Need absorption for desk reflections

Hi all,

This seems an obvious problem but a search or two didn't show up anything.

I have an ITB mix setup and I've become increasingly aware of reflections off my desk (a big wooden flat surface) and would like to know if anyone has found a particular material to be good at clearing this up.

I guess I'd be possibly looking for a large, thin, fairly solid panel of some sort to attach to the top of the desk to eliminate these reflections. I've experimented with putting some regular acoustic foam in the way and the difference is astonishing but the foam is impractical and looks really untidy so if anyone had a good solution I would be very grateful.

Cheers, Dan

You could put regular panels make from OC or mineral wool, but it will be hard to write on top or what ever. I did see a picture of one guy on here who did it and it seemed to work pretty well for him.

Can you get rid of the desk? Or maybe replace the surface with a wire mesh?

Yeah thanks for the input guys. I still need the surface to function as a desk though. I was thinking, would a pin-board have any acoustical benefits?

Perhaps there's a gap in the market...

As a side note, Glenn, I got my GIK 244 panels the other day and they made such an enormous difference it is unbelievable. I've got one directly behind and between my monitors and one straddling a problem corner. The sound I hear is more focussed and even all around the room, not just where the panels are. So thanks very much.

Check out this other thread. As the photo shows, the idea is to capture the tweeter reflection at the speaker rather than at the reflection points on the console.



Console reflection solution?

Placement is most often the best first step. Avoid the desk reflections before treating them.

That's the kind of arrangement I have moved towards myself - speakers positioned more to the front, in front of everything. Thought that would solve all.

Funny thing today - tried moving the computer screen forwards and backwards - big impact around 300-400Hz based on how far I brought the computer screen forward. Go figure.....Hah!

(I would have little clue about any of this without measurement software. Best time/money spent. Sanity might take a hit, but good training in persistence)

There as always been a debate if the screen could effect the sound. Glad you proved it.

I'll play around some more once I refresh my FM2 license, but I could clearly A/B a 300-400 Hz-ish null based on my iMac's position, forward/backward. Forward was worse on right speaker, back better. Could be a bizarre desk/screen/sideofspeaker reflection interaction perhaps. As well, I have about a 4' listening triangle, so the toein angle probably directs a little more sound deskwise than with a wider triangle. And, my desk has two tiers (one of those guitar center mix stations), so I'll test out how height plays into it.....

I'm considering this very thing at the moment, with bits for the top of the speaker too.

How did you get on, 2 years later?
