One-third Octave Band Sound Pressure Levels at 1 Hour Resolution Recorded at SanctSound Site HI03_03

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 02, 2026 at 10:17 PM | Dataset Last Updated: June 15, 2023 at 12:00 AM
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 HI03_03 between November 30, 2020 and May 07, 2021.
