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 1800 1-second values for that hour and converted to decibels (dB re 1 µPa). These data were recorded at SanctSound site CI05_01 between November 1, 2018 and February 4, 2019.

    • Sound Monitoring
      NOAA and the U.S. Navy are working to better understand underwater sound within the National Marine Sanctuary System. For the next few years, these agencies will work with numerous scientific partners to study sound within seven national marine sanctuaries and one marine national monument, which includes waters off Hawai'i and the east and west coasts. Standardized acoustic measurements are used to assess sounds produced by marine animals, physical processes (e.g., wind and waves), and human activities. Collectively, this information will help NOAA and the Navy measure sound levels and baseline acoustic conditions in sanctuaries. This work is a continuation of ongoing Navy and NOAA monitoring and research, including efforts by the NOAA Office of National Marine Sanctuaries.

Processing Steps
  • One-third octave band sound pressure levels (TOLs) in units of µPa^2 were calculated by integration of sound pressure spectral density estimates of the mean-square pressure (µPa^2) with a 1 Hertz (Hz)/1 second resolution over each of 30 one-third octave bands with the nominal center frequencies ranging from 25 to 20,000 Hz (IEC 61260-1995). The resulting TOLs with the 1 second resolution were then used to calculate hourly TOLs as a median over no less than 1800 1-second values for that hour. The TOLs per hour were converted to decibels (dB re 1 µPa).
  • Data were processed with Triton - Soundscape Metrics Remora (Github commit '44f0f20'; Feb 9, 2020) and Matlab (2016b and newer; statistics toolbox).
