FIELD: measuring equipment.SUBSTANCE: invention can be used for measurement of attenuation factor of ultrasonic waves in different media. Invention consists in that on first surface of sample is placed first converter, incorporated into connected to detector, amplitude of second bottom pulse, installed on opposite surface of sample coaxially to first second converter, not connected to detector, amplitude of first bottom second converter are connected to pulse detector instead of first without changing position of transducers relative to controlled sample, amplitude of first bottom pulse is removed from first sample converter, amplitude of second bottom and pulse ratio of measured amplitudes of value of attenuation factor.EFFECT: technical result is improved accuracy of measuring attenuation coefficient of ultrasonic waves.1 cl, 4 dwg |
