Higher material density slows sound propagation speed
Evidence
In real materials the density of the material determines the effective mass of the golf balls. A higher density gives a higher effective mass and so the propagation will travel more slowly. — David Howard, Jamie Angus, coustics and Psychoacoustics, 33
