Sound Absorption for Voice Recording Room
June 4, 2012
I was shooting this for my own journal and didn’t think I would actually publish the video, as i’m pretty private about certain things I work on. Then again, I was pretty happy with the results and wanted to share what my treatment was.
Keep in mind that this is not for Sound Isolation. This is not a Sound Booth that will block out all ambient noise. This setup is merely just ‘treatment’ of a small space to make the vocals sound better (get rid of echo and deflection).
Sorry fellas, I have to warn you that the video (below) even gave me a bit of motion sickness. If you’re not interested in building out a room for voice recording, maybe you should just skip this one. At about 3:50 into the video, you’ll hear a before and after comparison (turn up your volume).
There are low budget options to sound absorption, but I wasn’t very happy with those results (I tried). When it comes to covering the most amount of square footage on the walls, the AudiMute stuff was my best bet.
I tried the heavy moving blankets to absorb sound, but going with the more expensive AudiMute Sound Absorption Sheets was worth the difference (and look much better). You can get a pack of (5) 4×8 sheets for $230 dollars.

I also tried a variety of cheap foam, but in the end, a box of Auralex foam wedgies solved all the deflection issues. I used about 12 on the ceiling and another 12 to make a Reflexion filter behind the Rode ProCaster microphone. A box of 24 Auralex Wedges will run you $99 bucks. You don’t need to cover every square inch with this stuff, just a few will treat a room very well.
For the floor we just added some thick padding. So for about $330 dollars, I feel we got some really good results in a fairly professional looking voice recording room. Hard to tell from the audio of the point and shoot camera I was shooting on, but through a high quality vocal microphone it’s a world of difference.
If you’re looking to buy Foam by the piece (not the box), you can find a variety of types on eBay starting around $5.00 dollars (Click Here).
