METHOD MEASURING SOUND PRESSURE OF LEAK IN TESTED OBJECT AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: measurement technology, test of leak-proofness of examined object, specifically, steam and water pipes in atomic power station and in similar industrial facilities. SUBSTANCE: level of acoustic noise in the form of sound or pulsating pressure and its spectral characteristics are controlled parameters. In this case distances between sensors and sources of leak ( damage ) are found when no reflection from local things and room are present. Level of sound pressure is measured at point of leak in closed small and large rooms with due account of reflection and reverberation phenomena occurring in room. EFFECT: location of emerging leak in object. 2 cl, 4 dwg
