dangerous decibels

On Tuesday we met a lady called Tracy. She talked about our hearing. There was a tool called a tuning fork. If you hit it on something hard and put it on something it made sounds. There are some things in your ears Tracey called them soldiers and if you listen to something loud some of them will die. When all of them die you they will not grow back. You could be deaf for the rest of your life. Scientists figured out that frogs, birds, and fish are the only living thing that grow them back in the whole entire world!
