Assessment of in-cabin noise of wide-body aircrafts

•Provided an extensive data set of in-cabin noise measurements in six different aircraft models while in operation.•The noise measurement has been performed in medium-haul and long-haul flights.•The sound pressure levels of in-cabin noise have been measured on two different decibel scales, namely, A-weighted [dB(A)] and C-weighted scales [dB(C)].•The results confirmed the quietest aircraft, as claimed by some published reports.
