How Much Do I Need?
Hi. Wonderful web site! I was hoping you could answer a basic question: I have a “grand room” shaped like a trapezoid. The shorter wall (about 16ft.) is the exterior wall. The tall wall (about 25ft.) reaches the peak of the roof. The ceiling is wood. The floor is ceramic tile. The walls are drywall and there are lots of windows. The sounds echo terribly. I can make acoustic tiles, but I don’t know if I should hang them on the tall wall, short wall, or if I need them on both walls. Also, I don’t know how many I need. Can you give me some general instructions?
Over the years, I have put together a simple equation that I have had plenty of success with. This equation is used to “take the edge off” of a room and make it much more usable. When dealing with listening rooms or recording rooms, it gets much more complicated. In this case, though, I am very comfortable stating that it WILL make a significant difference in the sound quality of the room.
To determine the SQUARE FEET of product or surface area to cover
Cubic Volume of the room x 3% = square footage of product
Height x Width x Depth x 0.03 = Sq/Ft
You don’t have to be spot on, so average the ceiling height and go from there.
Where To Put The Panels
From an acoustical standpoint, that doesn’t make much of a difference as long as they are spaced out fairly evenly throughout the room. If you had two rooms and put the identical amount of the same material in both of them, one room putting it on the ceiling and the other on the walls, you or I could go into those rooms with our eyes closed and would most likely not be able to tell the difference. The location of the panels is not nearly as critical as the overall square footage of panels/product introduced. So you have a lot of freedom here to work with the desired aesthetic or the functionality of the room.
Do you have anything you would add to help figure out the amount of materials to use in a room?
