Acoustics in college

[pandamonk]

Finally we're getting acoustic treatment in the colelge studios. I've been wanting them since i joined the course, and only now, that we have a lecturer who owns a commercial studio that recommended it, are we getting some. He's recommended sealed bass traps, which i'm happy about. But now he's wanting to install auralex metrofusers. These don't look too great for acoustic treatment. They are only 2", so wont they only affect frequencies above about 1,7kHz?

You are correct in your assessment - using only 2-inch foam is frankly a lame way to treat a listening room. Send your instructor to the RealTraps web site, linked under my name below, and tell him he is welcome to email me with any questions.

So 2" foam won't help below 1.7K?

Buying Auralex and paying a fortune makes some people feel better. But I don't think it's worth it. Unless you want to impress people by having expensive foam on your walls, I wouldn't use it.

I told him about realtraps and he said that he's heard of it.

I don't really feel right telling him to do that. He's the owner of the biggest studio in Scotland, and has a hell of a lot of experience with big names.

I did say that the auralex won't be that good, but i don't think he'd listen to me.

Not really. It might effect it slightly, but not anything major. The wavelength of a 1.7kHz sine wave is 8" long, so the first peak is 2" in. So that's the lowest frequency a 2" panel can completely absorb or defuse(i think ). Below that it will only effect part of the wave. That is why when you space a 2" absorber out 2" from the wall it will act like a 4" of the same density.

I don't want them to use it. He even said himself "It's just polestyrene with a studio acoustics sticker on it, and that allows them to bump up the price". I mentioned rigid fiberglass, and he said "yeah, that's what.......company uses, but they are very expensive".

Aaahh..thanks. I'm trying to come up with a scheme to treat a live venue's stage and dance floor to contain some of the stage volume and treat some nasty flutter echoes and reflections. Due to budget and strict fire codes I came up with a combo of theatrical drapes and 1" Auralex Sonofiber, which claims to have similar performance to 2" melamine. The flutters and reflections I need to treat are mostly between 400-2.5K, so it may be back to the drawing board for some of this.

Why not get some 2" rigid fiberglass and make some gobos. If they are spaced from the wall they will work down at lower frequencies too. you will need the 2" gobo to be spaced at least 6" from a reflective surface to absorb well down at 400Hz.

Ohh, had the lecturer today, and i said that the metrofusers wont affect below around 1.7kHz, which he knew. and that with sealed traps only really affecting below 500Hz, there will be a gap. He said he knew, but the rooms won't be perfect so as long as you improve it a bit.

Anyway, he said he's been checking out realtraps, and they have a diffuser newly out. I said that i talk to ethan, so... ethan, do you have distribution to the UK? We will probably order between 6 and 10 far version diffusers, a few mondo traps, or possibly 3 mondo room kits.

I shouldn't really say what we're getting 'cause I've not talked it over with them yet. But that's what I'll suggest we get.

I think we are looking for diffusers for the back wall, bass traps, and side reflection points.

Infact here are some plans of the room, and if you can recommend something, I'll print it off and take it in.

We sell direct all over the world. If we sold through dealers the cost would be far higher because they'd expect to even double or triple the prices, and you'd still have to pay for shipping. Typical shipping costs are listed on the Prices page of our site, and I'll be glad to get an exact quote when they're ready.

Again, if/when you get the go-ahead I'll be glad to help in as much depth as needed.

Ok, I'll talk to them soon. That lecturer is only in once a week.

You should just transfer here:

WOW,
Would if I could mate...

Actually. I'd say they have a hell of a lot better monitors, and acoustically designed rooms. And a larger selection of mics. But we have 2 studios with control 24s(i know their desks are a lot better), and 96 I/Os, with Protools TDM version 7 with quite a lot of plugins, and another with a large live room, 2 booths, 02R96, 192 I/O, Protools TDM version 7 with plugins.
