Today we went to the "Dangerous Decibels" program which was run by Toni from some non-profit organization. Toni briefed us on the program and handed out a tuning fork and a pingpong ball with string mounted onto it. She instructed us to it the fork against the wooden floor and touch the pingpong ball. As a result, the pingpong ball bounced off of the fork due to the vibrations.
Afterwards, we learnt about safe and dangerous decibels. Decibels are what the volume of sound is measured in. A safe limit of decibels is 0-85, and anything over has a time limit. E.g: a washing machine is definitely safe to be around, unlike a bass drum of a drum set.
