What is Sound (Frequency) – A Simple Analogy
June 12, 2024An easy way to think of sound is pulses of air reaching your ear. Sound has a frequency or frequencies. Frequencies are the time delay between each pulse of air.
These pulses of air are caught by the ear drum which converts the time between pulses into a signal which the brain identifies as a sound frequency/tone.
The loudness of the sound is determined by how strong each pulse of air is. Weak pulses, low volume, strong pulses, high volume.
Strong pulses cause the ear drum to move more than weak pulses. The ear converts the amount of movement into a signal the brain understands as volume.
