 Just so I understand, it looks like the Wildlife Acoustics microphone uses=
 the classic PZT arrangement of having the mic above, and closely spaced to=
 the boundary. In your design you come up through the boundary, and wrap th=

 I've got a related fabric question I hope someone can help me answer. The =
first several sets of EM-172 capsules I bought had black fabric discs stuck=
 to the front. The more recent ones are bare metal. I've seen electret caps=
ules come both ways. Does anyone know what those black fabric discs are cal=
led, and where I can get some? They seem to be a pretty standard item, but =
I can't seem to find them anywhere.=0D
