Classroom Noise Problem

Ted,
Attached are pictures of the area I would like to put sound absorbing material in. It is so noisy in here because there is nothing to absorb the noise. I think it would be easiest to put the material on the ceiling, but I welcome your advice. It’s been a while since we spoke, sorry I took so long to get back to you. I did receive the samples and I’m impressed. Look forward to hearing from you.

Great, thank you for the pictures. I would like to add a picture of the center and a little write up about it on the soundproofing and acoustics blog that I write, would you be ok with that? I’m sure there are others out there looking to fix the same problem. It’s amazing that such little bodies can make SO much noise!!! 😀

Anyway, the pictures were a great help, thank you for taking the time to send them. Up until a few years ago, my mother had been the administrator for a few daycares for years and years. I had a pretty good idea in mind as to what you were dealing with in terms of room type, but the images were a good confirmation. Because of my familiarity with your types of business, I have a pretty good idea where you are coming from both visually and aesthetically.

As far as products go, the Echo Eliminator really stands out as a potentially VERY good option for a few main reasons. The Echo Eliminator is a panel made from recycled cotton, like a 1″ piece of felt. The standard size is a 2′ x 4′ panel and it is available in nine different colors. These panels are very light weight and class A fire rated which are both very important. If something were to happen and a panel were to fall off of the ceiling, because it is simply a sheet of cotton and weights only 2lbs, it could hit a toddler square in the head and not hurt him/her at all.

One thing I have always thought about and wanted to see is a unique and simple type of installation. The cotton is VERY easily cut with a large Fiskars fabric scissors, the ones with the orange handle. I’ve always thought it would be neat to see a center use the scissors to cut the panels into cloud shapes using the three blues and the white colored panels and glue them to the ceiling. If a smaller cloud shape were glued to a bigger one, it might give the form a bit of depth as well. Again, I don’t know of anyone who has ever done this so I’m not positive that it would even look good but I thought it might be a more inviting look than square or rectangular panels on the ceiling.

To come up with the number of panels that you might need, I would like to get the dimensions of the room from you. I’ve come up with a pretty easy way to at least begin the discussion about the quantity of panels in a room that people have found very successful. If you multiply the height, width and depth of the room to come up with the cubic volume and then multiply that by .03 (3%) the number that you are left with is generally the approximate square footage of panels you want in that room.

For instance, if your room is 20′ x 30′ and has a 9′ ceiling, the equation would look like this:

20 x 30 x 9 = 5,400
5.400 x .03 = 162
This room needs ~162 square feet of panels or approx twenty (2′ x 4′) panels.

The nice part about acoustics is that the absorptive surface can generally be placed anywhere in the room and have just about the same overall affect on the space. This is a nice luxury because it allows the end user to put the panels where they will be out of reach, look the best or be the most inconspicuous. Most people get the panels spaced evenly throughout the room to create a balanced look and feeling which will help slightly with the even acoustic once the panels are installed. One little trick that usually helps people is that by spacing the panels out, rather than installing them edge-to-edge, you can actually get a little more absorption per panel because the edges absorb sound as well and you end up with a surprising increase in overall absorptive surface area.
