SOUNDS basics

SOUNDS

how does sound travel?

• sound is a form of energy. being able to hear sound is one of the most important senses. some of the sounds you hear are to loud and some to soft. this is the INTENSITY of the sound. sounds can also be high or low. this is the PITCH of the sound.
• sounds are made by something moving backwards and forwards. this is called VIBRATING. when you play the guitar the strings vibrate to produce a sound

• when sound travels through the air, the air particles squash up and move apart, just like the coils in a slinky.
• sound travels through liquid, solids and gases because the particles pass on vibrations sounds travel fastest through solids and slowest through gases
