Frequency spectra: in-situ method for sound insulation for post (prEN 1793-6)

In this section the frequency spectra in 1/3 octave band for the collected data are shown. For confidentiality reasons only averaged data can be shown in the public database. As the information on the frequency spectra was not always present, the diagrams in this section contain data related only to measurements methods and data for which this information was available. For each measurement method where spectra were available an interactive diagram is displayed. You have the choice to see the all the averaged data together or to select only one barrier material. The grey area represents the 95% confidence interval of the values currently displayed.
