Audio Class: The Basics

The Nature of Sound

• Sound is produced by vibration
• Sound is waves in the air (or water!)
• Sound has pitch and loudness
• The waves can interfere with each other
  • They add or cancel
• The waves are directional
• High frequencies are more directional than low
• The waves can be reflected or absorbed...
  • Just like light
• Absorbed by just travelling through the air
