Festuca - Pressure Waves lyrics
ad
The source of every sound is a vibrating body
Take for example a drum
The vibrating drum head
Pushes against the air every time it moves outward
We call these pulses of compressions and rarefactions
Pressure waves
A drum
Each sound has a distinctive pitch, loudness, and quality
Waves which your ears pick up and analyze
But first, let's investigate what causes sound
The source of every sound is a vibrating body
Take for example a drum
The vibrating drum head
Pushes against the air every time it moves outward
We call these pulses of compressions and rarefactions
Pressure waves
