A few weeks ago Tracey from the Hearing Association came to school to talk to our class about dangerous decibels. She told us we should either turn it down, walk away or wear ear plugs or ear muffs. We learnt all about the hair cells inside our ear and that once we have damaged them we can't fix them. At the end of the lesson we all got to have a god with some tuning forks, We loved going around hitting everything and listening/seeing them vibrate. Tracy gave everyone in our class some ear plugs so we can protect our ears.We had a great time with Tracy.
