Visual color affects perceived loudness of the same sound

Evidence

For example, the sound of a red car is perceived to be louder than a blue or green one, with a difference corresponding to 1–3 dB of SPL (Menzel et al., 2008). The audio track also influences eye movements and the direction of gaze, and sound has been shown to strengthen the salience of corresponding visual events (Coutrot et al., 2012). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1822

Categorization

• CANDY: A fun fact for conversation: the color red literally makes a sound seem louder by 1-3 dB.
• SEED: Potential essay: how multisensory integration means sound design for media must account for visual emotion cues, not just acoustics.
• corroborated: 2 independent passages support this claim — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1822
• XREF: connects to: Context-dependent compensation shapes sound perception much as with color vision; Visual and contextual cues bias human judgments of sound quality; Perceived loudness does not map one-to-one onto acoustic amplitude — David M.
