Noise Induced Hearing Loss

Can where you live cause hearing loss?

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.

Typical weight expected from different building materials

Building Materials Weights Guide

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.

Acoustical Glossary

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 Reliable?

“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 […]

How Does Constrained Layer Damping Work?

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 […]

Soundproofing Principle - Add Mass

Mass loaded vinyl isn’t the only key to good soundproofing

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. […]

Soundproofing Insulation

Should I use foam insulation or fiberglass insulation?

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 […]

Soundproof Drywall

Should I use soundproof drywall or build my own?

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 sound board to soundproof my room?

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 […]

Soundproofing a room with stairs

Watch out for the Stairs when Soundproofing

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 […]

Dealing with low-frequency sound (bass) in your soundproofing project

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 […]

Soundproofing Floors

Soundproofing tip: floor-to-wall transition

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.

Soundproofing Tip: Ceiling to Wall Seam Intersection

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 […]

Soundproofing Concerns for Suspended Ceilings

Soundproofing considerations for suspended dropped deilings

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 […]

Should I soundproof my foundation wall

Do I need to soundproof my foundation walls?

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 […]

In the Studio – Recording Magazine

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.
