[QUOTE="Greg Cameron, post: 2759, member: 42"] Hi guys. I posted this on the LAB too, but not much response over there that past day. I'm in a bit of a crunch, so I'm hitting up my comrades here: I have been told by several people "in the know" that one of the best ways to go these days with acoustic treatment is eco insulation since it's sound absorption properties are outstanding and it's non-toxic to work with unlike fiberglass. Frame it up and use Guilford FR cloth for covering and you're good to go. At the venue I work in, we've done complete surface measurements and figured that the ballpark for raw materials is around the $16k range just for the insulation and Guilford. There are of course other costs for wood & labor, etc. I was wondering if there might be a lower cost alternative out there that might be effective as well for acoustic treatment. Any thoughts? Thanks, Greg Response over there by Brad Webber: " "Acoustic treatment" doesn't really define what you're trying to do or what the material needs to do and just randomly throwing materials up as "acoustical treatment" may affect the room acoustics but not necessarily in the most effective or desirable manner. Are there any specific acoustical properties that you are looking to obtain? Are you looking at absorption only or also at diffusion? If for absorption, are you just looking for 'soft stuff' or are you looking for something that offers specific absorption at certain frequencies? Are you looking for a certain thickness or density?" My response: - We're looking to deaden the room as much as possible, period. The idea was to apply damping materials to almost all surfaces except for the floor.
