Passive Protection Buyer’s Guide

If you keep the before points in mind, you can easily go out to the market and buy passive protection, right? No!

NRR Ratings

All hearing protection gets a Noise Reduction Rating. The general consensus is that hearing protection for small caliber arms requires a NRR of 20.  Long guns and normal handguns should have a NRR of 25, while magnum arms and indoor shooting dictate a NRR of 2to 33.

Remember when shooting indoors, it is often best to double up on hearing protection, with plugs under muffs, especially when shooting the big guns.  And if you are worried about dead batteries, most electronic muffs strive for a battery life of around 500 hours.

Leight Impact Sport ear muffs.

Though they are only available in olive drab, of all the muffs I’ve tried, this one cannot be beat at its price range.  In fact, I would rather have these Howard Leights than some higher dollar muffs not mentioned here.

Pro ears.

The Slim Gold line is narrow enough not to clunk around on guns and is comfortable for all-day wear.  Like many other Pro Ears models, these come with the 3.5mm mini jack, allowing connectivity with outside devices like iPods, scanners and radios.  If style is an object, these bad boys are available in camo, white, pink, black, or green. They use either “N” or 12lithium batteries, and the auto shut off feature has definitely saved me some batteries.

Another option for those with an open budget and distaste for muffs is the Pro Ears Pro Fit custom inside-the-ear plugs. 

Cover those ears

Once hearing is lost, bid it adieu.  So if you have not already, get yourself some electronic muffs.  While I sure love a long day of banging away on the range, I still want to enjoy the sound of a whitetail crunching through the leaves behind my bow stand with my bare ears.  I’m willing to shell out a few dollars on electronic muffs today so that I don’t need some kind of hearing aids to enjoy that hunt tomorrow.

Basic headphones

The values are

Lower exposure action values (daily or weekly average noise exposure level at which the employer has to provide information and training and make hearing protection available.)

Upper exposure action values (daily or weekly average noise exposure above which the employer is required to take reasonably practicable measures to reduce noise exposure, such as engineering controls or other technical measures. The use of hearing protection is also mandatory if the noise cannot be controlled by these measures, or while these measures are being planned or carried out.) peak sound pressure of 13dB. peak sound pressure of 140 dB.

The HSE’s flow chart will also help you decide what you need to do:

L  = Low

The terms refer to the noise reduction of the chosen hearing protector at High, Medium and Low frequencies.

What are dBs (decibels)? dB (decibel) is used to measure the sound intensity. Because the human ear can register sounds across a huge range of intensities a linear scale is not suitable for measurement.

The dB scale is therefore a log scale which in very simple terms means the sound intensity roughly doubles for every dB increase. An increase of 20 dB would increase the sound intensity 100 times, (ie 60 dB is 100 times louder than 40 dB)

Selecting ear defenders for your workforce

Every person will have different requirements when it comes to ear defenders. It is essential to get the right fit, the right protection, and ensure the user understands how to use and maintain their ear defenders.

Selecting ear defenders for the particular noise hazard

Consider the frequency, pitch and intensity of the noise hazard. In industries such as mining workers can be exposed to very low frequencies.

Selecting ear defenders for your industry

Music, construction and airport workers are exposed to different noise and therefore have very different requirements. There are many ear defenders and headphones specially designed for musicians so that the full range of frequencies can be heard and there are specialist hearing protectors for use during firearms practice. Some ear defenders will only be suitable for indoor or outdoor use – so check before you buy.

Selecting ear defenders based on your risk assessment

Your risk assessment should look at the task, the user, the environment, the exposure action values and limit values. The assessment should also identify what you need to do to comply with the law and identify any employees who need to be provided with health surveillance.

Making sure you meet ratings, requirements, standards, certification and legislation

As with any personal protective equipment that you procure, ear defenders should meet the requirements of international standards and relevant legislation. CE markings, EN, ISO and BS codes show which equipment meets standards for safety, design and performance. See the legislation and standards section of this guide to understand more about the exact standards and markings you should be looking for.

Also consider decibels, Single Noise Ratings and frequencies as detailed above.

Remember some headphones will not meet the criteria of ear protection.

Faro G2

Digital (Dynamic) Noise Reduction (DNR). A new technology, DNR is a different way of analyzing and attenuating unwanted noise. DNR uses digital electronic techniques to remove the noise components from the incoming signal using mathematical formulas and digitization of the incoming signal.

