Hearing Protection Buyer’s Guide

By CTD Blogger published on in Safety and Training

Every once in a while, you’ll come across someone claiming that they don’t “need” hearing protection. No matter their excuse, they are simply wrong. Gun fire produces noise levels that peak between 140db and 170 db. That noise is made even more damaging at indoor ranges as the ears are exposed to the same noise multiple times as it echoes off of the walls, floor and ceiling. The normal human threshold for pain is around 130db, and hearing loss can occur instantaneously at 120db. Even sounds as low as 78db can cause hearing loss over time.

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, earplugs 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 earplugs fully block the ear canal.

So much better and more comfortable than throwaway foam earplugs, the SureFire EP5 Sonic Defender earplugs will last over six months with the proper care.


There are quite a few different types of earplugs: single use, multiple-use, banded and corded. Single use earplugs are very inexpensive and disposable, and are probably the most commonly found earplugs. Almost everyone has come across these foam style plugs which are rolled and compressed before being inserted into the ear canal. Banded or corded earplugs 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.

Molded Earplugs

Molded earplugs are probably the best solution out there. In the past, they had to be custom made by a company and you had to wait for them to be made. In many cases that is still the case, and the best molded earplugs can run well over $100. They usually come with replaceable filters, and are very discreet and comfortable to wear. However, advancements in materials technology has led to the development of inexpensive do-it-yourself molded earplugs. These kits, such as the Radians custom molded earplugs are easy to make yourself at home in less than 30 minutes. They are washable, and made from non-toxic and hypo-allergenic silicone. They’re available in many colors, including tan for discreet use.


Pro Ears 300 Electronic Hearing Muffs

Even with a secondary form of hearing protection, electronic muffs will allow you to hear conversation and commands around you.

Earmuffs are found in two flavors: 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 along with a noise detection circuit that cuts out amplification when a loud noise occurs and blocks in instead. 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 over time, leading them to decrease the level of protection. Other earmuffs offer added features such as a jack to plug in your iPod.

Protect Your Hearing

It doesn’t matter whether you’re shooting indoors or out, whether you’re firing one shot while out hunting or a fusillade while you and your buddies plinking away at the range: you need to protect your hearing. The noise from a single gunshot can cause immediate hearing damage, so take reasonable precautions and protect your hearing.

    some useful information you have shared. thank you. do you have any recommendation for indoor shooting?


    • Dave Dolbee


      Always wear double hearing protection. Muffs alone can be easily displaced. As little as a single shot can do hearing damage. Plugs alone do not protect from the concussive forces of the muzzle blast from another firearm or your own when bouncing off the walls. ~Dave Dolbee

    NO, the higher the number the better! You want NRR numbers that are high, not low.

    does anyone know of the manufacturer of the PM4C10 ANSI S3.19
    ANC earmuffs? I would like to get in touch with them. About 4 years old, maybe not made anymore.

    My sister bought a pair of these molded ear plugs and said they worked really well. She was totally sick of my brother in law snoring all night and I think these might have saved them from divorce. She’d tried some other types but none of them worked.

    Hearing protectors only work if they fit your ears and you wear them properly. I always double up. Earplugs and muffs.

    I always double up. Earplugs and muffs. Sometimes when shouldering a rifle the muffs can get bumped and the seal is no longer good. Thus the use of the plugs.


  • Matthew


    It’s important to know most muffs will have a decibel rating and that the lower the number the better.
