Sonification: Auditory Graphs

(OSU Physics: S. Sahyun, J. Gardner)

• Map: Pitch (frequency) -> ordinate (y) vs Time -> abscicca (x)
•  
• Hear points (1,1) and (2,4):
• Hear a straight line
• Hard to distinguish y = x from y=x²
• Add "drum" beat:
  • slope dy/dx : number of drum beats
  • curvature d²y/dx²: pitch of beat
• y=x² (+ curvature, low f beat)
• y=sqrt(x) (- curvature, high f beat)
• Gaussian
