SOUND LEVEL METER

This is a sound level meter. It tells you how loud what are you listening from your ears.

There will be some sound effect examples of each level of Decibels that will effect our hearing if you

use too much for your ears.

You will see a horn near the pictures and click it to hear the sound effect.

Enjoy the rest of slides of sound effect!!