Touch controls

The Sony WH-1000XMare an excellent revision of an already great pair of headphones: They sound great, deftly wield noise cancellation technology and cost just as much as a pair of Bose QC35s. They might have a slightly shorter battery life than Bose’s flagship over-ear headphones, but Sony’s WH-1000XMoutclass the QC3in terms of performance and feature-set.  

You’d want to pick these Sony headphones over the Bose because not only do they provide the same level of awesome noise-cancellation, but they have three neat tricks that Bose just doesn’t have on its headphones: One is an ambient noise mode that only lets in mid-to-high frequency tones (announcements over a loudspeaker, for instance) and another being Quick Attention mode that allows you to let in all outside noise without taking off the headphones. (The latter is perfect when giving a drink order on a plane or speaking to a coworker for a brief moment before diving back into your work.) The last trick Sony has up its sleeve is the LDAC codec. Alongside the widely adopted aptX HD standard, LDAC enables Hi-Res Audio playback using the 1000XM2.

Great-sounding, feature-packed and just as affordable as the competition? The Sony WH-1000XMare our all-around pick for best noise-cancelling cans.

Still wired

You get a lot for the money here. In the box comes the headphones, a hard case for storage and the headphones rock a rechargeable battery that provides noise cancellation for close to 30 hours. But best of all, the sound performance is extremely well balanced and warm.

Wired headphones

A few years ago, the Bose QuietComfort 2are the best noise-cancelling headphones we’ve ever used. The lows, mids and highs came through clear as day, never stepping over each other. Music of all sorts sounded predictably incredible. With the noise-cancellation turned on, we never felt further immersed and concentrated than when we let the QC2engulf our ears.

But that was a few years ago and time has moved on since. Bose has released not just one sequel to these headphones, but two: the QC3and QC3II with Google Assistant built in, both of which we’d recommend above the QC25.

But, it’s not all bad. If you don’t mind using the older, wired headphones, the QC25s are a finely-tuned set of cans that provide over 3hours of very good noise-cancelling performance with one AAA battery. 

Sound lacks definition

Bowers and Wilkins are a little late to the noise-cancellation game, but their first foray impresses. 

The PX Wireless aren’t just a great sounding pair of headphones, they’ve also got a number of other interesting tricks up their sleeve. They’ll turn on and off automatically depending on whether you’re wearing them or not, and they also feature the future-proof USB-C charging standard. 

In our opinion their only downside is the sound quality, which we felt lacks the depth of the flagship headphones from Bose and Sony. 

That said, if you’ve been a fan of the look of B&W’s headphones in the past then the PX Wireless are certainly worth a listen. 

Headband lacks padding

With noise-cancelling tech just as effective as that in headphones from rival Bose, and with a more musical sonic ability, the Sennheiser HD 4.50 BTNC are a definite contender for the noise-cancelling crown. More affordable and easy to travel with, these lightweight headphones are a great value all-rounder, whether for flights, commuter trains or busy offices. 

Design-wise, the Sennheiser HD 4.50 BTNCs seem a more slimmed-down, lighter and more focused effort than the bulky and expensive alternatives from Bose and Sony; and crucially, the HD 4.50 BTNCs are just as good with audio, and almost as good on noise-canceling. Whether you’re after noise canceling for long-haul ravel, for the commute, or just to stay more productive in a noisy office, the Sennheiser HD 4.50 BTNCs are worth considering. 

Short-range wireless

The Samsung Level On Pro Wireless are one of the few headphones we’ve tested that feel like they’re meant as a package deal for another device. Yes they’ll work with every Bluetooth and 3.5mm jack-equipped handset on the market, but you’re better off sticking to a Samsung device in order to squeeze every ounce of aural goodness from the Ultra High Quality (UHQ) audio codec.

It’s one of the comfiest pair of cans on the market, and they’re also much cheaper than a lot of the competition. If it had a better sound quality for the vast majority of cell phone users it would be an easy recommendation but, as it stands, really makes the most sense at checkout when purchased alongside Samsung’s Next Big Thing.

Passive Protection

With no moving parts, passive protection is the most basic and inexpensive pro there is, as well as a necessity to any trad rack. Passive pro typically refers to “nuts,” “chocks,” “stoppers,” “RPs” or “wires”—different names to describe essentially the same thing. Nuts come in various shapes and sizes, and even in different types of metal. But the inherent design is a chunk of metal that has a cable drilled or machined into it; the chunk of metal wedges into cracks/constrictions in the rock, while the cable is used for clipping.

Micro Cams

A “three-cam unit” is a special cam that has only three cams at the head. They are excellent for smaller cracks and tiny fissures on the rock. Their narrower profile allows them to fit in shallower cracks, such as certain pin scars and pockets.

