Hi,

First off, this forum is great and has a lot of great information. I had a general question about running multiple diffusion panels in a sequence.

Lets use the Acoustic Fields QD-11 diffuser as the example panel:

If I build a sequence of 5 QD-11 panels along a wall, would you recommend keeping ratio identical (0/1/4/9/5/3/3/5/9/4/1/0) for all 5 panels, or do you believe that a barker code sequence would be more appropriate?

With a 5 panel build, you would end up with +1/+1/+1/-1/+1.

If you prescribe to the barker code methodology, do you have a preferred variation on the -1 panel to maintain the same design frequency and build depth?

Thanks!

C, Stay with the sequence provided in the drawings. You can increase the high-frequency response by making the well width smaller.
