See through Drum Partition

[flano]

Does anyone know why at some live concerts perhaps with two drum sets on stage that one is sometimes surrounded by a clear wall of plexiglass or something. thanks

It's because the drum mics which pick up the sound from the drum they are intended to amplify, will also pick up any drums in close proximity, which makes sound mixing a complete nightmare. Sound can also 'bleed' into ambient microphones, placed to pick up resoncences from the whole kit, which again will pick up rogue vibrations from the other kit, so simply physically separating each kit makes it easier to maintain clear sound from each.

as well as the above answer it is to protect the singers mic from picking up thebsound of the kit. If a person doesn't have a strong voice then the mic's gain has to be higher than normal thus picking up more onstage sound therefore destroying the overall mix.
