Mind Your "P"s and "Q"s!
A pop filter is used with microphones to shield the diaphragm from sudden bursts of sound which can cause a popping effect. The shield is "transparent" to sound passage and does not interfere with the movement of sound towards the microphone. Pop filters are commonly seen in recording studios situated between 1" and 8" in front of a microphone.
