Dataset of airborne sound power levels and third octave band spectra of passenger ships across different operational phases in the port of Split

The present dataset reports the results for airborne sound power levels and third octave band spectra of passenger ships across different operational phases in the port of Split. The results are obatined after multiple measurements conducted in May 2024 by qualified personnel with Class-1 instrumentation under favorable meteorological conditions and processed following the guidelines reported in doi:10.1016/j.heliyon.2022.e09021 The uncertainties are calculated as standard variation over the multiple measurements of each event (at least 3). A-weighted sound power levels and third-octave spectra were derived for ferries, cruise ships, and catamarans during key operational phases: hotelling (at berth), loading/unloading, arrival, and departure.
