a
  • Sound waves
  • Transfer energy by vibrating
  • particles of matter
  • b. Cannot transfer energy
  • through matter
  • c. Can transfer matter but
  • not energy

Caused by long term exposure To loud
sounds ___________________________
  • 3,4

15
c. By vibrating objects
  • How is sound energy produced?
