Visualizing sound: Scientists reveal hidden behaviors of sound waves

Phys · · 624 words · By George Wigmore

An international team of scientists has used computer simulations to visualize the behavior of longitudinal sound waves. Their research indicates that at extremely high intensities, sound waves exhibit non-linear behaviors and are perceived by the human brain differently than ordinary motion.
