The Science of Sound

Vibration

• Sound is produced because of vibrations.
• When an object vibrates, it creates sound waves that travel through a medium (air, water, etc.) to reach our ears.

Frequency

• Frequency is the number of vibrations per second.
• A faster vibration produces higher frequency, resulting in a higher pitch of sound.
  • Example: Tightening the tuning peg of a Sitar increases its tension and vibrating frequency, resulting in a higher pitch.

Timbre

• Timbre refers to the ‘tone' or 'colour' of the sound.
• Timbre varies with the material used for the instrument, construction of the instrument, and its playing technique.

Resonance

• Through resonance, sound is amplified or made louder.
  • Example: In a percussion instrument, the hollow body or cavity resonates, amplifying the sound.
