Question

Hello :)
For my assessment tomorrow, one of the things I have to think about is this:
"Explained how the ear defenders will work using the Big Idea of Energy Transfer."
I have no idea about this at all, please help!

No I mean we have to design ear defenders, and this is one of the things we have to do. We haven't even learnt about this big idea of energy transfer, so I'm really confused :\
