  1. 16. Experimental Study of Installation Effects on Cooling Fan Noise

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Yu-Yu Lu; [2021]
    Keywords : Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

    Abstract : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources.
