Data provided by National Oceanic and Atmospheric Administration
This record represents the octave band sound pressure levels (OLs) derived from raw passive acoustic data. OLs were calculated by integration of sound pressure spectral density estimates of the mean-square pressure with a 1 Hz/1 second resolution over 10 octave bands with the center frequencies ranging from 31.5 to 16,000 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 ��Pa). These data were recorded at SanctSound Site HI04_04 between January 03, 2022 and June 10, 2022.
