Aeropanel acoustic absorber

[ralphs99]

I've built myself some acoustic absorbers. They help to control the sound being reflected off the rear wall behind the listening position.
The overall dimesions are 1m high, 1.2m wide and 160mm deep. It's a broadband design and is effective down to about 150Hz becoming acoustically transparent below 100Hz.
It looks very striking and suits a modern decor. It also works very well! For anyone that has a similar problem where they are forced to have their listening position close to the rear wall, an absorber of this type is very effective.

There's a lot more information on a new web page devoted to it. Check it out! https://web.archive.org/web/20061110...20Absorber.htm

Looks good..... :T

I have a 1/2 wall behind the listening position that's treated and it makes a big difference.

Nice looking panel, Ralph. It looks like a good candidate for a CNC router. I hate to think about routing all those slots by hand.

Could u use something like this if the rear wall is farther away? My rear wall is about five or six feet away and its in dire need a some acoustic treatment.

Well, so is the rest of my room.

Scott for that distance you might consider a mix of diffusion and traps.

Thanks for the kind words. This is definitely a CNC job! The results look the part too. My wood-working skills are pretty average, and the CNC slots look superbly straight. Much better than I could produce even with a jig.

Scott, for your room, you probably need to be a bit more specific as to your acoustic problems. It's hard to say if an absorber like mine is the most appropriate device for your listening room.
