Sound Pressure Spectral Density at 1 Hertz and 1 Hour Resolution Recorded at SanctSound Site PHRB_12_Part2

Metadata Updated: July 21, 2022

This record represents the sound pressure spectral density (PSD) 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 1800 seconds in each hour and converted to decibels (dB re 1 µPa^2/Hz). These data were recorded at SanctSound site PHRB_12 between October 15, 2018 and June 10, 2019, and represent 2 of 3 parts.
