Broadband Sound Pressure Levels at 1 Hour Resolution Recorded at SanctSound Site PM08_12

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-06-15T00:00:00.000+00:00
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 calculated per hour as a median over no less than 1,782 1-second values for that hour and converted to decibels (dB re 1 µPa). These data were recorded at SanctSound Site PM08_12 between October 15, 2018 and June 10, 2019.
