%X We study the mechanical properties mixture compounding rubber with different ratios concentration of PbO , by using ultrasonic measurements of fixed frequencies (26 kHz) , these properties are ultrasonic velocity, compressibility , specific acousticimpedance , relaxation time, bulk modulus, Results show that all these properties were decreasing with increasing the concentration of PbO in the composite , this reason made these values reduced except that scattering were dominate so we pointed that this composite more effective to reflect and scattered ultrasonic waves.
