The speed of sound is an important property of an equation of state (EoS): depending on the setting for various reasons. In the context of neutron star (NS)/ nuclear EoS the speed of sound is a measure of stiffness of an EoS: a stiff EoS (an EoS with a high sound velocity) generates a high pressure at given energy density.