Quickdraws & Alpine Draws

Quickdraws and Alpine Draws are both used in trad climbing to attach your pieces of protection to the rope. Quickdraws have fixed lengths and are commonly used in sport climbing but can be useful on trad routes, especially those with straight, vertical cracks that create a more or less straight rope path between the leader and belayer.

This is a loop of nylon or Dyneema, often sewn with a bar-tack, and it serves a variety of purposes


Similar to slings in construction, runners typically have a much larger circumference than most slings. Use them to create anchors or extend placements on traversing terrain, or sling them around rocks to protect you in places where neither passive nor active placements can.


Made from a loop of 6mm or 7mm cord, cordelettes are inexpensive pieces of gear that are very versatile. Use them for anchors, backups, or leave them behind when you need to lower for an emergency. You can always buy another one because they are so inexpensive.

The “Single Rack”

Below are my recommendations for building a basic single rack that will get you up and down most climbs at most climbing areas, especially when you combine racks with your partner—which is standard.

24-inch “shoulder-length” slings (nylon or Dyneema). These are generally used to extend placements and make alpine draws.

The mission of Cheaper Than Dirt!’s blog, “The Shooter’s Log,” is to provide information-not opinions-to our customers and the shooting community. We want you, our readers, to be able to make informed decisions. The information provided here does not represent the views of Cheaper Than Dirt!


The National Institute on Deafness and Other Communication Disorders (NIDCD) estimates that approximately 15% of Americans between the ages of 20 and 6(or 2million Americans) have hearing loss that may have been caused by exposure to noise at work or in leisure activities.

Tips for Selecting the Best Ear Protection For Shooting


Most shooters simply use ear plugs when shooting. They’re incredibly cheap, disposable, easy to put in and take out, fit easily in a pocket or bag, and they’re commonly seen as the most comfortable option. Earplugs also don’t interfere with prescription and safety glasses. However, some folks don’t think they are the best ear protection for shooting as they can easily fall out, may not fit properly to begin with and allow more noise to come through.​

However as technology has progressed, earplugs are no longer just pieces of foam that you plug into your ear. High-end earplugs are made from modern materials like medical-grade polymer that is soft, durable, and long-lasting. If you are not a regular or serious shooter, the earplugs will be the best hearing protection for shooting as they are inexpensive and easy to use. Hunters will likely prefer earplugs to earmuffs as they are more convenient to wear out on the hunting grounds, while still providing some protection.

Passive Ear Muffs

Passive ear muffs provide shooters with comfortable ear protection that provide excellent comfort as they have soft padding that fits over the ear. They also provide better protection from higher decibel levels than ear plugs do, but are of course generally more expensive than earplugs.​

If you are a regular shooter that wants better protection than what earplugs can provide, but do not necessarily want to invest in expensive electronic earmuffs, then passive earmuffs will the best hearing protection for shooting.

Electronic Ear Muffs

This allows you to able to hear regularly while you use them. You can hear warnings, conversation and more very clearly, When a noise above a certain decibel level is detected, the earmuffs will automatically reduce the noise.

They typically provide the best protection from loud noises, have volume adjustment, and some can be used as regular headphones with an audio jack. In the event that the batteries run dry, they can also function as regular passive ear muffs.

The one main drawback to electronic ear muffs is the high price. However, those who shoot on a very regular basis may find the investment well worth the money.


On average, suppressors reduce the noise of a gunshot by 20 to 3decibels (dB). The Hearing Protection Act (HPA) was introduced to remove suppressors from the purview of the National Firearms Act (If you want to read more about what the HPA entails, you can have a look at ASA article about it here). The HPA will make it easier for hunters and sportsmen to protect their hearing in the 4states where private suppressor ownership is currently legal, and the 3states where hunting with a suppressor is legal.​

The great benefit of using a suppressor is that not only does it protect your hearing, but it also reduces the noise that the folks around you are being exposed to when you fire your gun. So if you have some neighbours, they will probably tell you that a suppressor is the best hearing protection for shooting 🙂

Tips for Selecting the Best Ear Protection For Shooting

Now that you know of the benefits and drawbacks of each type of ear protection, you should follow these key factors when selecting the best ear protection for shooting in terms of your own practices and preferences.

Noise Reduction Rating

The most important aspect to look for when searching for the best ear protection for shooting is a good noise reduction rating or NRR. The NRR is the official rating system for ear protection with ratings ranging from 0 to 3decibels. The rating system may seem a little confusing, but it’s actually quite simple.

