Hearing Protection

Hearing Protection PPE Explored

If you're working in a noisy environment, you've probably been told you need to wear hearing protection.

But what does that actually mean? Is it just a case of popping in some earplugs and hoping for the best, or is there more to it?

Well, actually, there is a lot more to it than just that, and getting it right is really important for you and your workforce's long-term health.

As a result, we have put together this handy guide on hearing protection to help you understand more about your options and some areas you need to focus on in regard to this that you may not be aware of.

So let’s make your workplace safer, comfier, and more protected — because a healthy body is the best tool you’ve got.

Then, if you are still not sure, our helpful customer service team is on hand to answer any questions you may have.

What Are Hearing Protection Products?

Definition: Hearing protection products are items of Personal Protective Equipment (PPE) are designed to prevent Noise-induced Hearing Loss (NIHL) by reducing the level of sound reaching the eardrum.

Known as 'Attenuation', this reduction is achieved in two primary ways: earplugs that occlude the ear canal or earmuffs (ear defenders) that create an acoustic seal over the outer ear.

The performance of these hearing protection devices is then quantified by a standardised rating, such as the Single Number Rating (SNR) in Europe - which indicates the average decibel (dB) reduction provided by the item, which ensures that the noise exposure is kept below legally mandated action levels.

But First, Why Even Bother with Hearing Protection, Why Does It Matter?

Sometimes, just wearing hearing protection can feel uncomfortable or unnatural if you are not used to wearing them, and you might feel a bit cut off from what's going on around you as well.

But the alternative is much, much worse.

For instance, constant exposure to loud noise can lead to permanent hearing damage, something as covered above, called Noise-Induced Hearing Loss (NIHL).

It is also not just about everything sounding a bit quieter either, as it can also cause Tinnitus, which is a constant ringing, buzzing or humming in your ears.

Now, if you can imagine that never goes away, it really makes it worth a bit of discomfort now to avoid that later on from occurring.

The Health and Safety Executive (HSE) here in the UK also reports that an estimated 17,000 people in the UK suffer from deafness, Tinnitus, or other ear conditions as a result of exposure to excessive noise at work. [Cite]

Even taking that into consideration, there are also a lot of legal requirements that you need to follow in this area as well.

The Law and Your Ears, What You Need to Know

Here in the UK, we have the Control of Noise at Work Regulations 2005.

It might sound a bit formal, but it's all about keeping you and your workforce safe at the end of the day.

Now, some of the key areas of the CNWR2025 are:

The Lower Action Level (80 decibels)

If you or your workforce are exposed to a daily or weekly average noise level of 80dB, your employer has to assess the risks and give information and training around this.

As an employer, you also have to provide hearing protection that is suitable for the task at hand if you ask for it.

The Upper Action Level (85 decibels)

At this level, your employer must provide you with hearing protection, and you have to wear it - it is not negotiable; it is the law.

The Exposure Limit (87 decibels)

This, then, is the absolute maximum level of noise you can be exposed to in a day that is set out at the time of writing, and that's taking into account the protection you're wearing.

To Be Compliant

To make sure you comply with these safety regulations, all professional hearing protection sold in the UK must be CE or UKCA marked and meet a specific European Standard: EN352.

This isn't just a suggestion either; it's a legal requirement that guarantees the product has been officially tested to meet those standards.

This certification then confirms the product's advertised protection rating (its SNR), so you can be confident that the level of sound attenuation it provides you will be on par with your expectations.

Pro Tip: You should also always check for the EN352 mark on the product or packaging to ensure you are using compliant and tested safety equipment as well.

So How Do You Choose the Right Gear for Your Ears?

Not all hearing protection is created equal; as a result, you need to pick the right tool for the job with the correct level of protection and features that you need.

Consequently, one of the key things to look for is the SNR, which stands for Single Number Rating.

What's this SNR All About?

The SNR is a number that tells you how much a hearing protector will reduce the noise level in decibels (dB).

For example, if you're in an environment with a noise level of 100dB and you're wearing protection with an SNR of 25, the noise level reaching your ear will be about 75 dB - 25 decibels less.

