Compressional and shear wave velocities and attenuation in sintered magnetite were accurately measured to investigate the Verwey transition by the pulse transmission method using a dual acoustic path across the temperature range between 78 K and 300 K@. The temperature dependence of the compressional and shear wave velocities of the sintered magnetite exhibited a steep depression at ${\sim}\,90$ K@. The low transition temperature suggests nonstoichiometry of the present sintered sample. Using the measured ultrasonic data, the elastic properties of sintered magnetite are discussed.
