Hearing is like a sound journey that travels through your ear all the way to your brain. Everything that makes a sound — like a drum, a bell, or someone talking — causes the air around it to vibrate (shake).
These vibrations travel through the air like invisible waves. Sound waves enter your ear. Eardrum vibrates. Tiny bones move. Cochlea changes vibrations to signals.
Brain understands the sound. The sound we make is measured in decibels. How loud can you be?

Minnie - It was so much fun screaming at the top of our voices 😱🙀
Cheryll G. - Nightingales had lots of fun measuring the volume of quiet sounds and loud sounds. The results of the scientific work revealed that we are a "loud class" with voices that can reach 118.2 decibels. The teacher speaks at 65.39 decibels, while the class clapping collectively measured 132.98 decibels. Anything above 120 decibels is at the threshold of pain.
