Untreated and treat room dimensions

Untreated and treated room dimensions

If I wanted to build a live room with a finished dimension of 20Hx28Wx38L (Louden 1:1.4:1.9), would this mean that I should build a room that is 20Hx30Wx40L and then finish it with 12″ interior walls with diaphragmatic absorbers built into each of the spaces between the studs?

Also, is 20x28x38 too big for a live room for recording a band? I realize that the usage of the room somewhat dictates it’s size. Too small is bad but is there such a thing as too big? Thanks.

S, Yes build 12″ larger in all dimensions. This is a great live room. Don’t change a thing.

Dennis. In one of the videos you mention that low frequencies will need to be dealt with when dimensions are less that 30′. Does this mean that with dimensions larger than 30′ LF treatment is not necessary or less necessary? Thanks.

S, No, low-frequency issues diminish after 30′ but are still there and need to be managed. You can’t get away from low-frequency issues. I am doing a project that is 40″ x 20″ x 60′ and we are treating issues below 50 Hz.
