FIELD: physics.
SUBSTANCE: method includes picking up structural reverberation noise on a background of echo signals received from possible defects and picking up intrinsic reverberation noise of the flaw detector and inspecting the contact between an electroacoustic transducer and the material under investigation by comparing the amplitudes of reverberation noise on a background of echo signals received from possible defects and intrinsic reverberation noise of the flaw detector.
EFFECT: high reliability of inspecting quality of acoustic contact.
