Properties of Sound

Examples of sound are: music, bangs, and siren.

A property of sound would be that the volume of the sound can change depending on the distance the sound is from the source. The closer sound was higher on the decibel meter and the further sound meter was lower. 

The last property observed of sound is that sound can travel corners.  

This is because Mr Wong clapped in another area of the classroom and the meter was still able record the sound.
