Animated sound waves
Wave nature of sound – research at EMPA
Digital animation of sound waves between two acoustic mirrors, represented by two curved lines, showing the mirrors from above. The sound comes from the left. Intense red symbolizes high overpressure, intense blue strong underpressure.
Especially with high-frequency tones, it is possible to digitally investigate how sound (more precisely: sound pressure) propagates and how it is reflected by obstacles, here the acoustic mirrors.
