Summary:

The object of engine nacelle noise prediction is to use aircraft sound data measured at a test site or measured from flyover data and estimate the noise level as a function of time at other hypothetical observer locations.The simulation consists of applying attenuation corrections to the input sound pressure spectra to obtain the projected spectra as a function of time.The effect of acoustic noise suppression can be analyzed by examining the influence of each noise source on the total noise spectra.Trade studies can be conducted by constructing lines of constant annoyance for aircraft landing, takeoff, or fly-by
