When a brass rod is encased in aluminum its speed of a sound wave increases when it passes though the rod and moves from the brass into the aluminum.

speed of sound in solids > speed of sound in liquids > speed of sound in gases.

So, sound travel faster in solids because the molecules are more closer in the solid state.

solid and liquid are less compressible than gas so liquids and solids have much greater bulk modulus than that of gases.

Thus the speed of sound increases when it travel from gases to solids state.
