Sound Energy Facts

Sound Energy Facts
Sound energy is a form of energy that is associated with vibrations of matter. It is a type of mechanical wave which means it requires an object to travel through. This object includes air and water. Sound originates from the vibrations that result after an object applies a force to another object.
Interesting Sound Energy Facts:
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.
