Soundproofing a New Studio


Soundproofing is very important when it comes to providing quality audio to your podcast or internet radio station. If we are broadcasting from a studio at home, some soundproofing will improve your sound and limit outside noises. If you are designing a new studio, there are some things that you should take into consideration during the design process.

Soundonsound.com has provided a detailed explanation of soundproofing and hopefully can provide you with some good tips if you are designing a sound proof studio.

Soundproofing

People often don't understand the difference between soundproofing and acoustic treatment, so, here it is in short: acoustic treatment makes your room sound better, whereas soundproofing is designed to reduce sound leakage in and out of a space — and there's little or no overlap between the two.

When trying to reduce sound leakage, identify the weakest points first, such as doors and windows, because if they're not airtight, sound will leak through or around them easily. More mass equals more isolation, but you have to double mass to get a 3dB reduction in sound leakage — so a more common ploy is to use two boundaries with an air space between. Windows, for example, can be double‑glazed, doors can be doubled up, so that you have one on the outside of the wall and one on the inside, and walls can have an extra plasterboard 'skin' added, again with an air space between them. The wider the air gap, the better the low‑frequency isolation.

Floors and ceilings are more problematic, and while we've built simple floating floors using board resting on high‑density mineral wool, we've never yet tackled a ceiling. Often, it really is better to find a way of working that makes less noise in the first place — such as using headphones late at night, or either DI'ing guitars or miking low‑wattage amplifiers.

Finally, I'm sure that many of the issues covered here will be the same ones you've faced in your own studios, but there are always new problems to tackle — so do keep those Studio SOS requests coming in, especially if you think you have a problem that may be a little out of the ordinary!
