Abstract [en]

In the paper the influence of the measurement time on the measurement uncertainty of environmental noise is explored. An original procedure based on a bootstrap method is introduced to determine the minimum measurement time, which takes into account the statistical variability of the acquired sound pressure levels. The experimental verification against real data about three different environmental noise sources shows the reliability of the algorithm for the prediction of the short-term noise indicator corresponding to longer time window.
