It stands to reason that drivers who take part in any kind of motorsport are putting their lives at risk in some way. Apparently, though, even being a fan of NASCAR can be hazardous to your health. And it's not because the cars sometimes find themselves barreling off the track and into the crowds.
According to a recent study, noise levels at Indianapolis Motor Speedway, Bristol Motor Speedway in Tennessee and the Kentucky Speedway can reach alarming levels – as high as 140 decibels, significantly louder than a jet at takeoff. By way of comparison, the Occupational Safety and Health Administration (OSHA) has set the maximum allowable noise levels over an eight-hour work day at just 85 decibels.
It takes just one minute for drivers and under an hour for workers and spectators to hit OSHA's maximum allowable noise level for the entire day. Worse yet, it seems that the damage caused by such high noise levels adds up over time and is not reversible. That said, nobody is suggesting that sporting events like NASCAR should be banned. Instead, the study aims to inform people of the risks and urges them to take appropriate action... in other words, ear plugs are your friend.
