I'm glad to provide you with sources for reading material for the weekend.

Ah yes, I remember reading that now. This is the reason small rooms need absorbtion to create an RFZ, right?
|
That is one of the reasons absorption is used in small rooms. The other is that small room acoustics sound lousy.

How do I know when enough energy from the reflection has been absorbed to "turn it down" 10db? Maybe that's the stuff I learn with a Master's.
|
An absorption co-efficient of 0.9 or greater.

Or maybe you could sketch a pic explaining the grazing answer?
|
Grazing is a small angle of incidence, typically meaning less than 5 degrees.. The attached drawing is of a 12' x 17' control room with a 2'x 6' RFZ centered 38% of the length and speakers in a 60 degree location. The shallowest angle of incidence for the first reflection point is 35 degrees.

In the meantime I will try to work on another sketchup of a potential CR with my new knowledge.

I am looking forward to it. Take your time. The more know, the better your studio will be. And you know, good studio building is 90% design and 10% construction.
