Acoustic room treatment is a mix of science and art. This field is a welcoming arena for those into Do It Yourself projects. However, many don’t realize that many of these attempted techniques, whether in building a vocal booth or a home recording studio, just don’t work. Here are some common myths, facts and solutions in acoustics.
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 shaped for acoustics — being open cell. It is an option to use for acoustics. However, foam — whether acoustic or not — will break down within time, and can not be washed. Acoustic foam is also an investment since it can be costly.
- Acoustic Sound Blankets. Generally a new and highly successful approach to solving acoustical issues and also soundproofing problems are sound blankets. Evolved from the standard moving blankets, these sound blankets solve many issues. By adding substantial sound absorptive filler and sound transparent outer fabric, sound blankets have slowly replaced the need to have acoustic foam in some cases.
VocalBoothToGo’s Producer’s Choice line of sound blankets absorbs 80% of noise (NRC 0.8) and exceeds any competitor’s products in sound absorption quality and value.
Also, Producer’s Choice blankets come in different sizes and also with grommets. These blankets are affordable, washable, transportable and solves acoustical problems — no myth, just plain fact.
