hi, sound does travel through ground. the speed at which sounds travels depends on the medium. the denser the medium, the slower it travels and stiffer the medium, the faster it travels.
Sound waves can travel through different materials such as the ones listed here. However, their speed is what sets them apart. When sound travels through water, for example, it will travel faster than it does in the air. This is because the water molecules are placed closer together than air molecules, and can transfer sound waves more quickly. As a rule, sound travels slowest through gases, slightly faster through liquids, and fastest of all through solids. As with all science, there are exceptions to all rules. For example, some solids do not allow sound to pass through them at all. They are soundproof.
cloth can be made from alot of different things, but its usually made from wool, or cotton.
Wool and cotton.
Cotton And Wool
it is definately more than that in air 340 m/s
Cotton wool is not a conductor or an insulator it is a semi conductor. It is sort of in the middle, electrons can travel through cotton wool but not as good as silver, bronze, metal and so on.
Yes, gas can pass quite easily through cotton wool.

if i made ear defenders i would : Use foam because - it will absorb the sound Use rubber because - it has a lot of air bubbles in it. Sound takes a long time to travel through gases like air . Also some of the sound may reflect off the rubber. airpoo Vacuums, because sound travels best through air and there would be no air to travel through. And use cotton wool. : )
Believe it or not wool is a solid. Its fibers vibrate when sound approaches it therefor the vibrations are used up and there is less sound coming out from the other end of the wool fiber. (I'm Not Sure If Its Al Right But I Do Know that wool does absorb sound and It Can Be Used In Ear Defenders Or Ear Muffs To Cancel Out Noise).
is wool more absorbent than cotton
Cotton, They're soft than wool (i guess) but i choose cotton

yes. wool is from goats but cotton balls are made from cotton.

Cotton is a botanical product: wool is spun from animal fleece.
