Home theater/Studio
« on: January 13, 2006, 09:23:35 PM »
Hello,

I have room in a daylight basement that is 20L X 13W X 9H which will be used as home theater/practice room (drums).  The only wall that is partially below grade (concrete) is the front wall where I plan to put the stage and screen.

I have done some internet research and came up with the plan below for each section.

I am considering the least expensive but effective method.

Ceiling
1.Mass loaded Vinyl (MLV) or Green Glue (Audio Alloy)
2.Sheetrock  (1 or 2 layers) (size ???)

Walls
1.Soundboard (1/2)
2.Drywall (5/8)

Floor (no skeleton)
1.Acoustic Floor Mat (Corning – Quiet Zone) or Mineral fiber (2”)
2.One or Two layers of plywood (3/8 or 5/8)

Risers
1.Roofing felt (30lb)
2.Insulation (R19)
3.Plywood

Stage
1.Roofing felt
2.Sand ???
3.Plywood (2 layers)

Questions:

1.Has anyone used green glue and do you recommend over mass loaded vinyl.? (cost difference around 600.00)

2.Does the use of different products affect the overall quality of the room?

Your suggestions and ideas are welcomed.
Thanks in advance. Eddie C

You should take a serious look at Green Glue. Download this study by Pratt Engineering Students at Duke: http://deltadesign.pratt.duke.edu/Acoustics/  download the word document "Sound of Silence Final.doc" there conclusion was that viscoelastic damping was a little better than mass loaded vinyl. In this study they use QuietRock which has a viscoelastic layer built into the panel. Visit my blog for more information about Green Glue.

Don't forget to treat the walls so the room sounds good.

See the "Control Room Layout?" topic for more on this; an excerpt below:

The first reflections are a major concern as is bass resonance; bass traps are the typical solution for bass resonance. The location of treatment for the first reflections are very critical. If the room is all sheetrock the room will not have a flat response; it will be mid-bass heavy, so tuned panels maybe what you need.
