Abstract: Abstract. The article analyzes the rules for processing measurement results expressed in decibels, present in the practice
of controlling the state of acoustic hazards in the environment. In particular, the problem of analyzing the possible
calculation errors that can occur in such processes is addressed. On the basis of numerical simulation experiments, the
possible level of errors that can occur in the operation of adding noise levels generated by two sources, in the situation of
coherent acoustic pressure disturbances, was checked.
