These are what sound waves look like when drawn
The way we hear the sound is that the speaker and CD transmitts the data from electrical energy into sound energy.
Sounds are made through vibrations in the air particles when something is strum or made to vibrate it passes through the air as a wave.
This is how we hear noises. When a wave passes from one material to another at an angle, it usually changes speed, causing it to bend which is called refraction.
Sound waves can be measured with a machine called an oscilliscope which is where we connect the microphone, or in this case the CD player, to it and make some noise. It is then shown on the screen as waves and you are able to alter the pitch and volume
