In fact, one of the recommendations by the American Academy of Pediatrics, Committee on Environmental Health was for NIOSH to examine further research on noise exposure during pregnancy. We are hoping that this study and these blog entries bring more awareness to everyone involved in the sport or any noisy activities so we can see improved safety and health practices in the near future. Earlier this year NIOSH scientists published the results of research on noise exposures at stock car events.1 Research conducted at the Brickyard at the Indianapolis Motor Speedway in Indianapolis, Indiana, the Bristol Motor Speedway in Bristol, Tennessee, and the Kentucky Speedway in Sparta, Kentucky, revealed that noise levels at these tracks often exceed those found in some of the loudest industrial settings. In fact, noisy conditions are not just a problem at NASCARthey are a problem at practically all motorsports. . Stay tuned for the third installment in our series on occupational noise exposures in sports and entertainment where we will address the risks of hearing loss and tinnitus in the music industry.
