Why does Sound travel faster through air than through wood?

Answer 1

It doesn't, sound travels faster through wood. The more dense the material the better the sound carries. Because wood is more dense than a gas such as oxygen the sound travles faster through the wood.

Answer 2

Sound travels faster through air than through wood because air is less dense than wood, allowing sound waves to propagate more quickly. In wood, the molecules are closely packed together, causing sound waves to travel at a slower speed due to increased resistance and energy loss through collisions with the material's particles.
