Sound Design of Background Noise in the Electric Vehicle Interior Based on the Perception of Electric Vehicle Powertrain Noise

Abstract

A wide variety of automobiles have been developed in place of Internal Combustion Engine Vehicle, and in this study, we focused on the interior sound environment of Electric Vehicle, which is suggested to be the most popular in the future. Electric Vehicle powertrain noise such as motor noise and background noise such as road noise and window noise exist as noise perceived in the Electric Vehicle interior. In this study, the high-sensitivity parameters perceived from the sound quality evaluation based on the running condition are experimentally estimated, and the sound is designed by changing the frequency characteristics of background noise in the Electric Vehicle interior.
