My DIY bass traps

Here's the relevant acoustic specs of Roxul: Code:

AHAAAAAAA !! GREAT !!! I am pretty much illiterate in the area of room acoustics. How to absorb/control frequencies below 100Hz ?

Looks good Rob. Very similar to the panels I made last year. I haven't done any scientific testing but the old 'close your eyes and listen to the space' test left me happy. I also have one whole wall filled with five bookcases filled with randomized paperbacks and books as a 'poor man's diffusor' that works well.

Thanks Rob. I didn't find the specific answer I was looking for, but it helped.

Rob, were those bales of 7, 4" bats, or were they 2" bats that you put together when you made your panels? In the pics it looks like you have two individual 2" bats put together.

Seven 2" batts per bale. I bought two bales. My supplier would not break a bale. Also lesson learned: bring a pickup truck. My Corolla pretty much didn't suffice

Heh heh, interesting Rob, I've never tried an electric knife. I just used a good sharp 8" hunting knife and don't recall any real problems. I think if I was going to make a corner trap like that I'd just set up a quick little jig that would get good straight precise cuts. Alot of interesting ideas here that I wish had been around 30 years ago.:)

Bazinga! Looks like granny might have some trouble cutting the turkey this Thanksgiving! Great stuff here all, and the studiotips link is fantastic. My plans to buy some acoustic treatment have been on hold until I was able to do some room freq analysis of both my room and prospective insulation. These two links in the studiotips forum helped clear that right up. Thanks!

You should look into UltraTouch cotton by Bonded Logic. Similar NRC to Rockwool but you can eat it. Also they make handy cushions for studio naps. Plus it's fire proof. The downside is no rigidity so you have to staple it to a frame for standups. Works fine wrapped in burlap and hung from hooks, sans frame. Also sheep's wool has the best known NRC but it's expensive in batts. Some people are investing in it for home insulation since it's more or less totally renewable (make more sheep), amazing at moisture and fire control, and you can eat the sheep. I prefer cotton over mutton though. -robo

Rob, How did you hang them in the corners? Or, did you just leave them sitting on the floor?
