One-third Octave Band Sound Pressure Levels at 1 Hour Resolution Recorded at SanctSound Site GR03 02
This record represents the one-third octave band sound pressure levels (TOLs) derived from raw passive acoustic data. TOLs were calculated by integration of sound pressure spectral density estimates of the mean-square pressure with a 1 Hz/1 second resolution over 30 one-third octave bands with the nominal center frequencies ranging from 25 to 20,000 Hz. The result is then calculated per hour as a median over no less than 1,800 1-second values for that hour and converted to decibels (dB re 1 µPa). These data were recorded at SanctSound Site GR03_02 between May 02, 2019 and September 09, 2019.
