Yes. Sound requires a medium to travel in.

It is comprised of pressure waves (a mechanical phenomenon). Sound requires something to compress and rarefy (a medium). Sound pressure, or acoustic pressure, is the local pressure deviation from the ambient (average, or equilibrium) atmospheric pressure.

Sound pressure can be measured using a microphone in air and a hydrophone in water. The SI unit for sound pressure is the pascal (symbol: Pa). The effective sound pressure is the root mean square of the instantaneous sound pressure over a given interval of time (or space). Sound can't travel in a vacuum because it lacks the necessary medium.

What is mechaincal energy?

The form of energy that needs a medium to travel is known as mechanical energy.For example sound needs a medium to travel,that's why sound can't travel in vacuum,light needs no medium to travel it is non mechanical form of energy.


Sound will NOT travel through?

Sound needs a matter based medium, so it will not travel through vacuum.


Where does sound not propagate?

sound needs a material medium to travel. Sound can travel by compression and rarefactions.attma


Where do sound waves cannot travel?

it can't travel in a vacuum, it needs medium to travel


Since sound is a mechanical wave sound needs a what to travel through?

Sound needs a medium to travel through. This medium can be air, water, or a solid material like metal. Sound waves transfer energy by vibrating particles in the medium they are traveling through.


Does sound travel in vaccum?

No, sound cannot travel in a vacuum because it requires a medium (such as air, water, or a solid material) to propagate. In the absence of a medium, there are no particles for sound waves to travel through, so sound cannot be transmitted.


What waves needs a medium to travel through?

Sound Wave


What does sound travel as in a medium?

It needs particles, so Air, Liquid or Solid to travel. so the medium is any particles, so if there is no particles, sound cannot travel.


Which can sound NOT travel through?

Vacuum as sound needs badly a material medium to get it propagated.


Why are sound waves not considered a mechanical wave?

Mechanical waves are waves that require a medium in which to travel, i.e., a solid or fluid. As sound needs a medium to travel, sound is a mechanical wave.


Why can't sound travel easily through some materials?

Sound needs a medium to travel. It cannot travel through a vaccum.


What factors are necessary for a sound wave to travel through a medium?

well sound actually always needs a medium so it can travel, in space there's is no sound because there isn't a medium it can travel through. but just about anything is a medium for sound. air is also a great medium, that's why were able to hear one another
