No frequency could be changed, the only effects you can expect is wavelenght and attenuation. Sound waves are dispersive meaning that high frequency attenuates closer due to several interference modes within the matter, temperature will affect the attenuation in some matters and affect wavelenght as far it affect density and elasticity of them.
