    • Octave Band Sound Pressure Levels at 1 Hertz and 1 Hour Resolution Recorded at SanctSound Site PHRB_12_Part3

    Metadata Updated: July 21, 2022

    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 1800 1-second values for that hour and converted to decibels (dB re 1 µPa). These data were recorded at SanctSound site PHRB_12 between October 15, 2018 and June 10, 2019, and represent 3 of 3 parts.
