Where To Buy Noise Cancelling Ear Muffs
Noise-Reduction Rating: Every pair of noise-reduction ear muffs is assigned an NRR (Noise-Reduction Rating), which approximates how much sound it can keep from reaching your ears. All of our recommendations have an NRR value of 23dB.

Some of our recommendations also have active noise cancellation, which use microphones to cancel out noises at certain frequencies. Active noise cancellation adds a significant amount of weight to the ear muffs, and requires them to be charged.
Despite only using passive noise cancellation, these noise reduction ear muffs reduce noise up to 125db. They lack some extras, but nail the core functionality necessary that helps keep your ears safe.
Although these headphones are powered, they only provide passive noise cancellation, and earn the same 23dB NRR rating as our other recommendations. Instead, 3M decided to build a pair of speakers and a Bluetooth chip into its ear muffs, turning them into a pair of wireless headphones.
The 3M Optime 98 is one of the most versatile earmuffs in industry today as it delivers the proper protection needed for a broad range of work areas with increased noise levels. When assessed noise levels reach up to 98 dBA, there is no better choice earmuff than the 3M Optime 98.
However, students, office workers, and people sensitive to noise are also increasingly using hearing protection earmuffs to reduce the noise and chatter around them so they can concentrate better and eliminate distractions.
When talking about noise reduction, noise cancelling, or noise blocking in this post, I am referring to passive noise reduction without using electronics to generate a counter signal to the noise signal.
Be aware though that you cannot just add the noise reduction of the earmuffs and earplugs. How much you can gain depends very much on the frequency. Still, in particular for the low and low-mid frequencies up to 1000 Hz, the gains you can achieve by wearing optimally inserted earplugs underneath your muffs can be substantial.
You can, however, eliminate the distracting nature of human speech by masking it with white noise. For this you could either wear earbuds underneath your earmuffs or use a flat speaker insert which I find more comfortable.
The X5A weigh 350 grams, which makes them heavier than all other muffs except for the 3M Pro-Grade (370 grams). I guess this is the price for their great noise isolation. Given the great headband, the weight is fine with me.
The Optime 105 are great NRR-30 noise reduction earmuffs. They are not quite as effective as the X5A, lagging behind slightly in the low-and-mid frequencies. Overall, the difference is not large, but it is clearly noticeable.
Like most earmuffs, the Leightning L3 use a single-shell cup design. The way they are designed, the great low-frequency noise attenuation is surprising. Howard Leight state that this is due to their patented air flow control technology.
As described in the post Creating Effective Speech Blockers for Office and Studying on a Shoestring, you can optionally combine them (as well as the other muffs in this review) with flat speakers and add a masking noise if you are as bothered by heated conversations as I am.
I tried the Mpow muffs with different distracting noise sources and also as a speech blocker (basically what you would get in an open office or café) and they perform well, but regardless of the noise I find them less effective than the Optime 105.
In this review, I have looked at seven different noise cancelling earmuffs and ranked my top 5. In my opinion all of the top 5 are good earmuffs. Each pair is optimal for a slightly different use case. Are you still wondering which ones to get?
Think how quiet submarines are. They have to be. This is life and death for submariners. The Kriegsmarine started covering the hulls of type 7s in rubber. This is now standard on all submarines. I recently modded my current sound reduction earmuffs by covering the external shell with rubber strips cut from a wheelbarrow tire. Then I used the remaining rubber scraps alternating with felt inside the shell. This greatly reduced low frequency noise.
I have tested a few noise protection earmuffs with built-in headphones.Please check out my review of the 3M Worktunes Connect for their noise reducing performance and sound quality.I like them, and in terms of their performance, they are a good alternative to the NRR-25 Optime 98.
Put in the earplugs and then play white noise through your earmuffs to mask the barking dogs.For your purpose, the combined noise reduction of well-inserted foam earplugs and the Worktunes Connect can get you close to what is possible.
Finally, as you have mentioned, your earmuffs claim (!) to reduce noise by 37 dB. In the introduction to this post, I have tried to shed some light on how numbers from different rating systems are often thrown around in marketing copy.
