What You Need to Know About Acoustics (Part 3)

blog.rosebrand.com: We are looking at ways to use fabric primarily to provide sound absorption in rooms. Sound absorption reduces reverberation and loudness, and can also control reflections that may create strange sound images, echoes, or resonances. The quantity, concentration and distribution of sound absorptive materials in a room will vary depending on several factors; room size, the shape of the room, and the types of activities that will take place in the space.

I don’t really know anything about acoustics, but this article is interesting in that it takes the science of acoustics and applies it to fabric and materials that we probably all take advantage of. I don’t know how the use of velour masking changes the equipment needed of a sound system. It seems like this may be a chicken and egg situation. Should you choose your sound equipment based on the fabric you’re using and its sound absorption qualities? Or should you choose your fabric and its sound absorption qualities based on your sound equipment? I can see the value of this in permanent installations, but I’m not sure how much value this has on tours and the like. How much difference does it really make? How critical are these measurements and values? Not to downplay the importance of acoustics, but it seems like the amount of sound that soft goods absorb is minimal compared to the amount of sound output. But again, I don’t know anything about acoustics.