The NRR rating in decibels is the amount of decibels that is canceled out by the item. You merely subtract the rating from the decibel level of the firearm. For example, a.4Colt produces around 15decibels of noise. If you had ear protection with a rating of 30, you would actually only be exposed to 12decibels of sound.

Prolonged exposure to these levels may still cause some damage, but one exposure to the noise levels without ear protection can immediately cause permanent damage. The higher the rating, the better.

Is the best hearing protection for shooting also the most expensive option? If you don’t shoot very regularly, ear plugs can be a great option as they’re quite cheap. You can get a pack of ear plugs for a couple of Dollars.

Very serious shooters may benefit most from investing in electronic ear muffs as they provide many benefits that would be great for sport shooters and avid hunters. These can be a great option to anyone if you can afford it, but they’d be most useful for people who shoot on a very regular basis.


Ear protection is typically worn for fairly long periods of time. The best ear protection for shooting should be very comfortable to ensure that they won’t become irritating or even painful over time.

Choose very soft and moldable ear plugs, ensure that ear muffs have sufficient padding, and choose ear muffs that fit well and can be adjusted easily.

Choosing a color for your ear protection is more than just personal preference. Camouflage can be beneficial in keeping hunters hidden from prey while bright colors can allow other shooters to spot you from far away, creating a safer shooting environment.

Finding a color that creates additional benefits to your hunting or shooting is vital in finding the best ear protection for shooting.

Howard Leight Leightning L0F Super Slimline Earmuff

If you do not like the bulkiness of the 3M Peltor earmuffs, then these super slim earmuffs from Howard Leight might just be the best ear protection for shooting for you. They weigh considerably less than the 3M Peltor earmuffs and have an overall slim design. Of course the cost of that is that they have a lower NRR than the 3M Peltor, with an NRR of 2dB.

Similar to the 3M Peltor earmuffs, these earmuffs from Howard Leight offer excellent comfort so you can wear them for extended periods of time.

Electronic Earmuffs

If you are a serious shooter and want the best ear protection for shooting out there, then you need to invest in a solid pair of electronic earmuffs. They definitely cost more than earplugs and passive earmuffs, but offer so much more in the form of the noise management technology that comes with it.

Howard Leight Impact Sport OD Electric Earmuff

If you are a hunter that need to be able to hear your game, or a shooter at the range that need to be able to hear the range safety officer, and are serious about protecting your hearing then these are the earmuffs that will probably be the best ear protection for shooting for you.

Why do we say that? It has a NRR of 2dB and provides x amplification, which means it protects you against noises above 8dB while amplifying lower noise levels (such as the sounds from game or the voice of a person trying to talk to you). Combine this with its sleek design, these earmuffs are perfect to use with rifle stocks when out hunting.

It also comes with an auxiliary jack so that you can plug it into a MPplayer if you want to. If we were buying electronic earmuffs, these are what we would buy.

What Do You Think – What Is The Best Ear Protection for Shooting?

There will be different opinions on what the best ear protection for shooting is, however from the research conducted by leading medical institutions it is clear that when you go shooting, even for just a little bit, you need to consider what the best hearing protection for you will be.

Shoe Last

The last refers to a unique foot-shaped model which is used to build the shoe. It is often designed to give the shoes a unique height and instep volume. Most rock climbing shoes come with slip lasted features, which are perfect for your needs.

Last construction

The last also plays an essential role in the shape of the shoe. The three main ones include

Straight- these shoes are developed around a straight last, which are sometimes designed to provide a relaxed fit for optimal comfort. They are often perfect for long days of climbing and with powerful features to match

Power amp specifications to consider

In evaluating power amps, specifications can help you narrow down your selection. But as we note below, manufacturers calculate those specs in different ways. Understanding what the numbers mean and how they’re calculated will help you shop smart.

Amplifier modes

Browsing through different power amp models, you will see that many amps have per-channel power ratings. The channels on these amplifiers can be operated in a number of different configurations, depending on your needs.

Amplifier specs usually indicate output running in both stereo and bridged modes. When running an amp in bridged mode, be sure to observe any warnings in the manufacturer’s manual to avoid damaging your gear.

Built-in DSP

DSP, or digital signal processing, is available on some power amps. It converts the input analog signal to a digital bitstream, allowing you to control and shape the signal in several ways. Some DSP processing you’ll find on amps includes:

Limiting – A means to control the peaks of strong input signals, usually to prevent overloading the amp or damaging the speakers.

Filtering – Some power amps offer filtering features such as low-, high-, or band-pass filters to emphasize certain frequencies and/or prevent damage caused by very low-frequency signals.

