What's that ringing in my ears?

 
Without ringing in your ears! by shooting at Frontier Firearms.

Over time sounds as low as 78db can cause permanent hearing loss. 

The normal human threshold for pain is around 130db, and hearing loss can occur instantaneously at 120db.

Gun fire produces noise levels that peak between 140db and 170 db. 

Additionally the noise from gun fire is made even more damaging at old, obsolete indoor ranges built before modern safety standards without the use of modern sound attenuation technology.

Hearing loss starts at 78db. Gun Fire =>170db
In old ranges the ears are exposed to the same noise multiple times as the gun shots echoes off of walls, floor, ceiling and the steel plates of the backstops as the bullets smash into them!

However, the owners of Frontier Firearms understand the danger posed to shooters' hearing.  


That's why Frontier Firearms spent over $25,000 installing sound absorbing/dampening technology.  

That's why each of our shooting lanes - walls and ceiling is equipped with specially designed, fire-resistant acoustical foam and sound attenuating ballistic rubber tiles.

Sure we could have saved money and not installed these important safety measures.  But unlike other range operators, we felt our shooter's hearing to be as precious as our own. So we spent the extra money to prevent the sound of gun fire from echoing over and over.

NRR 33 FREE!
In addition, Frontier offers each shooter the FREE use of a set of Pro Ears Ultra™ NRR 33 Ear Muffs.  The Pro Ears Ultra aren't cheap - they're the best money can buy -  but like your hearing they're worth it because they offer the best protection and highest NRR* rating (33) available in passive headsets.  
(How many other ranges offer you $40 headsets to use FREE?)

The bottom line is that your hearing is not only important to your but it is important to us.  

So much so we spent $25,000 up front to protect it and we continue to offer the best hearing protection available FREE of charge.



This year prevent that ringing in your ears - its a sign of serious nerve damage and permanent hearing loss, by shooting in the areas only indoor range designed to modern safety standards!

Noise levels are measured in decibels, which we write “dB”. A gun shot is rated at 149dB and, to compare, the typical office generally has a noise level of 60dB to 65dB. Noises louder than 80 decibels are dangerous and can cause immediate and permanent hearing loss. When we look at what hearing protection to buy, we need to pay close attention to the product’s NRR, or Noise Reduction Rating, which is defined as the maximum number of decibels (dB) that the hearing protector will reduce the sound level when worn. By law, all hearing protection products have to have a NRR rating. The highest NRR rating you can get is 33 NRR. Products with a 28 to 31 NRR are recommended for indoor shooting. There are two different kinds of hearing protection, ear plugs and ear muffs. The National Institute for Occupational Safety and Health actually recommends using both earplugs and earmuffs together when shooting. It might come as a surprise to hear that earplugs can actually offer more protection than ear muffs, because ear plugs fully block the ear canal.

The NRR is a single number rating which is required by law to be shown on the label of each hearing protector sold in the United States. The NRR is specified by 40 CFR code of Federal Regulations, Part 211, Product Noise Labeling, Subpart B - Hearing Protection Devises. It (the NRR) is independent of the noise spectrum in which it is applied.
The values of sound attenuation used for calculation of the NRR are determined in accordance with ANSI S3.19-1974, "American National Standard for the Measurement of Real-Ear Hearing Protector Attenuation and Physical Attenuation of Earmuffs." The NRR calculation assumes a pink noise with octave-band levels of 100dB. Thereafter various correction factors for C-weighting scale and A-weighting scale are introduced. The octave-band noise levels are logarithmically summed to obtain the overall sound level in dB(C) and dB(A). The NRR is computed by subtracting 3 dB from the difference between the unprotected C-weighted and the protected A-weighted levels at the ear.
