[Organizers] Re: Help making an ugly hall pretty?

Note my comments below fall into the tangent of sound versus visuals. Re using fabric for visual and sound ... While chiffon fabric would certainly pretty a space up, it shouldn't alter the sound. We've been looking into this to help behind the band at the upcoming Chattaboogie weekend. To get more than a simple "this is what I believe" I tracked the following down on the Internet (so must be true!!!! :) ... Sound Absorbing Fabric Fabric that will absorb sound frequency waves is thick and porous. The waves enter into the fabric, and some become trapped in the fibers and folds and convert from sound energy into heat. Sound energy that makes it through the cloth hits the wall or window 6” to 12” beyond. It is reflected into the curtain again. Some more noise will be absorbed. The waves that pass back through the curtain into the room will be softened and dampened. Echo and reverberation are controlled, and listening enjoyment is improved. The best fabric is thick, 32-ounce velour type cloth. Heavy blackout curtains are good too, especially multi-layered curtains. Some fabrics have an NRC (noise reduction coefficient), the higher the value, and the better at decreasing reverberation, reflection, and echo. Acoustically Transparent Fabrics Transparent fabrics are used to cover acoustic panels, bass traps, and diffusers that are made of absorbent insulation. They cover and contain the fibers of the insulation while permitting soundwaves to pass through as if they weren’t there. Many fabrics are transparent. To check if a fabric is transparent, hold it up to your mouth and blow through it. If the air passes easily through it, it’s transparent. (...) Quilts have the thickness to help with sound, which Atlanta uses for their weekend dances. Cheap version of that are moving blankets. Official sound absorbing blankets cost more and I (informal thought) probably not worth the higher price versus doubling up cheap moving blankets (if necessary). BTW, St. Louis' Childgrove has plastic water pipes cut/set for hanging their quilts. The quilts are for both visual and sound improvement (and space defining). I'm impressed with how they are easily placed where needed for optimum control (configuration, sound, visuals) of the space. This isn't something you'd want to do for a simple evening dance. -Heitzso On 12/14/24 19:55, Kimbi Hagen via Organizers wrote:
