Ear protection equipment is classified by its Noise Reduction Rating (NRR). NRR determines a device’s ability to decrease sound exposure. It concerns itself with decibels (dB). For instance, a product with a 30 NRR will reduce a 100-dB noise level to 70 dB. The higher the rating, the better the device will protect your hearing.

According to OSHA, hearing protection is required for any employee exposed to 85 decibels or higher over an 8-hour period or 100 decibels or greater over a 2-hour period.
Earplugs offer as much as 33 dB reduction. A maximum reduction for earmuffs is 31 dB. Combining both would give a 36 dB reduction.
Common dB levels of tools to keep in mind:
The goal is to reduce noise to the safe level of 70 dB at least. It's smart to invest in hearing protection even if you don't meet those levels. If your work exposes you to high levels of noise, have protection. The same goes for recreational activities, like sports or concerts.
There is no single best material for earplugs. Earplugs can be made from:
The best type of material for you can vary depending on their use.
Silicone earplugs and wax earplugs are used for ear protection from water. Swimmers, surfers and people who work around the water like silicone earplugs. They are waterproof and moldable to help create a better seal for the ear. For divers, it is important that the earplugs are vented. Vents keep the correct pressure balance between eardrums and the outer atmosphere.
Many musicians use silicone earplugs made for the industry. These are designed to dampen volume. But, they retain the ear’s perception of bass and treble levels. This allows music pros to protect their hearing but still analyze the music.
Foam earplugs are made from PVC or memory foam. Most of these are intended for disposable wear. The material allows it to be compacted to fit into the ear canal. Then, they expand to seal the ear against noise.
Metal earplugs are excellent for people who work in large venues. They work well for those exposed to subsonic sound for long periods. Metal earplugs have the density to block a wide range of sound frequencies. They have the advantage of being very easy to clean and sterilize. Opt for a foam-wrapped version of metal earplug. This makes them more comfortable.
Since earplugs fit right in the ear, they're better at noise reduction than earmuffs. This makes earplugs better in loud workspaces such as factories and airports. Their compact size makes them ideal for people who use them recreationally. Earplugs work more effectively in combination with other safety gear. They pair well with protective glasses and helmets. They do not interfere with other required headgear.
Disposable earplugs may not always fit correctly and comfortably. For this reason, reusable earplugs are made with more detail. For frequent users, they can be custom fit. This increases their cost, though.
Look for semi-insert earplugs if you find normal ones uncomfortable. Instead of rolling and compressing to fit inside ears, they use rigid headbands. The headbands have rubber or foam plugs on the end. The headband creates just enough pressure to clamp the plugs in place over the ears. They notably reduce the exposure to loud noises without inserting a plug deep inside the ear canal.
Earmuffs fit over the ear and are easy to adjust. They can always fit comfortably to the head of the wearer. They are great in colder climates since they help keep the ears warm. But they can be uncomfortable to wear for long periods during hot times. They typically have lower noise reduction ratings than earplugs.

Headphone earmuffs and electronic earmuffs serve dual purposes. They connect to music devices while filtering out unwanted background sounds. They also protect your hearing from subsonic noise.
Insert disposable earplugs properly. Roll the earplug between your fingers until the foam compresses into a thin tube. It takes about 30 seconds. Pull up on the top of ear to open the ear cavity. Insert the earplug. Allow the foam to expand in place to fit the ear, about 30 seconds.
Clean or discard earplugs daily. If clogged or dirty, earplugs can introduce bacteria. Dirty earplugs can lead to ear infections. Discard foam earplugs and use a fresh pair each day. Clean reusable earplugs daily. Use a peroxide, soap and water mixture and a small brush. Dry thoroughly before re-inserting in the ear.
Pay attention to earwax buildup. Daily earplug wear can cause wax to build up, which can in turn lead to ear problems. See a professional for any ear pain, sound distortion or ringing in ears. Pay attention to itching, unpleasant odor or discharge from your ears. A stuffed-up feeling can also indicate hearing impairment. Consult a hearing health professional, even if there is no pain. Hearing loss has been linked to other physical and emotional ailments. Chronic hearing loss can lead to depression, dementia and Alzheimer’s.
Passive hearing protection refers to devices that are designed to reduce the sound level that enters the ear, without the use of electronic components or power sources. Passive earmuffs are usually circumaural or over the ear protection. These earmuffs use cups that are filled with sound-absorbing material to reduce the sound level. When placed over the ear, the device creates a seal that prevents sound waves from entering the ear canal at full strength, reducing the overall sound level.
Passive hearing protection uses materials that absorb or attenuate sound waves to reduce the overall sound level, while electronic hearing protection uses built-in microphones and speakers to actively cancel out harmful sounds while allowing speech and other non-harmful sounds to be heard. Passive hearing protection is generally less expensive than electronic hearing protection, but does not offer the same level of situational awareness. Passive ear protection is a great option for hearing protection when communication is not desired. They can be used in many settings including mowing your lawn and at the range.
Choosing the right passive hearing protection involves considering factors such as the Noise Reduction Rating (NRR), comfort, and convenience and the type of activity you are participating in. The NRR is a measure of how much noise reduction a particular device can provide, and is listed on the packaging. The higher the number the more sound is blocked. Comfort is important, as the device should fit snugly but comfortably in the ear or over the ear. Convenience factors such as portability and ease of use should also be taken into consideration. Here are some tips on how to choose the right passive hearing protection for your needs:
By considering these factors, you can choose the right passive hearing protection to meet your specific needs and protect your hearing from loud noises during shooting and hunting activities.
It is very important to wear passive hearing protection when shooting or hunting, as the sound of a firearm can reach levels that are harmful to hearing. Even a single gunshot can produce enough noise to cause permanent hearing damage. Repeated exposure to loud sounds can lead to permanent hearing loss, so it’s important to protect your ears whenever possible.
Hearing loss can have a significant impact on your quality of life, making it difficult to communicate with others, enjoy music and other sounds, and even affect your ability to perform your job. The damage caused by exposure to loud noise is irreversible, so it’s important to take steps to protect your hearing.
Passive hearing protection can help to reduce the risk of hearing damage by reducing the level of noise that reaches the ears. It’s important to wear hearing protection consistently whenever you are exposed to loud noise from shooting or hunting activities. By doing so, you can enjoy your activities while also protecting your hearing for years to come.
Yes, passive hearing protection can be worn with other forms of protective equipment, such as eyewear and hats. In fact, it’s important to wear all forms of protective equipment together to ensure maximum protection from potential hazards.
When selecting passive hearing protection, it’s important to consider how it will work with other forms of protective equipment. For example, earmuffs may not fit well over certain types of eyewear or hats, so it may be necessary to choose a different type of passive hearing protection, such as earplugs. If you are wanting high levels of protection, wearing earplugs underneath over ear passive ear protection will give you an extra level of hearing protection. According to the US EPA this double protection increases attenuation by seven decibels.
It’s also important to ensure that all forms of protective equipment fit well and do not interfere with each other. Equipment that doesn’t fit properly or is uncomfortable to wear may be less effective at providing protection and may be more likely to be removed or adjusted during use, increasing the risk of injury.
Overall, wearing passive hearing protection in conjunction with other forms of protective equipment can help to ensure maximum protection during shooting and hunting activities.
