How can the Human Body hear Sound?

1. The Sound Waves will hit your Ear Drum, which means it'll Vibrate 2. Those Vibrations are given to Tiny Bones [Ossicles] and then goes through the Semi-circular Canal, and finally the Cochlea 3. The Vibrations are turned into Electrical Signals, which is done thanks to the Cochlea 4. The Brain sees the Signal of the Sound as Different Pitches and Volumes; this is Dependent on the Frequency and Intensity. Higher Freq = Higher Pitch.
