Plosives...

Plosives: sounds which are produced by obstructing the flow of air from the mouth or nose, causing a build up of air pressure. When released this pressure causes an explosive or popping noise.

Examples of plosives in English are /p/ and /b/ - place your hand in front of your mouth and say “Peter Piper picked a peck of pickled pepper” - you can feel and hear the /p/ make a popping sound.

Plosives are also known as stops.
