Today in 2nd block we went over to the otherside of the school and learnt about the dangerous decibels programme about hearing. I learnt that 85 decibels is the most you should be listning to when or where ever you are. If you find that it is over 85 decibels you will loose you hearing over time.
First we got cards and we had to guess if the picture on the card was safe or dangerous. Most of them were dangerous. Then we got a tune fork and knocked it on the ground and put it up to our air, it viabrated, then we banged it on the ground again and put it on our hand. Then we banged it on the ground again and put a pingpong ball with string on it, the teacher said that that was the decibels of a rock concert which can defin your hearning in 15 seconds and the decibel of it is 120.
We got taught about volume on ipods and laptops and you should never have your sound full volume because it can damage your hearing in about 2 minutes and it is 110 decibels. So when I get home I am going to change my laptop and Ipod volume to below halfway.
Interesting Fact - When Frogs lose part of their hearing they can actually grow it back.
Something I learnt - 85 decibels is the most you should be listning too or hearing.
Something I am going to change - Turn down my ipod and laptop sound when I have my headphones in.
