    whats the difference in sound deadening and sound diffusion?

    i have read the comment somewhere on this site "you need to diffuse instead of deaden."
    i thought it was the same thing.

    Well actually you have absorbtion and diffusion. Absorbtion soaks up the sound waves and diffusion breaks them up into smaller pieces and re-directs them. To have a good room you need a balance of both. You don't want your room to be too live or too dead. You just want to treat the problem freqs. The approach is different depending on the room's purpose. Sometimes a room that's more "live" is better for tracking. In a control room you also want to kill reflections that can smear the stereo image and create comb filtering.

    To me "sound deadening" sounds (no pun intended) like isolation, which is something completely different. This would be keeping sound from being transmitted into or out of the room.

    No such thing as a stupid question. :c:

    thanks m bane
    thats what i ment "absorbtion" not "deadening". so, the aurolux foam absorbs sound and to defuse sound you have to build (or purchase) a defuser...is that right?

    Jimistone, you are correct. I am just learning this same lesson, it is a difficult one to get your hands (and mind) around. Check out another thread in this forum called "Studio Sound Treatment" that I started...tons of great info in there! Here is a link to the first page (there are 3 total so far...) :