As a result, it's important not to 'overprotect'.

You still need to be able to hear what's going on around you, like fire alarms or people shouting warnings in any case.

The aim is to get the noise level at your ear down to between 70dB and 80 dB, and this will be where your individual risk assessments come into play to tell you the level of protection you need for your workforce.

As a result, your own risk assessments should come into play here before you choose the one for you.

This is because the risk assessment is a legal requirement here where, as an employer, you must measure the workplace noise levels.

This assessment will then determine the specific decibel (dB) exposure risk, which will then dictate to you the level of hearing protection you require and will make sure you can then choose the correct equipment that has the right SNR level.

Things to Consider For The Right Level of SNR Protection

Here's a rough guide to help you pick the right SNR for the job - however, this should not overrule your own risk assessments and should be seen as more of a rough outline, as your individual case will always be unique to your business.

Noise Level (dB)	Recommended SNR
85 - 90	Up to 20
90 - 95	20 - 30
95 - 100	25 - 35
100 - 105	30 or more

Features

Each item of hearing protection can come with varying features as well.

As a result, before buying them, you should consider what features you need for your items, and this could vary for different team members as well.

For instance, something to consider here could be based around:

Feature	What to Look For
SNR (Protection Level)	Check your risk assessment, and choose an SNR that reduces noise to the 70-80dB range. Don't overprotect.
Comfort & Fit	Consider materials, adjustable headbands, and dedicated comfort cushions. Here, you should also look for lightweight designs for all-day wear and good durability for long-term value as well.
Type (Muffs vs Plugs)	Muffs are easy for intermittent use, while plugs are better for long-term wear, in hot environments, or with other headgear.
Communication Needs	Do you need to talk to colleagues? if you do, then you should look for hearing protection that has 'Active Listening' or 'Situational Awareness' features or built-in two-way radios.
Wireless Features	If needed, look for Bluetooth connectivity for calls or audio streaming, and check for safety-certified volume limiters and battery life as well.
Compatibility with other PPE	You should always ensure your chosen protection works with your hard hat and helmet compatable models, safety glasses, safety goggles, face shields and visors or even your respirators without compromising the seal of any of them.

It's Got to Be Comfy

If your hearing protection isn't comfortable, your team is less likely to want to wear it properly, and that's when problems start, as protection only works when it's worn 100% of the time you're in a noisy environment.

That's why getting the right fit and feel is just as important as the SNR rating.

How to Find Your Perfect Fit?

For instance, an earplug that's too big will be painful, and one that's too small won't create a proper seal.

For earmuffs, the clamping force of the headband needs to be firm enough to block noise but not so tight it gives you a headache.

As a result, here you want to consider features that allow for a custom fit to be had, such as:

Adjustable Headbands

These then let your earmuffs be adjusted to fit individual head sizes and shapes comfortably.

Padded headbands then also reduce pressure on the top of the head as well for added comfort.

Material Matters

For earplugs, soft memory foam is a popular choice as it expands to the shape of your ear canal, while Silicone plugs are durable, reusable, and can be more comfortable for some, but the fit is key.

Weight and Bulk

Lighter-weight earmuffs are less fatiguing to wear for a full shift.

However, in hot and humid conditions, earplugs are often a more comfortable choice than bulky earmuffs, which can cause sweating.

Ergonomic Design

You also want to consider earmuff cups that are shaped to fit around the ear naturally and have soft, deep cushions.

Here, a good seal is needed, so you still need to make sure they work well with any other PPE you wear, like your safety glasses, for instance.

Hearing Protection with Communication Features

In many jobs, being isolated by your hearing protection is simply not an option.

As you need to communicate with your team, hear instructions, and be aware of warning signals, that is where more advanced electronic hearing protection starts to come in.

If that is a concern, here, for instance, you should consider products that come with features such as:

What is 'Active Listening'?

This clever technology is also known as the 'Situational Awareness' feature.

