This program is about the how we can protect our ears from going deaf.
(dB = Decibels)
The safe level is 85 dB. If it is higher than 85 dB there is a time limit that you should use I for.
The most fun about this program was a thing called a Tuning fork.
This is because went it hits the ground it makes a vibration and makes a high sound. Some people use it to tune there guitar.
I learnt how they measure sound.
