Plosives is the name given to the blasts and pops that are irritating especially when heard over the microphone. A pop shield functions by placing an obstruction in between the mouth and the microphone to eliminate plosives. It also helps protect a microphone from corrosion by absorbing moisture coming from a speaker's mouth.
