The contra-sounding principle is realized to improve the measurents of ultrasound velocity and attenuation in human bone.The velocity is independent from the test base length, recording the signals with respect to their arrival. The coefficients of variation of the velocity and attenuation for the bone specimens are 0.47 and 7.3%, for the tibia in vitro- 0.63 and 9.2%, in vivo - 0.69 and 10.4%,respectively. The attenuation tests halves the error at least. A fixed test base shall be used measuring the attenuation from the amplitude of the first half wave.
