  16. 16. Particles vibrate perpendicular to the direction that the energy travels
  17. 17.  Sound travels faster in higher temperatures In a vacuum sound waves cannot travel because there are no particles to carry them Sound waves are produced in musical instruments and voices by objects and air vibrations Things that vibrate make sounds
  18. 18.  The pinna (the large flap of ear we can see) collects the sound waves and then these pass through the ear canal until they reach the ear drum. The ear drum vibrates and pass the sound waves into the middle ear. This meets three small bones called the ossicles that transmit sound very efficiently. The vibrations from these bones are passed through the fluid in the cochlea and make tiny hairs move. When the hairs move they cause an electrical signal to travel through the auditory nerve and send a message to the brain. Your brain makes sense of the signal and you can hear the sound.
