The Bandwidth of Human Perception and its Implications for Pro Audio

Locked away inside its shell, the brain has ever only learned about the world through our five primary senses. With them, we just receive  a fraction of the information actually available, while we perceive  far less still. A fraction of a fraction: The perceptual bandwidth. Conscious perception is furthermore subject to 400 ms of latency, and associated with a temporal grey-zone that can only be tapped into via reflexes or training. Based on a broad review of physiological, clinical and psychological research, the paper proposes three types of listening strategies we should distinguish between; not only in our daily lives, but also when conducting subjective tests: Easy listening, trained listening, and slow listening.
