The present paper reports the study of bulk properties ultrasonic velocity (C), density (ρ), refractive index (nD), adiabatic compressibility (β_a), specific acoustic impedance (Z) of a cholesteric liquid crystal cholesteric oleyl carbonate. The ultrasonic velocity, density and refractive index are measured for the sample in a temperature range 300 K to 320 K. With the help of measured data adiabatic compressibility and specific acoustic impendence have also been calculated.
