	The paper formulates some objections to the results of the evaluation of uncertainty in noise measurement, which, are presented in two standards: PN-ISO 9612: 2004 and DIN 45641: 1990. In particular, it focuses on an approximation of the equivalent sound level by a function which depends on the artithmetic average of sound levels. Depending on the nature of a random sample the exact value of the equivalent sound level may be significantly different from the approximate one, which might influence on the erroneous estimation of the uncertainty of noise indicators. The article presents an analysis of this problem and the adequacy of the solution depending on the type of random sample.
