Dangerous decibels

In today's lesson we had learnt what a dangerous decibel was and a safe decibel was. Since this lesson I will be changing the way I listen to music,talk,play and what kind of environment i'm in. During this lesson I had learnt what a decibel was, It is a way of measuring sound. One fact that I have learnt is that Birds, Frogs and Fish can grow their ear cells back unlike humans that can not, Meaning if you lose your hearing then you don't get it back.

Anything over 90- 120 Is a dangerous level of decibels to be listening to. If you are listening to anything that could make this sound then you need to be cautious of how long you are listening to it for.
Washing machines, Food mixers, Piano playing or rain Is a safe sound to be hearing.
Car traffic decibels are most likely 85 decibels, So you should only be in traffic noise for about 8 hours.
Motorcycles and power tools are 100 decibels, 15 minutes is max.
Mp3 players at it's full volume is 110 or a band practice, 2 minutes is a safe time to be listening to it.

If you listen to these sounds longer than recommended it may cause hearing loss.

We got to experience sounds frequencies and games to show what it's like to have hearing loss.

After this lesson I will now turn down my volume and keep my environment quite.
