Why does sound travel better through solids but it is dampened when it finds a wall?

Question

I have been taught that a solid state medium helps the vibrations of the particles traverse better through it than in a gas state medium, so why a sound wave travels through air but it stops when it finds a solid object like a wall?

Answer 1

Because most of the sound bounces off said wall instead of traveling through it. A little will make it through the wall, which is the reason the volume decreases
