Gunshots are some of the loudest noises by human activity. They can be loud to a level of 140 dBA compared to a chainsaw’s 109 dBA. A .32 Long fires a 152.4 decibel (dB) blast while a .44 S&W Magnum blast fires at 164.5 dB. A single gunshot can result in a Temporary Threshold Shift which is a temporarily reduced ability to hear the full range of sounds. A Swedish study on shooters showed that prolonged working with guns can lead to High-Frequency Hearing Impairment (HFHI) which is permanent hearing loss. Sustained sounds above this level can lead to gradual and permanent hearing loss called the shooter's ear. Wearing shooting earmuffs is highly advised for both casual shooters and security professionals.
Shooting Ear Muffs
Ear muffs for hearing protection are an affordable yet effective solution for shooting. They are available in a number of styles including Standard Headband, Folding Headband, Cap-Attach and Neckband Ear Muffs.
What is the best shooting ear muff?
The best ear muffs for shooting should have a noise reduction rating (NRR) of over 21. Calculating the sound level you are exposed to is easy. You take the ear muff’s NRR, subtract it and then divide by 2. The number you get is what you subtract from the decibel level you are exposed to. For ear muffs with an NRR of 30, (31-7)/2= 12. If you are exposed to a gunshot of the decibel level of 145 dB, you are protected 145-12 which is 133 dB. This means you should go for shooting ear muffs with the highest NRR number.
How long does ear ringing last after shooting guns?
Tinnitus is a condition in which the ears keep ringing after being exposed to loud sounds. Gun shooters report tinnitus for up to 16 hours after shooting guns. Earjobs offers a collection of shooter's ear muffs and ear plugs that can protect your ears very effectively while shooting. Keep your ears protected at the range with electronic shooting ear muffs and keep shooting for longer.
