What's the NRR? WHO CARES! The doseBusters technology makes all laboratory measurements of hearing protector attenuation and all population-based estimates of hearing protector effectiveness absolutely obsolete. Hearing conservation is reduced to an individual level, making these inaccurate guesses unnecessary. Is regular hearing protection good enough? Yes. Moderate attenuation hearing protection, when worn effectively, provides enough attenuation to reduce nearly all industrial exposures to a safe level. With the doseBusters methodology, quantitative data is supplied to ensure that the HPDs are worn effectively. The continual efforts of hearing protector manufacturers to achieve higher and higher NRRs is purely a marketing exercise and has absolutely nothing to do with preventing hearing loss. Why put the doseBusters dosimeters on everyone? Hearing protector effectiveness is highly variable across wearers. The attenuation provided by a HPD can vary by 40 dB between two individuals. In addition, hearing protector wearing habits and noise exposures vary widely across individuals. Why require sampling every day? Every day with hearing protection is a new experience. Sampling one day does not ensure that the HPDs will be worn effectively the next day, or the day after that. Also, liability for hearing loss compensation is reduced or eliminated if management has a complete daily noise exposure history of the employee. The doseBusters methodology is the only approach that allows industry to differentiate between occupational and non-occupational hearing loss. More importantly, daily sampling provides continuous reinforcement to the employee, allowing him to adjust his habits to maintain daily exposures at a safe level. Employees are initially trained to wear the ESP when there are high noise levels, and to remove the ESP when noise levels are low. This approach maximizes the ability to communicate, therefore the doseBusters USA hearing conservation program impacts both health and safety issues. In addition, individual daily noise exposures vary widely from day-to-day. Workers are mobile and they perform varying tasks with varying pieces of equipment. It is well-documented that making personal noise dosimeter measurements once or only a few times per year on a small number of employees provides only a rough estimate of individual noise exposure. Will the doseBusters USA methodology revolutionize hearing conservation? Absolutely. It will become the new 'gold standard' in protecting employees against noise-induced hearing loss.
