Mic needed for oil rig - sparks from a mic?

FAQ #1553 Updated October 16, 2008


We require a microphone to be used on a oil-rig that has to be sealed so that it is not possible to generate a spark. Do you do such a mic and to what standard is it constructed?


If a mic is completed sealed, no air could hit the diaphragm and the mic would not operate.

Can a microphone generate a spark?
