Broadband Sound Pressure Levels at 1 Hertz and 1 Hour Resolution Recorded at SanctSound Site CI03 01
This record represents the broadband (BB) sound pressure levels (SPLs) derived from raw passive acoustic data. BB SPLs were calculated by integration of sound pressure spectral density estimates of the mean-square pressure with a 1 Hz/1 second resolution over the frequency band of 20 to 24,000 Hz. The result is then calcuated per hour as a median over no less than 1800 1-second values for that hour and converted to decibels (dB re 1 µPa). These data were recorded at SanctSound site CI03_01 between May 28, 2019 and October 6, 2019.
