What does sound travel best through?

Answer 1

This may surprise you, but sound travels best through a solid, like wood. How to test it: First, get some kind of wood, such as a cutting board. then, put one of the flat ends up to your ear and rub the other side with your finger.

Water test: Fill your sink with water and get a stethoscope. Put the side that you check the heart with into the water and tap with your finger.

Air test: simply speak to someone from a distance of two meters.

DO NOT COPY! It would be rude to copy a nine year old's science experiment.

Answer 2

Sound is a travelling wave, which means it needs a medium to travel through -- it cannot travel through a vacuum. The implications of this are that, the denser the medium, the better, ie. faster, sound can travel through it. Generally, the more elastic a medium, the better sound travels through it. Elasticity is measured by how well a medium can return to it's original state when disturbed by a force, in this case, sound. Molecules in dense, elastic materials transfer energy more efficiently, so materials with low elasticity like gas, cork etc. are poor conductors of sound -- not ALL solids are good sound conductors.

In general, the speed of sound is proportional to the square root of the elasticity to it's density, but can change depending on ambient conditions, like temperature.

Answer 3

Sound's propagation speed depends on the type, temperature and pressure of the medium through which it propagates.

to make things easier sound waves travel easier through solids and liquids.

Answer 4

Sound travels best through solids because the particles are closely packed together, allowing vibrations to pass more effectively. Liquids also transmit sound well, followed by gases which are the least efficient medium for sound transmission.

Answer 5

Sound conductance is in part a function of density. Water conducts sound much better than air does.
