(PRWEB) December 14, 2010 — Many people, including those involved in shooting sports, take their hearing for granted. As a result they do not always pay close attention to wearing adequate hearing protection especially when they perceive noise levels to be relatively non-threatening. According to the NIDCD Information Clearinghouse when we are exposed to harmful noise sounds that are too loud or loud sounds that last a long time sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss (NIHL)This kind of hearing loss may be accompanied by tinnitus a ringing, buzzing, or roaring in the ears or head which may subside over time. Hearing loss and tinnitus may be experienced in one or both ears, and tinnitus may continue constantly or occasionally throughout a lifetime.To protect your hearingWear earplugs or other hearing protective devices when involved in a loud activity.

According to Amin Musani, Au.D., An avid target shooter can be exposed to an entire years worth of hazardous occupational noise in just a few minutesPeak sound levels from rifles and shot guns can range from 132 dB SPL (sound pressure level is another measurement) for small-caliber rifles to more than 172 dB SPL for high-powered firearmsA decibel is a unit of measurement measured on a logarithmic scale and there is a 10-fold increase in noise energy for each 10 dB increase. Said another way, an increase of 10 dB doubles the loudness levelSounds over 140 dB can cause pain, and prolonged exposure to noise over 85-90 dB can result in permanent hearing loss. Gunfire may be categorized as an impulse noise, which has the characteristic of an explosive burstnoise induced hearing loss (NIHL) and Acoustic Trauma are phenomenon that we most certainly do have control over and yet many shooters ignore the very basic principle of wearing hearing protection.

The sound signature from a gun shot can range from about 132 dB up to about 172 dB. Most of this range exceeds the 140 decibels often cited as the threshold for creating permanent hearing damage. An important piece of information to consider is that the decibel scale is exponential rather than arithmetic. For instance, an increase from 140 dB to 150 dB increases the sound pressure by 100%. Awareness of these facts make it imperative that adequate hearing protection be worn in any noise environment that exceeds recommended guidelines. Paying attention to using appropriate hearing protection at an early age will prevent unnecessary hearing loss and associated hearing problems that could result in a need for hearing aids and hearing enhancement devices as we age. Protecting hearing is not limited to shooting sports. Auto racing is another recreational activity that requires adequate protection. According to Diane Chun, When a Top Fuel dragster throttles up, a wave of sound strikes your chest like a fist. A nitro-powered dragster at full throttle puts out 120 decibels of soundexposure to noise at that level can damage your hearing. Perhaps permanently.

Fortunately, there are numerous choices to provide adequate hearing protection to both sports participants and observers. The HYSKORE
