• Acoustics is the study of sound waves.

  • 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 pascal instead of the tradition unit of energy measurement, the joule.

Sound Energy Facts

  • 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.

 

 

Sound Energy Facts

  • 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.

  • When whales communicate with each other under water, their sound can travel up to 800 km in the ocean.
