Visualization of Vehicle Sound Quality Using Human Hearing Model 940604

The purpose of this study is to develop a method for analysis and evaluation of vehicle sound quality that replicates the human hearing sense.
First, a method for analysis using a human hearing model was developed, and the results of the analysis were expressed as an image. Second, a method for objective evaluation of vehicle sound quality was developed, based on subjective evaluation tests, and the evaluation result was expressed as an image and number. These results reflect the properties of human hearing, enabling intuitive recognition of vehicle sound quality. Therefore, this is applicable to sound quality comparison and interior sound quality design.
