Importance of sound or noise in safe driving cannot be ignored alongside other psychological effects. Personal subjective representative noise tests are conducted as part of rating new vehicles. But these tests are done mostly to trace intrusive noises like engine noise at constant road speed or while accelerating, and aerodynamic noise in the cabin. In-cabin noise sources like the HVAC system flow are generally not considered in these tests. |
