Room Treatment

[timt]

I am in the process of treating a 16x13x8 room with corner bass traps and some first reflection panels. The insulation I have found locally is Roxul Safe N Sound and is 3" thick. I'm going to double up and make the bass traps 6" thick and the wall treatments 3". From one of the sound treatment websites, I've gotten the total number of sq. feet of room treatment needed.

My question is this; can I count the sq. footage area of the bass traps twice since both the front and back will come into play as corner traps?

Thanks for your input.

I am curious how you know the amount of trapping you need. The proper method is to measure (acoustically) your emtpy room, add corner and first reflection traps and then measure it again, see what issues the room has and treat further to deal with outstanding issues.

Is this for a control room, tracking room or combined use?

Generally speaking you will want to avoid having untreated parallel surfaces in order to get a reflection free zone.

My combined room is just a fraction larger than yours and as well as building superchunks for all 4 vertical corners, my room needed 27 1200x600mm (4x2') broadband traps. I wonder how many you think you need for your room.

My room will be for both tracking and mixing. Atsacoustics.com has a program in which you provide room purpose, size, and surface type, and they respond with a very general estimate for square footage of treatment needed. I think the initial number that came up was 180 square feet of coverage. I'm certain there are more precise ways of determining optimal treatment, but for my purposes, this will be a good start. I am building 3 vertical corner bass traps (the fourth corner is a door and is more problematic) and the rest will be used as a cloud over the drum kit, and for first reflection points at my mix desk.
