Matching audio to a visual scene requires scene-appropriate impulse responses.

Evidence

The auditory scene naturally connects to the visual one, something well known in Hollywood, where more often than not postproduction studio voiceovers replace on-scene audio; these are processed with realistic impulse response functions appropriate to the scene. Mismatches are immediately detectable as amateurish. — Eric J. Heller, Why You Hear What You Hear- An…, 2526

• QUESTION: How exactly are impulse-response mismatches perceptually detected, and can this trained ‘amateurish’ judgment be made explicit?
• XREF: Connects to the reader’s broader question of how sound becomes perception — scene conformance as a perceptual truth-telling cue.
