Here are some interesting facts that you may not have know about Sound....


Sound comes from vibrations. These vibrations create sound waves which move through mediums such as air and water before reaching our ears.

Our ears vibrate in a similar way to the original source of the vibration, allowing us to hear many different sounds.

Dogs can hear sound at a higher frequency than humans, allowing them to hear noises that we can’t.

Sound is used by many animals to detect danger, warning them of possible attacks before they happen.

The loud noise you create by cracking a whip occurs because the tip is moving so fast it breaks the speed of sound!

Although music can be hard to define, it is often described as a pleasing or meaningful arrangement of sounds

Great post, I had no idea that music was just arranged sound and it wasn't created as music from the start!
