Intelligibility Test

Technique

A sound testing technique for checking whether spoken words, instructions, or important audio can be understood.

Description

An intelligibility test checks whether participants can clearly hear and understand speech or other critical audio. In immersive work, intelligibility can be affected by room noise, headset fit, spatial audio placement, music, accents, reverb, and competing sounds.

Typical Use

Used during acoustic testing, sound implementation, onboarding design, accessibility review, QA passes, and public installation checks.

Scope Note

This technique may include speech playback tests, volume checks, subtitle checks, room-noise review, headset tests, speaker tests, and participant comprehension notes.
