Visualizing Physics With Sound (Sonification)

• Web Geiger counter "plays" simulation data, sounds real
• Now: sound "visualizes" physics
• Physics and math of oscillations come alive when heard
• Assists learning process: adds other senses
• Makes science more accessible to print disabled
• Accessible also improves learning for sighted
• Under figures, gif-formatted equations: text in ALT tag
• Auditory Graphs
• Some Physics Graphs
• HearData: a sound player for data (Bert's Java)

Visualizing Physics With Sound (Sonification), Direct Mapping

Data converted directly to a format for soundplayer

1 cycle theta vs t, simple harmonic oscillator; rk4.c, rk4.f,

1 cycle theta vs t, realistic pendulum

1 cycle of theta vs t, anharmonic oscillator

Nearly chaotic, driven ball in box. (To Graph as Spectrum)
