Speed of Sound in Solids Calculator

Find the speed of sound in a solid from its modulus and density.

Speed of sound 5,047.54

Formula: v = √(E ÷ ρ)

Step-by-step with your numbers:
1. Values used:
2. Young's modulus = 200,000,000,000 Pa
3. Density = 7,850 kg/m³
4.
5. Speed of sound = 5,047.54
Did we solve your problem today?

Sound travels much faster in stiff, light solids than in air.

The math behind it

For a thin rod, v = √(E ÷ ρ), where E is Young's modulus and ρ is density.

Worked example

Steel (E = 200 GPa, ρ = 7850) → about 5048 m/s.

FAQ

Why faster than in air?

Stiffer bonds transmit vibrations more quickly between atoms.
