Neither is asking your friends to repeat everything they say because you didnt make out the words the first time. Based on anecdotal discussions with teams and drivers, experiments with noise cancellation systems have not proven very successful or desirable, mostly because drivers (and their crew) need to be attuned to any small changes in car and engine performance that the noise cancellation system may potentially mask. From available data, NASCAR (National Association of Stock Car Racing) have shown noise levels significantly higher than the acceptable occupational daily dose of 85 dB as summarised in Table 1 [2].Noise levels in a Formula 1 (F1) event can go up to 140 dB, enough to cause permanent hearing loss [3].This sustained over an entire race event is well above the HSE (Health and Safety Executive .

While I agree that noise is an essential part of NASCAR, I am glad to see that somebody is taking note of the harmful effects NASCAR has on our health!!! You can measure them with a sound level meter, also known as a sound pressure level meter (SPL). Most spectators assume that a few hours of recreational noise exposures are harmless, but noise exposures do add up and data from our research show otherwise. No, every three decibel increase marks a 100 percent change in sound pressure. Down at the road and inside the cars, the sound level can reach 130 dB. Through the NIOSH Health Hazard Evaluation program we can consider requests from workers, employers, or worker representatives to evaluate noise levels that may put workers at risk.
