Document Summary

Every time you speak, you speak with many frequencies: the main ones are red, but there are other higher frequencies included to give you the tone of your voice. The flute playing: notes climbed up and down. Do not hear the pitch itself it is which neuron is firing that gives you the. The loudness is how much each of these neurons fire: fire a lot = louder, tell the brain how loud the sound is at that frequency. Our sense of hearing is often underappreciated. People who lose hearing feel very isolated from the world, and most importantly the company of people. Sound is produced when something vibrates, like the speaker in your stereo: when the speaker pushes on the air, it compresses it. Heard nothing when the speaker started to vibrate: 2. Took time for the waves (air that compressed, air got verified less dense) to move into.
