The only
name brand drum shields that I can remember using are the
CleanSonic shields and sound absorption panels. I've used others, both custom and name brand, but don't remember the names.
There's really not much to a drum shield, just clear acrylic (Plexiglass) panels ... at least 1/4 inch thickness, and some hinges. You can make your own!
See an earlier thread on this subject:
http://community.drummercafe.com/index.php?board=10;action=display;threadid=340As you probably already know, the Plexiglass will only reflect the sound, keeping it from spilling over into other instruments mics, etc. For true sound reduction, you need to have some absorption, as you mentioned. You can put foam on the panels, but don't forget the sides and behind the kit. If you're set-up is on stage and there is no sound absorption material behind your kit, such as a curtain, baffle, etc., you'll want to get something like this:
This would be the best way to control the volume of a very live sounding drumkit. By all means, if you don't need to deaden the sound that much, just use the panels ... and maybe some foam on the bottom sections.
It's going to take some experimentation on your part. I don't know what your kit sounds like or the venue in which you are planning to use the drum shields. The drumkit set-up, placement, staging, room acoustics, etc., all play a MAJOR role in the overall sound you are trying to control.
Hopefully this will help you a bit. If you need further information, I would need to get more specifics as to what you are wanting to do.
NOTE: The ClearSonic panel hinges (clear plastic) scare me a bit in that I don't know how sturdy they would be if you plan to move the shield around a lot.
