Dangerous decibels

At  Dangerous decibels i learnt how to keep my ears safe from hearing loss. 1-6 people get hearing loss, when i turn 30 in will be 1-4 people. The ear is very complex in many ways. There are 10,000-20,000, little hairs in your ear these help you hear, if you wipe out to many you may lose your hearing for ever.

Sound is a vibration that turns into energy, today we used a tuning for and a ping pong ball to measure how much energy that goes to our ears.

We measure sound in a unit called decibels.
