Understanding the Visually Evoked Auditory Response

The video explores the phenomenon of hearing sounds in silent GIFs, known as visually evoked auditory response (VIA). It explains how our brains associate visuals with sounds, leading to perceived sounds even when none exist. The video discusses research on VIA, its potential link to synesthesia, and the curiosity it has sparked in online communities. Examples illustrate how visuals can affect auditory perception, highlighting the complexity of sensory integration in the human brain.
