Using Sound for Data Presentation

• Associate a sound with a data point
• Attributes of sound are controlled by data values
• Trigger the sound on some event

This is sonification

Judging Aural Stimuli (Miller 56)

• Pitch - 6 levels
• Loudness - 5 levels
• Pitch and loudness - 9 levels (not 30)

Again, our ability to distinguish a wide variety of sounds and voices requires either a large number of features or a significant amount of training (for example, people with perfect pitch)
