Acoustic Foam Facts and Myths

Top Myths, Facts and Solutions in Acoustic Room Treatment

Use Egg Cartons?

No way! Anytime you talk about acoustical issues and how to solve them, this product pops up: egg cartons. It is a cheap option but doesn’t work for acoustics or soundproofing. The materials in egg cartons provide very little absorption to high frequencies but too thin to offer anything for sound isolation.

Can Carpets on the Walls Help?

Not much. Carpet seems like a very reasonable and workable approach to solving acoustical issues. You can hear the difference in a room with and without carpet. Soft carpet does provide high-frequency absorption, and if you use padding, it can provide some lower absorption too. But, in general, most carpet does not provide enough mass for sound isolation. Also, carpet does not absorb low levels requiring you to get bass traps to balance things out.

Furniture Can Absorb?

Some — depending on placement. Most people, when designing a space for a home recording studio, think they need to move all of their furniture out of the way. This isn’t true. If you have the room, you should strongly consider keeping your overstuffed comfy couch in the room and perhaps even your bookcase that is filled with books. Why? A well-placed sofa and other furniture, like the bookcase, can actually provide bass trapping and absorption of higher frequencies. And, although not huge, couches can help with lower frequencies too.

Foam to the Rescue?

Not all foam works. Foam is what most people in acoustics think of when it comes to acoustical solutions but not all foam is equal. Although much cheaper, household foam such as packing foam, mattresses, pillow foam, do not offer the same type of performance as acoustic foam.

What Should You Use To Solve Acoustical Issues?

Acoustic Foam. Acoustic foam is made for acoustics – being specifically formulated , manufactured with an open cell structure with the right ammount of porosity density hardness permiability and cell structure . It is an ideal substance to use for enhanced acoustics.

Depending on the tile shape and thickness you can tame your room a thinner tile may have an NRC of 0.5 (50%) good for general use in taming Highs and mids, if you need to tackle mids and lows aswell then you must go for a thicker tile which should have an average NRC of 70 to 100 (70%) to (100%).
