    Quality and refinement are of paramount importance
    for luxury vehicles. The rapid electrification of the
    automotive industry has increased the contribution
    of aeroacoustics to the consumer perception of sound quality.
    The ability to predict whole vehicle aeroacoustic interior noise
    is essential in the development of vehicles with an extraordinary
    acoustic environment.
    This publication summarises the development of a process
    to combine lattice Boltzmann computational fluid dynamics
    simulations, with a whole vehicle statistical energy analysis
    model, to predict the aeroacoustic contribution from all
    relevant sources and paths. The ability to quantify the relative
    contribution of glazing panels and path modifications was
    also investigated.
    The whole vehicle aeroacoustic interior noise predictions
    developed, were found to be within 2dB(A) of comparable test
    vehicle wind tunnel measurements, across a broad frequency
    range (250-5000Hz). The ability to determine panel contributions
    and identify the effect of path modifications was
    also shown.
    This study is the first stage in delivering an accurate, optimised
    and cost effective approach to predict whole vehicle
    aeroacoustic interior noise, early in the vehicle development
    process; reducing the reliance upon expensive
    prototype vehicles.
