Sound
by Jared Rovny, PhDSound waves are effectively colliding vibrating particles that create a sort of chain reaction, causing more and more particles to vibrate and knock into other particles. This is how sound waves travel away from their source. We hear sounds because the vibrations in the air cause our eardrums to vibrate, and these vibrations are converted into nerve signals that are sent to the brain. Similarly, microphones detect vibrations in the air and convert them into electrical signals. This course covers the phenomenon of sound, including its basic properties and important dynamics.