Compression – A method of limiting the dynamic range of an audio signal, for audio enhancement or to avoid distortion.

Note that these signal processing tasks can also be handled by specialized standalone units, and many professional audio engineers prefer using them.


In live music performance, levels vary constantly. Momentary musical peaks can put a lot of demand on your PA. Be sure your amplifier and speakers can handle these momentary peaks without distorting. To do this, the amp needs enough reserve power or “headroom” as audio engineers refer to it. We’ll discuss this in a little more depth next.

Matching your amp and speakers

Matching power between your amp and speakers can be a little baffling. Don Boomer of Peavey offers some general guidelines in his excellent article on the subject. For the best performance, he advises that your speakers’ “program” watts rating be the same as the amp’s RMS/continuous output wattage rating. But he hastens to add that does not grant you license to mic a kick drum without limiting its huge low-frequency output.

As Boomer explains, clipping—the flattening of waveforms that produces ugly-sounding distortion—is what really destroys speakers. A high pass filter in your signal chain is essential to protect your amp and speakers from meltdowns caused by their attempts to reproduce bass and drum frequencies beyond their intended range. Keep an eye on your amp’s clipping indicators and believe them. If you’re seeing a flickering red light on anything other than the kick drum beat, it’s likely your speakers are being pushed beyond their limits.

The impedance factor

Ohms measure the electrical resistance of a circuit, and PA amps are typically designed to operate with speakers having 4, 8, or 16-ohm ratings. You’ll usually get the best performance and minimize risk of gear damage by exactly matching your amp’s’ impedance with the speaker load you connect it to.

If the the total impedance of your speakers is too high for the amp, the power delivered to them will be insufficient. If the speaker load is too low on the other hand, the amp may overload your speakers damaging them and itself in the process.

How speakers are connected to the amp effects their impedance. There are basically two ways of connecting speakers to your amp:

Parallel: Each speaker cabinet is independently connected to the amp via its own circuit. This is is the simplest and safest kind of connection, especially if your speakers vary in their impedance ratings.

Series: Multiple speaker cabinets share the same connection from the amp. (Think Christmas tree lights.)

Without getting into the theory, it’s generally best to choose speaker cabinets that have the same impedance rating and to connect them in parallel to your amplifier.

How to choose shooting ear protection

All gunshots exceed the normal level for hearing, so it becomes imperative for you to use hearing protection when you shoot. In fact, you should consider doing this as primary gun safety. There are several options for hearing protection, each depending on your preference and budget. Here they are:

Ear plugs: Ear plugs are made of soft and compact foam. They are also comparatively inexpensive and can fade noise and so protect your hearing. They are also available in disposable form, and are easily available. However, the downsides are that you might be uncomfortable wearing something in your ears.

Ear muffs: There are two kinds of ear muffs that help bring about noise reduction while hunting or indulging in sports shooting. They are:

Electronic ear muffs: These muffs are made with modern space-age technology to block out sound selectively. Basically, they are passive ear muffs with holes that make room for an electronics package to send in muffled sounds while shutting out louder ones. The advantage here is that you can hear the noise and conversation around you but at a reduced noise level and you get the best hearing protection.

Product Brand

Now that you know the kind of hearing devices that are available, you should check them out online before buying. Read up as much as you can about them and then make an informed decision. You can also read user reviews so that you also know their drawbacks.

New Tech for an Old Problem

The challenge, then, is to select a product that can fend off known threats as well as detect odd behavior that hasn’t been seen before. To help, quite a few endpoint protection products have introduced a form of machine learning (ML) to their anti-malware engines. A sizeable portion of them are also able to detect the style of threats that would be seen during a direct cyber-attack, which can more quickly point to a source and a solution.

As a bonus, this same tech can sometimes pick up script-based attacks that have, in the past, gone mostly undetected. This will hopefully put a dent in the successful deployments of ransomware and other data-gathering attacks. As malware and ransomware writers are veering more toward this style of engagement, it’s become a major factor in what will truly add security to a small business. Unfortunately, malware scanners aren’t always sensitive enough to pick up these threats by using just their default settings and increasing the aggressiveness sometimes has a performance impact on users. Finding the right balance can often be a challenge and may result in some dissatisfied users in the short term. But you need to weigh that carefully against the cost of compromised systems and data.

At the end of the day, it becomes a question of, “What’s good enough?” The answer will vary from customer to customer depending on specific needs, custom processes, and risk factors. However, one thing is clear: The internet is an ocean of dangerous waters and those waters are only getting deeper. Having an adequate defense isn’t just important, it’s critical.
