Scientists from the Centers for Disease Control and Prevention's (CDC) National Institute on Occupational Safety and Health (NIOSH) have measured sound at the race car track up to 140 A-weighted decibels (dBA) in the pits, with levels at 96 dBA in the stands and 114 dBA for drivers. These drivers have detailed conversations while you assert they should be writhing in pain. Decibel Level is a multiplier that will help you determine the effect of volume on your hearing. If mufflers are not used to reduce noise from race cars to a TWA below 85 dBA, then hearing protection must be used. For many vehicles, the road contact noise will be larger than the noise from engine or exhaust.
