Members Primal Yell Posted August 24, 2008 Members Share Posted August 24, 2008 Thinking about putting these things in corners for sound aborbtion-- 1. A surfboard. (Plastic shell but LOTS of foam inside) 2. Foam body boards--for having lake or ocean fun--Ive got 4 of em.... 3. "Water Noodles", or "Water Weanie" floatation things, you use them in the pool or ocean. They are totally fluffy foam and soft. It sounds a little wacked, ,,,well, frankly, ,,I'm a little wacked, but they've got foam, and I can stack them to achieve increasing thickness, especially the foam "water weiners" and wave body boards. I think that I could mimick a corner bass trap with the water noodles--heck I can make them triangular and they have irregular edges--and it cost pennies in comparison to the commercial absorbtion products. I can stack the foam body boards and get to 8 inches of foam! The other thing is that these water toys look wierd and ecclectic and not as sterile. I don't mind looking wierd. My room has not been swept yet--I'm just assuming that I'll have some low frequency absorbtion issues which should be addressed. Give these water toys a try? Have a good one--and best regards in your studio. Greg Quote Link to comment Share on other sites More sharing options...
Members Ethan Winer Posted August 24, 2008 Members Share Posted August 24, 2008 Sorry, not one of those things you listed has any useful acoustic properties. Why not just get materials that are known to work well? Rigid fiberglass is not that expensive. More here: Acoustics FAQ --Ethan Quote Link to comment Share on other sites More sharing options...
Members Marko Posted August 25, 2008 Members Share Posted August 25, 2008 The surface covering the foam has to let the sound through, like cloth, or it Quote Link to comment Share on other sites More sharing options...
Members Tim Mayock Posted August 26, 2008 Members Share Posted August 26, 2008 While it takes some effort to get and to work with rigid fiberglass. It is the thing to use! I have done extensive research and used this stuff. Ethan's products are great. I have some of his absorbers. They are rigid fiberglass made into attractive, functional absorbers. DIY means less $, but you have to endure getting itchy for a day or so. You also need to have some basic carpentry/ assembly skills. It breaks my heart to spend money on something that isn Quote Link to comment Share on other sites More sharing options...
Members Majoria Posted August 26, 2008 Members Share Posted August 26, 2008 I've made a variety of panels including a vocal booth out of Owens Corning 703 rigid fiberglass, last purchase was $53 for 6 sheets of 2'x4'x2". Home improvement stores don't carry it, you have to go to a vendor which you can find here. The vocal booth made a HUGE improvement to vocal tracks just in my home hobby studio, think of what a room treated by a pro can sound like.

Members fuzzball Posted August 26, 2008 Members Share Posted August 26, 2008 The room in some cases is the most important part of the chain. With that in mind I am saving like crazy for when I move and have my new studio next year. Quote Link to comment Share on other sites More sharing options...
Members GodBlessTexas Posted August 30, 2008 Members Share Posted August 30, 2008 For low frequencies, you need bass traps. There are plenty of tutorials out there on how to make them from the DIY studio and A/V & Home Theater world. Do a google search on DIY bass traps.

Members Jimbroni Posted August 30, 2008 Members Share Posted August 30, 2008 As others have mentioned you're better off with fiberglass. Fiberglass is nasty crap to work with, but it truly is the biggest bang for the buck. The reason you can't use the watertoys, is because they purposely designed to NOT absorb anything. They are closed cell foam, this is so they don't absorb water and sink. They are meant to float. A sponge on the other hand is open cell foam, and designed to absorb water, which also means it will have some acoustic absorbtion ability. Most open cell foam is expensive when compared to fiberglass. Quote Link to comment Share on other sites More sharing options...
Members Primal Yell Posted September 1, 2008 Author Members Share Posted September 1, 2008 Are there any restrictions as far a the outer cloth fabric is concerned? Its all going to be porous---and work about the same ---right?? One fabric is about the same as the next--right ?? There is also a temptation to use the panel as being a type of "corkboard" or such, (since its fairly rigid) and put "post it notes" on it or pin up a piece of paper on it with a thumbtack----Is this one of those rules that you just never ever violate?? Avoid this at all cost or could you allow just a minimal amount of it? Quote Link to comment Share on other sites More sharing options...
Members Jimbroni Posted September 1, 2008 Members Share Posted September 1, 2008 Actually not all fabrics are created equal. This is why speakers are always covered with breathable fabric. Muslin and Burlap are two good cheap alternatives, then there are more expensive acoustic fabrics you can get. Corkboard is not a good idea. Then it depends on what you're doing with the treatment. For bass traps, the fabric isn't quite as important. If its for broadband treatment to control both low end and high end for say early reflections, then you absolutely need to be careful with your fabric choice. Either way I wouldn't spend money on fiberglass only to cover it with corkboard, that would totally defeat the purpose. Quote Link to comment Share on other sites More sharing options...
Members Music Calgary Posted September 1, 2008 Members Share Posted September 1, 2008 Sorry, not one of those things you listed has any useful acoustic properties. Ethan is awesome and smart and experienced -- but there's absolutely no denying that there are many fine studios on the scene treated with foam. And the treatment works fine. I've used the rooms. They are fine. And there *are* ill health effects which result from fiberglass exposure despite all the best claims of those who seek to profit from convincing otherwise.

(spare me the gov't links, I don't trust your gov't *at all*) Right. But the foam the OP was talking about, was closed cell non absorbtive. That will not get the job done. The reason many talk about fiberglass and rockwool is that it is cheaper than auralex foam and what not. Quote Link to comment Share on other sites More sharing options...
