Abstract

The difference between a measurable value and a threshold does not involve a straightforward comparison of values, given that such a measurement result has to be expressed in a manner consistent with the principle of the ISO Guide to the Expression of Uncertainty in Measurement (GUM). In the other words, the uncertainty of the measured value has to be taken into account. Such matters are highly relevant to the area of the measurement of relative levels of environmental noise from the perspective of providing an adequate estimate of the indetermination associated with such measurements. Here it is necessary to account for the uncertainty that appears around particular noise events. The intention of the first phase of this study is to eliminate outliers that occur when measuring signals in real time. Then the second phase will determine the uncertainty associated with the measurement of purified signals.
