FIELD: computation engineering.
SUBSTANCE: method involves carrying out object-oriented measurement tract correction. To carry out it, some test signal frequencies are transmitted of given level in turn. Real level of the acoustic signals is measured at each frequency at their transmission place. The acoustic signal levels are compared to given levels at the same frequencies, measured acoustic signals levels deviations from the given ones are measured and frequency characteristic of the measurement tract is adjusted to compensate the difference between the measured and given acoustic signal levels at their transmission place.
EFFECT: high accuracy and reliability of measurements.
