal of sound isolation from vibrations entering or leaving the room. The slab does have an airborne sound weakness at its Coincidence Point (frequency). A floated plywood floor is often used to guard the slab against […]
How to properly transition from a floor to a wall while maintaining soundproofing performance. The use of Soundproofing Floor Underlayment, Acoustical Sealant, Acoustical Backrod, Green Glue Soundproofing Compound and Sound Isolation Clips are required in this assembly diagram. Don’t forget Putty Pads for the outlets. All penetrations need to be sealed for maximum results.
Above is a ceiling to wall assembly illustrating how a ceiling and the wall drywall layers should intersect to provide a good seal. Note that we want solid drywall to drywall contact. Don’t try and leave a gap. The illustration shows a gap that is 1/32 of an inch. Most drywall installers do not hang […]
The best answer is to save your money and not treat the walls. You could have the most impressive soundproof walls in the world, but you will not see their value with a standard dropped ceiling. A dropped (suspended) ceiling does very little to soundproof. The tiles are lightweight and not nearly massive enough to […]
If you’re building a room in a basement, you’ll have some walls that are built next to the foundation walls. And you might be wondering what you need to do in terms of soundproofing. Basically, we’re not worried about sound leaking through the foundation into the surrounding soil. We’re worried about sound traveling straight up […]
Recording Magazine – October 2010 Issue: In general, the most difficult and costly frequencies to address have always been those in the area of 125 Hz and below, which coincidentally happens to be, in our musical world, the power behind most of our music and special effects. Cut off everything below 125 Hz in your mix and see what you have left.
I wouldn’t and don’t spec resilient channel. The fact is there is no single standard for its construction. Some is 20 gauge, some 25, some in between. Some are slotted for flex, some are solid, some have holes. The design of the channel is not standardized. Not something we can count on. Also, it is […]
