Hearing loss is not fun and can be prevented.ĭownload Gunfire Noise Level Flyer–PDF (154k). LAWSUITS HAVE ALREADY BEEN RECOGNIZED FOR GUNFIRE NOISE THAT HAS RESULTED IN HEARING LOSS.ĪLWAYS CONSULT A PROFESSIONAL AUDIOLOGIST, OTOLOGIST, OR OTOLARYNGOLOGIST WITH YOUR HEARING PROBLEMS. BE SURE TO USE ADEQUATE EAR PROTECTION WHEN USING A FIREARM AND BE CAREFUL OF THOSE NEARBY. IF YOU INCORPORATE A PROCEDURE INTO YOUR SHOOTING THAT INCREASES THE SOUND LEVEL, YOU ALSO INCREASE THE RISK OF HEARING LOSS TO YOURSELF AND POSSIBLY THOSE WHO STAND NEAR YOU. AS THE SOUND PRESSURES INCREASE, SO DOES THE RISK OF PERMANENT HEARING LOSS. OUR WARNING IS SIMPLE AND IS IN THE BEST INTERESTS OF EACH SHOOTER. Imagine what the noise levels must be when we incorporate muzzle brakes or porting into firearms, or have a gun explode near the ear due to malfunction. No wonder we hear numerous reports about hearing loss as a result of firearms including acoustic traumas that take hearing completely as a result of one shot. The above averages are for all types of ammunition used in these firearms, and should be considered fairly representative. It should be noticed that this figure of 164.5 dB approaches the practical limit of impulse noise measurement capability inherent in most modern sound level meters. No vídeo de hoje vou apresentar um teste não-científico que fiz comparando a perfuração entre duas munições: 9mm ETOG 124gr CBC vs. There was also a greater range, from 152.4dB to 164.5dB, representing 12 dB difference, or more than 10 time as much acoustic energy for the top end of the pistol spectrum. Krammer adds that sound pressure levels for the various pistols and ammunition tested yielded an average mean of 157.5 dB, which is greater than those previously shown for shotgun and rifle noise levels. This is approximately 14dB beyond the threshold of pain, and more than sufficient to cause acoustic trauma. Krammer continues to say that shotgun noise averaged slightly more that 150dB. Table-1-SHOTGUN-NOISE-DATA-DECIBEL-AVERAGES. Krammer, Ph.D., Ball State University, Muncie, Indiana has documented the following pressure levels. 357 magnum pistol, which can expose a shooter to 165 dB for 2msec, is equivalent to over 40 hours in a noisy workplace.ĭr. Louis, the damage caused by one shot from a. senior research scientist in charge of the NOISE LABORATORY at the Central Institute for the Deaf in St. Keep in mind that conversational speech is approximately 60-65 dB, and the threshold of pain is considered to be 140 dB.Īccording to Dr. Use this chart as a reference guide for promoting the need of using adequate hearing protection. With the introduction of MUZZLE BRAKES and PORTING, the risks of hearing loss dramatically increase. Using Earphones For Hearing Protection? Read ThisĬlick to View Products that Protect Hearing for Hunting and Shootingīelow we have listed critical data describing peak sound pressure levels produced by firearms used in shooting and hunting sports.Ī serious byproduct of this exposure is sensory-neural hearing loss, which cannot be restored to normal. As this article says, there are reasons for any of the three, depending on what you are doing.In-ear devices like AirPods and headphones aren’t meant to protect your hearingĪn Urgent Word of Caution Regarding Use of Earphones for Hearing Protection While Shooting I’d rather shoot a 45 (ACP or Colt) than a 40, or 10mm or anything with “magnum” in the listing - it’s not a snap recoil, it’s more of a push – I can shoot a hundred rounds with no issues – but it’s a large frame, and has that single-stack capacity issue - but if I were in the country, I would be carrying the 45, with hollowpoints. I have a Springfield 45, and I’ve never understood the “oh, the recoil!” angst. easier for concealed carry, but snappy recoil, which makes for less accuracy - I use it for carry, because if I shoot someone more than fifteen feet away, I’ll be going to jail, and less than fifteen feet, my three shot groups are about 6″. A classic review and debate of the 4 most popular self defense calibers. My first pistol was a CZ75 9mm – bought it for two reasons it was half the price of the Beretta, and the salesperson said, “You can throw it on the ground, run over it with a truck, pick it up, and it will still shoot.” I still have it, and I’ve put about 3,000 rounds through it, and it fits me really well.
