Hi,

Lawrence It depends on whether you're looking for absorption or diffusion, and at what frequencies. Try http://www.realtraps.com for a starting point, then have a look at Ethan Winer's acoustics faq and his instructions for home brewed bass traps at http://www.realtraps.com. You should find some indications of where to start. If you have questions about room treatment, try http://www.musicplayer.com/cgi-bin/u...bb=forum&f=26& Have fun. -- Glenn Booth |

Hi, Can anyone give me some suggestions on DIY acoustic panels? Might be some web-site that can teach me how to make that? Thanks in advance. Lawrence Something that I have been advised to do and will do when the rest of the renovations are finnished (sigh) is to buy some ready made canvasses that artists use. They consist of a simple wooden square or rectangular frame with canvas stretched over the front. They are quite cheap to buy and come in all different sizes. I think the frame is about an inch thick. Then you purchase some fibreglass or polyester insulation material that you normaly find in ceilings and walls. There are two types that I know of, compressed fibreglass boards, can be found in different thicknesses, or the regular fluffy stuff sold in big bags. The compressed boards are easiest to work with and may absorb more sound. Simply find the right thickness board, or use the right amount of the fluffy type and fit it into the back of the canvass frame. when you have a nice snug fit you can staple a sheet of cardboard over it to seal it up. What you do with the canvass side is up to you and your creative mind. Then hang them up where you want just like a picture. Bunch them together if you like and create a large wall pannel. I will probably try this. PS: The compressed boards often come with some kind of foil sheeting stuck to the front of them. Try to peel this of as it will act as a reflective barrier. Also, I've read that using thick oil based paint to decorate the canvass may also act as a reflective barrier and prevent all of the sound from reaching the panel. You could try playing around with some water based dyes, these won't block the block the holes in the canvass, or just leave them plain. Dezza. |

Lawrence http://www.foambymail.com/ aka The Foam Factory sells several variants of acoustic foam ( in colors too!) along with columns and corner treatments. I haven't tried those but, did buy a mattress pad from them several months back. They sell on eBay as well for less than what they sell from their site for. Do an Ebay seller search for the ID foambymail or email them direct from their site. Nice guys to deal with. John |

The ones I received had a strong chemical odor when new that I found quite irritating. I put them into the garage to age for a month or two before then mounting them in the listening room. Those who are chemically sensitive, or just sensitive to odors, will want to consider this. I've also ordered panels made of rigid fiberglass (the other main material used for acoustic treatments), and when received, they did not have any odor. Also, according to the absorption curves I have seen, rigid fiberglass has considerably more absorptive power per unit than foam. Its lifetime is also greater; I found that foam started to deteriorate in 5 years or so and eventually had to be replaced. However, foam is cheaper to start with, and perhaps if it is fabric wrapped, the deterioration can be slowed. None of this is meant to say that foam can't be a good choice -- it's clearly an important material in many applications. However, there are several factors to consider before making a choice.

Lawrence I have european measures: on a mansonry wall(light plasterboards are not stable enough) you can make a frame of 19mm MDF in the size 100cmx70cm(outside) and fix it airproof . On top glue a 3mm hard fibre board with the white side out. Two thirds of the inside is filled with mineral wool. The height of the frame is calculated with the empirical formula: h(cm) = (390/fs)^2 :3 fs is the absorbed frequency, so for example for 65Hz the height will be 12cm. This absorber can be constructed for around 20 bucks each, best it is put into room corners, one on each wall. -- ciao Ban Bordighera, Italy |