For low frequencies from 50 to 250 Hz, deeply inserted foam earplugs such as the 3M 1100 can outperform earmuffs.If you had them very deeply inserted you likely got better performance for noises such as traffic rumble and engine noise. If they are only half-inserted they lose that advantage.
Please note that earmuffs have to exert a higher headband force than headphones to provide their superior noise reduction.Most people get used to it and many workers use them for whole days, but this may bother some people.
If you are in the U.S., regardless of which earmuffs you are buying, make sure they have an EPA label with the NRR AND a table noise attenuation data by frequency (this is what the NRR is calculated from).
Dear Helmut,I cannot thank you enough for sharing your expertise on noise reduction. I am a college professor, I work a lot from home and I need quiet to read, think, and write. In my neighborhood, it seems that each homeowner has chosen to do their yardwork on a different day of the week. They spend a lot of time doing this and they use a lot of gas powered equipment, especially the infernal leafblower. I can hear this noise in my home and it makes me incredibly frustrated and angry. Noise cancelling headphones have proven worthless. As per your suggestion, I purchased the X5A Peltor earmuffs. Absolute silence. I am forever grateful.
In the not-too-distant past, people wore headphones solely for entertainment. Not anymore. Today headphones have become an all-day, everyday companion. People use noise cancelling headphones, in particular, for work as much as for play. We currently offer several styles of noise cancelling headphones, all of them featuring proprietary Bose noise cancelling technology that makes quiet sound quieter and music sound better.
Active noise reduction technology functions primarily by exploiting a principle of physics called phase cancellation. As you probably know, sound travels in waves, moving the air molecules. These waves travel through the air and into your ear canal, where they vibrate your eardrum. However, if a sound wave meets another sound wave that is the exact same in frequency and opposite in amplitude, the two largely negate each other.
If you are exposed to noise levels 100 dBA or greater (such as chainsaws or jackhammers) or if you are exposed to impulsive sounds (such as nail gun or weapons noise), you should wear double hearing protection (earmuffs over earplugs).
Consider also whether the noise at your job is continuous or if it stops and starts at various times during the day. Do you stay in the same place for most of the workday, or move from one area to another? Earmuffs are easier to remove and replace than earplugs, so they may be better for intermittent noise exposures. If earmuffs are not an option due to other issues (e.g., compatibility with other PPE), pre-formed earplugs may be easier to remove and replace than foam plugs. Level-dependent or sound restoration hearing protectors can also be useful for intermittent exposures; these types of hearing protection allow sound to pass through when the background noise levels are low and become protective when noise levels increase.
Do your hands frequently get dirty at work? If so, avoid using foam earplugs which must be rolled down with your fingers before insertion, unless hand-washing facilities are readily available and you have time to wash up each time you need to insert the earplugs. Do you work in a tight space? Earmuffs may not be compatible when working in a confined area. Is it very hot or very cold where you work? Earmuffs can be uncomfortable in hot environments; earmuff cushions can become ineffective in very cold environments.
Unfortunately, I needed hearing protection from car collisions occurring in a canyon on a roadway. I have a very good set of noise cancelling headset that is sufficient for my regular hearing protection needs. However, I do still suffer some pain and loss in the ear most affected by the car collision reververation sound. The other ear is minorly affected by the echo off the canyon wall. I did report this to an insurance agent.
That is a great question! In general, earmuffs are not recommended when you also have to wear eyeglasses or safety glasses. The temple piece creates a leak in the seal of the muff around the ear, which reduces the amount of sound reduction. For safety glasses, you can avoid the leakage problem by using safety glasses which attach around the head with Velcro straps (making sure the straps go over the muffs or under the headband to avoid the cushions surrounding the ear). For eyeglasses, if earplugs are not an option, choose a frame with the narrowest temple piece possible. Be aware that anything that disrupts the seal of the earmuff cushion will reduce the amount of noise reduction. If this cannot be avoided, you should be fit-tested to ensure you are getting enough sound attenuation despite the leak.
One company, Aegisound, makes actual noise cancelling hearing protection (custom ear plugs + earmuffs), but those protectors are usually used in extreme noise environments such as Naval Aircraft Carrier flight decks. These hearing protection devices are overkill for everyday hearing protection needs, and because of their specialized nature, they are cost prohibitive for most individuals. 041b061a72
