This shows how air pressure changes over time. Tall waves = loud. Fast wiggles = high pitch.
This breaks sound into its component frequencies. Each bar shows how much of that frequency is present.
Pitch is how fast air vibrates. 440 vibrations/second = the note A. Double it (880 Hz) = A one octave higher!
Sound travels at about 343 meters per second in air - that's why you see lightning before you hear thunder!
Now you know that every sound - from a whisper to a symphony - is just vibrating air that your ears turn into experience.
Put your new knowledge into practice!
