In the current framework, hybrid and electric vehicles have the advantage of polluting the environment less than other conventional technology-based vehicles, nevertheless one issue of concern has been the noise impact that they generate.The main objective of this proposal is to improve the acoustic perception of the driver in the cabin. This is the reason why Transfer Path Analysis and Operational Path Analysis methods were performed in an electric vehicle. A comparison between both methods taking into account the structure-borne paths from the motor and the suspension points to the cabin has been performed. One of the aims of this study is to check the versatility of these methods, commonly used in petrol engine cars. This assessment includes the analysis of the noise contribution of each path depending on the frequency and vehicle speed range and moreover, the path noise impact for harmonic excitation due to the physical components of the electric vehicle.
