| Sound produces a relatively low level of energy when compared to other forms of energy. |
| Because sound produces such a low level of energy it is not used for electricity. |
| If the vibrational waves of a medium changes, the sound it produces will also change. |
| Sound is measured in decibels and pascals instead of the tradition unit of energy measurement, the joule. |
| The intensity of sound energy is usually measured using the perception of a normal hearing person. |
| The measurement of sound energy is related to its pressure and intensity. |
| We are able to hear different sound because as the sound (vibrations) enters our ear, the ear also vibrates. |
| Dogs' ears are more sensitive than human ears which allow them to hear sounds that humans cannot hear. |
| There is no sound in space because there is no object for sound to travel through. |
| Sounds travels through a solid much faster than through air. |
| 767 miles per hour is the speed of sound. |
| Sound travels faster through a liquid such as water faster than it travels through air. |
| Acoustics is the study of sound waves. |
| Flies cannot hear at all. |
| When whales communicate with each other under water, their sound can travel up to 800 km in the ocean. |
