Does common drywall texturing help acoustics by diffusing?

I'm debating whether to texture my new walls (with a 'grain' in the range used in residential applications). I may do have texturing done anyway for visual effect, but if there is any diffusion benefit (for higher frequencies?), I would have no hesitation. The room is about 18' x 20' x 7' 6" high. I'll have some broadband absorbers hanging in various locations. Thanks. Bob

No it don't. It needs more depth and pref an algorithm.

Thanks, that's kind of what I was thinking, but it is nice to know. Bob
