Explaining how ear defenders work using the big idea of energy transfer?

  • Science - , Wednesday, February 17, 2010 at 6:15pm

    Is that something a sparring partner wears in boxing? Or something you (should) put in your ears at rock concerts?

    Is this a question from some sort of home study science course?

    Just what is the "big idea of energy transfer" ?
