depends :
Newton-Laplace equation
cs= (G/rho)^0.5
cl = ((E(1-v))/(rho(1+v)*(1-2v)))^0.5
for gases:
c = (gama*R*T/M)^0.5
where c = speed of sound
cs = shear speed of sound
cl = longitudinal speed of sound
G = coefficient of stiffness (bulk modulus for gases)
E = modulus of elasticity
v = poissons ratio
rho = density of the material
gama = adiabatic index 91.4 for most diatomic gases at room temperature)
R = molar gas constant
T = temperature
M= molar mass
so for say Aluminum
G = 3.8*10^6 psi
E = 9.9*10^6 psi
v = 0.3
rho = 0.098 lb/in^3
cs = 6227 in/s
cl = 11661 in/s
so in Mph:
cs = 354 mph
cl = 622 mph
aluminum is a fairly soft solid so the speed of sound is low but the stiffer the material the faster the speed of sound
Sound cannot travel through a vacuum as it needs a medium, such as air, water, or solid material, to propagate. In a vacuum, there are no particles for sound waves to travel through, so the speed of sound is essentially zero.
Sound waves travel faster through solids than through liquids or gases, with speeds ranging from around 2 to 15 km/s depending on the material. The speed of sound in a solid is determined by the material's elasticity and density.
Sound travels faster in solids because the particles in a solid are closer together and tightly connected, allowing vibrations to pass quickly from one particle to another. This direct and efficient transfer of energy between particles enables sound waves to move rapidly through a solid medium.
You'd have to say that the speed of sound waves in vacuum is zero, becausesound can't travel through vacuum at all. Not even an inch. Sound needs amaterial substance to travel through.
Because waves, such as sound, need to travel through a medium, whether it be water, air, etc. Since in empty space, there is no air, therefore there is no medium to travel in, so sound cannot travel.Sound waves require a medium (solid, liquid or gas) to travel through. They do this by alternately compressing and rarifying the distanced between the atoms or molecules of the medium.

depending on the nature of the solid liquid or gas. usually gas the fastest followed by liquid than solid.

All the molecules are packed in tight and in an orderly fashion so the sound can travel faster through it. Gases have molecules away from each other so the sound cannot be passed through the vibrating and bouncing molecules so well.
The rate at which sound travels through stone depends on the stone. Sound will travel faster through warm stone than cold stone.
