SAFETY MATTERS April 2017 airportbusiness 35 Once It's Gone, It's Gone: How to Protect Your Hearing on the Job Airside workers need to take proper hearing protection into consideration when on the jobs. That damage is irreparable. When it comes to hearing, once it's gone, it's gone. So how can we protect our hearing and preserve it, regardless of environmental noise? To best understand what damaging noise is, we need to talk about decibels (dB), or the way we measure sound intensity. On one end, 0 dB is barely audible sound. A normal conver- sation hovers around 55-65 dB. From there, we move into the higher — and more dangerous — ranges. Highway traffic typically measures at around 75 dB, while something as simple as a hairdryer accounts for 85 dB. A lawnmow- er garners 95 dB. Construction sites, as you can imagine, often creep up over 100dB on a regular basis. Jet engines — the most consis- tent source of environmental noise for airport workers — frequently register at 140 decibels. How loud is too loud? Anyone exposed to levels at or over 85 dB, particularly on a regu- lar basis or over a prolonged period of time, is at a high risk of hearing loss. Without proper hearing protection, running a chainsaw for just 15 minutes can cause permanent damage. Obviously, consistent exposure to the noise pro- duced by jet engines on a daily basis puts air- port workers in serious jeopardy of hearing loss. Considering over 10 million Americans suf- fer from noise-related permanent hearing loss, this is a problem that demands attention, not to mention more preventative measures. The FAA has been trying to improve noise control for decades, and continues to develop quieter aircraft and enhanced flight control measures. Someday, there may be jet engines that operate at the same decibel level as a car engine. Until then, however, airport employ- ees must take more immediate steps to protect themselves. Fortunately, the solution is not complicated. Hearing loss can be prevented by wearing good quality noise protection. If you are an airport worker exposed to hazardous levels of noise on the job, hearing loss is likely already happening. While you can't always control the noise, you can control how you protect yourself. Protective ear buds or ea r mu f f s t hat provide adequate Noi s e Re duc t ion Rating (NRR) can block out a signifi- cant percentage of damaging noise. W h e n s h o p - pi ng for hea r i ng protection, be sure to look for audiolo- gist-recommended products. The best hearing loss pre- vent ion produc t s will protect against hearing loss, tin- nitus, and the daily stress of excessive noise by dampening loud vibrations before they can damage your hearing. By blocking out such a large amount of environmental noise, using ear- buds or ear muffs allow you to keep music and conversations to safe, hearing-preserving level. We've all heard the old adage that an ounce of prevention is worth a pound of cure. One place where that is certainly the case is with hearing protection. Don't take your hearing for granted; keep it protected and safe for years to come. E xposure to environmental noise is one of the leading causes of hearing loss through- out the world, with approximately 30 mil- lion workers exposed to hazardous levels of noise on the job. Every day we are flooded with transport, industrial and recreation- al noises. This constant exposure wears down the delicate nerve hairs in the inner ear in the same way bristles on a toothbrush wear down over time.
