Rod, Space, et al :

I'm researching absorption coefficients on OC 703 and 701.

According to Bob Gold's Chart, 703 2" (plain) mounted flush to wall has the following properties:

125 250 500 1k 2k 4k NRC
0.17 0.86 1.14 1.07 1.02 0.98 1.00

This past weekend, I began fabricating some acoustic treatment for my mixing environment.
The dimensions are as follows:

14' 6" L x 12' 3" W x 7' 11" H

Hi Rod, Space, et al...

A few weeks ago, I was hired to do a remote for a band - actually, to mic up drums and get tones and levels on location.

This band had made arrangements with a local nightclub to use their room during the day when the club was empty.

Bert Stoltenborg made an announcement that Eric Desart passed away yesterday.

Eric was a moderator for this forum for a period of time - and was a rather brilliant man in the field of acoustics.

He will be missed.

An old friend of mine wants me to re-do his recording studio. I design, he builds.

Basically, what he has now are 2 nice sized rooms and one small control room. Concrete and blocks.

First thing I've done is ask him for exact dimensions and construction materials, fixture locations, etc.

Hi everyone,

Hi!

I'm about to build my home in a hill neighbourhood, where there is an existing house to be knocked down. The land is 10 x 20 metres and i'm planning to build the house on the back part. The back part is the lowest part of the land, and i want to build basement to level it and build the house over it.

Good Evening All and Hi from the UK

HELP!

First of all may i say thanks for looking at this thread and any information shared will be greatly received.

Hello...
My editor and I just moved into new offices and it seems that we can hear more external sound than we did.
The outside hallway is wood and our doors have windows.
The offices are 9'x12'x8' (WxDxH) and there is no insulation above the drop-ceiling.

Hi all, Sunday i've finished the acoustic treatment in my home studio and everything seemed to play properly, but when I sat down at the listening position I noticed a phase cancellation on the low.
From the measurements there's a hole of -10db at 63 and 66Hz
I followed all the directions to the acoustic treatment, but this thing I do not know how to handle it.
