What does audibility mean?
Audibility is the quality of being able to be heard — the measure of whether a sound reaches listeners clearly and at sufficient volume. The word derives from the Latin 'audibilis', meaning 'that which may be heard', from 'audire', 'to hear'. It appears most often in technical and professional settings: audio engineers assess the audibility of dialogue in a film mix, broadcasters monitor the audibility of transmissions, and hearing specialists discuss the audibility of speech across different frequencies. Poor acoustics, background noise, or low volume all reduce audibility, while amplification and good room design improve it. Though somewhat formal in register, audibility fills a useful niche that everyday phrases like 'easy to hear' do not quite capture: it names a measurable property of sound rather than a passing impression. Its antonym, inaudibility, describes sounds too faint to perceive at all. For anyone working with sound — from podcast producers to architects — audibility is a precise and practical term worth knowing.
nounThe quality or degree of being audible; the extent to which a sound can be heard.
- The quality or state of being capable of being heard.
- The degree to which a sound is loud enough or clear enough to be perceived by listeners.
"The engineer adjusted the microphone levels to ensure the speaker's audibility in the back rows of the hall."
"The lecturer wore a lapel microphone so that her words would carry with full audibility throughout the auditorium."
"Poor acoustics in the old theatre severely compromised the audibility of the actors' dialogue."
Without audibility, even the most brilliant speech is just air — it's the invisible bridge between a voice and an ear.

Etymology of audibility
Audibility comes from the Late Latin 'audibilis', meaning 'capable of being heard', formed from 'audire', 'to hear'. English borrowed 'audible' via Old French in the late Middle Ages, and the noun form 'audibility' emerged later, by the early 18th century, following the common pattern of adding '-ity' to adjectives ending in '-ble'. It shares its Latin root with a family of hearing-related words including 'audience', 'auditory', 'audio', and 'audit' — the latter originally meaning 'to listen' (as accounts were once checked aloud).

How audibility is actually used
"Audibility" is a relatively formal term, common in technical contexts such as audio engineering, broadcasting, telecommunications, and acoustics. In everyday speech, people more often say a sound was "too quiet" or "hard to hear" rather than referring to its audibility. It is typically used as an uncountable noun, though phrases like "the audibility of the recording" are natural in evaluative contexts.
