Abstract
The suitable choice of the minimum measurement time window is fundamental for a precise evaluation of environmental noise. This work aims to analyze environmental noise in the frequency domain by using a statistic technique, named bootstrap method. This procedure, already experimentally validated in the time domain, was also applied in the frequency domain and subsequently the measurement times obtained in the two respective domains were compared, providing positive results.
