Definition
A microphone worn against the front of the neck, held in place by an elastic strap, that picks up speech directly from vibrations in the throat rather than from sound waves traveling through the air. Because it senses vibration at the larynx, it ignores most surrounding noise and is used in high-noise environments such as open-cockpit aircraft and military helicopters.
Plain English
A microphone worn on the neck that picks up your voice through the vibrations in your throat instead of from the air around you, so it works well in very noisy places.
Context Anchor
Seen in aircraft communication equipment, especially where engine, rotor, wind, or cockpit noise makes a normal mouth microphone harder to use.
Why Pilots Care
Enables reliable voice communication with air traffic control and crew members when engine noise or wind would otherwise make normal microphones unusable.
Intuition Check
A throat microphone is not just a small microphone placed near the throat. Its purpose is to sense the vibration of the voice in the neck rather than rely mainly on sound traveling through the air.
Example Sentence 1
The biplane pilot wore a throat microphone because the open cockpit was too noisy for a conventional boom mic.
Example Sentence 2
Wearing a helmet with an integrated throat microphone let the crew talk over the roar of the engines during low-level flight.
