| Thanks again for your response Glenn. I realize the thicker the material (at least mineral wool, 703 and acoustic foam) the more I can capture lower frequencies. So like you said I'm hoping 2" and 4" foam in top of 2" mineral wool should be helpful and not detrimental. I'm just afraid of the foam capturing too many higher frequencies and not enough low ones.
So I'm going to use the superchunk method on the two 90 degree corners I have but the corner pictured has an odd hexagonal shape where I'm dealing with three walls, so how should I treat the top of this corner?
I'm thinking I could cover the whole top touching the ceiling and a 4th board on the ceiling (PICTURE A)? or should I put one diagonally touching the ceiling
and cover the center part of the wall? (PICTURE B)? |
