In gas: u = √(γP/ρ), where γ is the specific heat ratio, P is the pressure, and ρ is the density

In solids, for longitudinal waves: u=√(G/ρ), for transverse waves: u=√(E/ρ), G is the shear modulus, E is the elastic modulus, and ρ is the density. The formula for calculating the speed of sound is: V=S/t. Where V is the speed of sound, in m/s; S is the distance, in meters (m); t is the time, in seconds (s);
