Indoor sound pressure level forecasting: A geostatistical approach

Aim of the present study, is to identify, according to a geostatistical approach, a simple procedure to forecast spatial variability of noise emissions in order to evaluate sound pressure levels in each point of an indoor space. First step consists indeed in characterizing the indoor sound propagation according to a monitoring system: the number of measurements will be proportional to the complexity of the room to be tested. Then the mapping phase is realized according to a geostatistical approach based on the results of measurements. This discrete set of values represents the input data grid to be transformed into a continuous map. The study first part will refers about the F.A.I.K analysis according to the Kriging approach, based on a preliminary analysis of variograms. Then a comparison between sample measurements results and forecasted values will be showed.
