Dangerous Decibels

Today we learnt about dangerous decibels, decibels are little tiny hairs in your ears that can be permanently damaged and can cause hearing loss. We did two tests, banging a tuning fork on the ground and listening to the vibration and tapping the forks on a ping pong ball. I learnt that 85 decibels (DB) is the safe limit that the sound should be and that headphones are more safer than earphones while listening to music and watching videos.
