Sound Pressure Spectral Density at 1 Hertz and 1 Hour Resolution Recorded at SanctSound Site CI05_08

Published by NOAA National Centers for Environmental Information | U.S. Census Bureau, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-04-15T00:00:00.000+00:00
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 20 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 CI05_08 between July 07, 2021 and November 12, 2021.
