Eberhard Zwicker

Eberhard Zwicker was a German physicist and a key figure in psychoacoustics, the study of how we perceive sound. He developed important theories and models to understand how the human ear and brain interpret complex sounds, including loudness, pitch, and timbre. His work helped establish methods for measuring sound perception, leading to better audio technologies like hearing aids and sound engineering practices. Zwicker is also known for the "Zwicker loudness model," which explains how we perceive loudness in relation to frequency and sound pressure, influencing both acoustics research and practical applications in audio design.
