Plain English Meaning

Ear-worn speakers that let the pilot hear radios and other cockpit audio clearly, while blocking out engine and wind noise.

Full Definition

A pair of small speakers worn over or in the ears that deliver audio from the aircraft's communication and navigation systems directly to the pilot, while also reducing exposure to outside cockpit noise.

Context Anchor

Used in flight training, aircraft cockpits, simulators, and any situation where a pilot needs to hear instruction or radio audio clearly.

Derivation

Headphones combines “head” with “phone.” “Phone” comes from a Greek word meaning “sound” or “voice.” The word points to equipment worn on the head for hearing sound or voice clearly.

Why Pilots Care

They allow in noisy cockpits and protect hearing from prolonged aircraft noise exposure.
