Sound always need a medium to travel whther it be solid, liquid or gas. If we use several layers to build a shield, sound may not be able to penetrate. But it depends on the nature of the sound too. The audible sound which we can hear will not able to penetrate through several layered structures. But high frequency ultrasonic waves can penetrate even cement blocks.
Denser material, higher speed.
medium
sound
Everything. We're all a vibration.
sound waves
Denser material, higher speed.
The sound is made of vibration so as it moves, it vibrates the material to carry the sound. This also depends on what kind of material.
outer space because you need some kind of physical material for sound to travel through and there's none of that in space
sound energy require some kind of material to travel through and they cant move through a vaccum
medium
Sound travels through matter as transverse pressure waves.
sound waves?
sound
No. The rate of the vibrations is the 'frequency' of the sound, and that doesn't change, no matter what kind of material the sound is traveling through. Sound travels faster through steel than through water or air because the steel is more dense.
sound waves..
Sound cannot travel through a vacuum, scientific or any other kind
Sound waves and gamma rays.
