Science of Music: Discovering Sound — page 1 — FEEL THE BASS N O I T C U D O R T N I It’s nice and quiet You’re about to write a paper for school But your brother has different plans He cranks up the stereo in his room The music radiates through closed doors and solid walls But the vocals are hard to hear You can’t quite make out what song it is 4

Science of Music: Discovering Sound — page 2 — Then the bass kicks in You not only hear it but you can also feel the sound The windows rattle Hanging pictures jiggle a little Even your chest buzzes with the bass It makes it hard to concentrate on homework What you hear feel and see comes from vibrating sound waves These waves travel from the stereo through your house The high notes move in shorter waves They can’t travel as far However low bass notes have much longer waves These waves move through thick objects such as walls As sound waves pass through matter they make objects vibrate The louder the sound the more movement the waves create
