LAWSUITS HAVE ALREADY BEEN RECOGNIZED FOR GUNFIRE NOISE THAT HAS RESULTED IN HEARING LOSS.ДЄLWAYS 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. To put this in better perspective, a Daisy Red Ryder BB gun is in the high 90s, and high powered. A good silencer can lower that to 130 or even 118 decibels, still a lot louder than the new Quiet-.22 we have here. AS THE SOUND PRESSURES INCREASE, SO DOES THE RISK OF PERMANENT HEARING LOSS. 22LR out of a 3ВЅ barrel registers 160.7 decibels. 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. 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.Дr. 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.ДЄccording 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.
