Today our class went to met Toni who talked to us about Dangerous Decibels and how loud noises can affect our ears. Noises are vibrations the human limit is 85 decibels.
We learned that if you have your headphones in at the the high volume you get up to 110 decibels! Then we got a tuning stick and hit it on the table and put it to our ears and heard the vibrations, then we got a ping pong ball and held it up and hit the tuning skite on the table and put it next to the ping pong ball and it bounced of it.
