How does density generally affect sound speed when comparing materials of similar elasticity?

Answer

Sound travels slower because heavier particles take more energy and time to move.

Increased density means the particles are heavier, requiring more energy and time to respond to the arriving acoustic disturbance, thereby slowing propagation if stiffness is held constant.
