Listen Up Folks!

Last week we were lucky enough to have some Lynfield College students come and teach us about sound. We learnt about decibels and how loud is too loud for our ears!  

To prove some of these ideas about sound, we created a model of an ear drum using a cup, balloon and a rubber band. We carefully sprinkled some salt on the stretched balloon. Then we made a variety of loud and soft noises. We had to carefully observe what was happening to the salt.

What do you think happened?  We even used the UE BOOM to play loud music to see what happened to our model ear drums.
