Some people do not accept particular kinds of protectors; every human being is different, and the anatomy of the ear and ear canal can vary significantly from person to person. It is a good idea for the employer to provide a number of different types of hearing protection from which workers can choose, keeping in mind any safety or hygienic reasons for not providing a particular kind of protector.
That is, a particular type of protector should not be used if noise levels are too high or if it proves to be inadequate from a hygienic point of view. For example, earplugs which are used in a plant setting where people reuse them throughout the day, often reinserting them with dirty fingers, can introduce dirt and bacteria into the ears, causing ear infections.
The bottom line on hearing protection is worker preference. If the workers do not like the type of protection for example, if it is uncomfortable, does not fit well, or is impractical , they will not wear it.
Follow manufacturer's instructions. With earplugs, for example, the ear should be pulled outward and upward with the opposite hand to enlarge and straighten the ear canal, and insert the plug with clean hands. In order to get full benefit, hearing protectors must be worn all the time during noisy work. If hearing protectors are removed only for a short duration, the protection is substantially reduced.

Comfortable enough to be worn. Most earplugs and earmuffs made for hunters have an NRR between 15 and 33 decibels. Some hunters even choose to double up by wearing earmuffs over a pair of earplugs. Please prove you are human by selecting the Car. Search for:. What is a safe sound level 85 dB is generally considered the threshold for safe listening exposure; anything louder can damage the tiny hair cells in the cochlea that are responsible for converting sounds into electrical impulses that are sent to the brain for interpretation.
Do you have a smallish head? Regular muffs may not fit well. Maybe a youth earmuff is appropriate. The cushions must enclose your ears and seal tight. We usually shoot two hours at our monthly events but with special shoots may be four to five hours.
There is also a difference in indoor range use vs outdoors. The indoor range is a sound box which will capture the sound and sustain it. Sound dissipates quickly in the outdoors so the NRR requirements may not be as high. Does this sound like buying holsters? N oise levels are measured in decibels, which we write "dB". A gun shot is rated at dB 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.
A product with a 28 to 31 NRR is 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.
There are quite a few different types of ear plugs: single use, multiple-use, banded and corded. Banded or corded ear plugs are best if you move between a noisy place and a non-noisy place, like between the shooting range and your range's lobby. Multiple-use earplugs are easier to use because they do not require rolling to fit in your ear. Earmuffs are either electronic or passive. Electronic earmuffs amplify quieter sounds, allowing you to hear your range master's commands.
These earmuffs will have integrated microphones and some have independent volume controls. Passive earmuffs simply block sound using foam and other materials located inside the ear cup. One thing to look for in your earmuffs is the style of band. Plastic headbands hold their shape better than a metal band. Metal bands can become stretched through time, leading them to decrease the level of protection.
Noise Reduction Rating NRR is the measurement, in decibels, of how well a hearing protector reduces noise as specified by the Environmental Protection Agency. The higher the NRR number the greater the noise reduction. While wearing hearing protection your exposure to noise is equal to the total noise level minus the NRR of the hearing protectors in use. For example, if you were exposed to 80db of noise but were wearing earplugs with an NRR of 29, your actual noise exposure would only be 51dB.
When dual protectors are used, the combined NRR provides approximately 5 - 10 decibels more than the higher rated of the two devices. The amount of on-the-job noise exposure can be determined through various testing devices. These models employ external microphones, internal speakers and a gain adjustment, allowing the user to hear surrounding sounds at normal or even louder-than-normal levels, which is extremely helpful for conducting conversation or receiving range commands. When a dangerously loud sound over 82dB is detected, the circuitry compresses the sound to the speakers inside the earcups until the noise returns to a safe level.
Because of their ability to amplify softer sounds while compressing dangerous ones, electronic earmuffs have become an attractive and popular option with shooters. They are also growing in popularity with hunters. Howard Leight offers several models of electronic earmuffs that offer 4x or even 5x amplification, while effectively compressing any continuous or impulse noises 82dB or higher.
We want to make sure our customers have everything they need to protect their hearing right out of the package. Too often, however, performance—the variable that matters most—is not given adequate consideration. There are also considerations to be made based on what and where someone is shooting. For example, certain firearms produce more sound than others. The shooting environment matters, too. Indoor shooting produces a lot of reverberation, and covered outdoor shooting can be just as bad.
Doubling up—the practice of wearing both foam earplugs along with earmuffs—is a viable option as well. You can expect to gain dB, which amounts to a significant increase in protection. Hearing protection is neither expensive, nor uncomfortable nor or inconvenient. Hearing aids, on the other hand, are, and can cost thousands of dollars.
