Re: [LAU] DIY acoustic absorbers?

Gabriel,

Check out the DIY page at ATS acoustics. For $72 I bought:Roxul
Rockboard 80, Mineral Wool Board, 2 Inch (6PK)

I built my own frames and covered with fabric from Spoonflower that I had
custom printed with images of favorite musicians, so the 2x4 panels look
like art. They are spaced 2" from the wall.

The general rule of thumb is to stagger the panels and cover 50% of the
space with absorbers.

Sounds like you are almost there with the bookcase and carpet. I'd add a 6
pack of panels to the other walls and ceiling and go from there. Maybe
add a good subwoofer.

In my case I had a drum set against a live wall that I wanted to tame
before going deaf!

These did the trick. I have one drummer that plays really loud --- I'
thinking of adding a few panels on the ceiling.

Cheers!

Bob
