Sound Pressure Spectral Density at 1 Hertz and 1 Hour Resolution Recorded at SanctSound Site SB03_21

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 05, 2026 at 08:53 PM | Dataset Last Updated: August 28, 2023 at 12:00 AM
This record represents the sound pressure spectral density (PSD) levels derived from raw passive acoustic data. The hourly PSD levels were calculated as the median of mean-square pressure amplitude (µPa^2) with a frequency resolution of 1 Hz from 10 Hz to 24,000 Hz over no less than 1,800 seconds in each hour and converted to decibels (dB re 1 µPa^2/Hz). These data were recorded at SanctSound Site SB03_21 between April 22, 2022 and June 13, 2022.
