How do I do a simple particle diagram to show how ear defenders work???

Answer 1

My friend said you just say what the particles are like if they are tight together like solid or far apart like gas

Answer 2

I really don't understand this please can you give me an example? Am desperate!

Answer 3

well the energetical response from the ear drum bounces off particles from sound waves and catches responses that go to the brain. That is how we hear sound. Hear is some thing that could help you. Type up particle diagrams to show how ear defenders work. Thank me later
