摘要：
FIELD: measurement technology.SUBSTANCE: invention refers to methods of assessing human life safety, namely to methods for assessing acoustic safety of human vital activity. Method of acoustic safety assessment consists in the fact that according to the acoustic environment parameters measurement results the Δ1 is difference between actual and maximum allowable value of equivalent sound level A per working shift, Δ2 is difference between actual and maximum permissible value of maximum level of sound A, measured with time correction "slowly" equal to 1 s, Δ3 – difference between actual and maximum allowable value of maximum level of sound A, measured with time correction "pulse", equal to 40 ms, Δ4 is difference between actual and maximum allowable value of peak sound level corrected on scale "C", Δ5 is difference between actual and maximum allowable value of equivalent total infrasound level per working shift, Δ6 is the difference between the actual and the maximum permissible value of the maximum total infrasound level, measured with time correction "slowly" in frequency range 1.4…22 Hz, Δ7 is difference between actual and maximum allowable value of equivalent level of sound pressure per working shift in octave frequency band 2 Hz, Δ8 – difference between actual and maximum allowable value of equivalent level of sound pressure per working shift in octave frequency band 4 Hz, Δ9 is difference between actual and maximum allowable value of equivalent level of sound pressure per working shift in octave frequency band of 8 Hz, Δ10 is the difference between the actual and maximum allowable value of the equivalent sound pressure level per working shift in the octave frequency band of 16 Hz, Δ11 is the difference between the actual and maximum allowable sound pressure level in the octave frequency band of 31.5 Hz, Δ12 is the difference between the actual and maximum allowable sound pressure level in the octave frequency band of 63 Hz, Δ13 is difference between actual and m
