Abstract
Recently, due to the reduction of engine sounds such as electric cars, the background noise in the passenger compartment of road noise and wind noise tends to be relatively conspicuous. Therefore, in this study, we added pink noise simulating background noise and examined the recognition of engine sound during running. In this paper, following three studies will be discussed: (1) estimation of the effective frequency band for recognizing engine sound, (2) study of improvement of recognition by parameter change, (3) grasp of the relationship between engine sound recognition and driving performance using driving simulator driving task.