Here, electronic ear defenders then use external microphones to pick up surrounding sounds like conversation and alarms and play them through the speakers inside the earmuff - limited to a safe volume (usually around 82-85dB).

When a loud, harmful noise then occurs (like a machine starting up), the electronics instantly shut off the amplification, protecting your hearing as a result.

This then gives you the best of both worlds: protection from dangerous noise but awareness of your environment.

Built-in Two-Way Radios

For teams that need constant communication over distances, you can get ear defenders with two-way radios (PMR446) built directly into the headset.

This allows for clear, hands-free conversations between multiple team members, dramatically improving safety and efficiency in coordinated jobs as a result.

Wireless and Bluetooth Functionality

Another feature to consider when choosing the right hearing protection for you, especially in modern hearing protection products, is Bluetooth connectivity.

This is because these products can do a lot more than just block sound; they can also keep you connected wirelessly to other devices at the same time.

As a result, if this is something you need, then this will be a feature for you to consider looking for.

Use Cases

While many of the same principles apply, choosing the right hearing protection often also depends on the specific environment and task at hand.

Here, different situations really do present unique challenges, so it's key for you to match the equipment to your individual use case.

As a result, below, we will cover some of the most common industrial and personal applications to show you how they can differ here.

For Industry, Construction and Manufacturing

In demanding environments like construction sites and busy manufacturing plants, for example, hearing protection is just non-negotiable.

As a result, for these sectors, you really need equipment that is not only effective but also exceptionally durable at the same time.

As a result, you should consider robust ear defenders that can withstand knocks and scrapes, for instance.

Given the frequent need for hard hats as well here, choosing specific helmet-compatible models is also often essential to make sure that a proper acoustic seal isn't broken.

Due to the need for clear team communication for safety and efficiency, electronic ear defenders with active listening or built-in two-way radios are often the best investment as well.

For the DIY Enthusiast

The noise from home improvement, or DIY, projects can be just as harmful as industrial noise, yet it's often overlooked.

For instance, a power drill can reach 100dB, and a circular saw can be even louder — well into the zone for potential hearing damage.

For the avid DIYer, a reliable pair of general-purpose ear defenders is a workshop essential really.

For shorter, loud tasks, a box of high-SNR disposable foam earplugs offers you a more convenient and effective solution to ensure you're protected while you work.

Ear Muffs or Ear Plugs How Do They Differ?

Now, let's look at the two main types of over-ear hearing protection: ear muffs and ear plugs.

Ear Muffs (or Ear Defenders)

These are the ones that look like a pair of headphones, and they have hard cups with soft cushions that seal around your ears to block out the noise.

As a result, they are great because they're easy to put on and take off, so they're good for when you're moving in and out of noisy areas.

Ear Plugs

These in-ear protection products then go right into your ear canal, and you can be disposable ones made of foam that you can then order refills for that you roll up and let expand in your ear, or reusable ones made of silicone or plastic.

As a result, these are small, light, and good for wearing for long periods of time.

Pro Tip: Always make sure your hands are clean when you're handling them to get the best fit and protection.

How to Get the Fit Right?

Even the best hearing protection won't do its job if you don't wear it properly.

To help you get the best fit possible, here are some handy tips to help you here:

For Foam Ear Plugs

1. With clean hands, roll the earplug between your thumb and forefinger into a thin, tight cylinder.
2. With your other hand, you should then reach over your head and pull the top of your ear up and back - which straightens out your ear canal.
3. Quickly insert the rolled-up earplug into your ear canal.
4. Hold it in place for 30 to 40 seconds while the foam expands to create a snug fit.

For Ear Muffs

1. Make sure the cups fully enclose your ears.
2. Adjust the headband so it's a snug but comfortable fit. It shouldn't be too tight or too loose.
3. Make sure there’s nothing blocking the seal of the cushions, like your hair or the arms of your glasses.

Tip to Look After Your Hearing Protection Kit

Just like any other bit of PPE safety gear, you really need to look after your hearing protection items, as this allows you to keep your running costs down with frequent replacements, and get the most from them.

For instance, here you should:

Keep it Clean

Wipe down your ear muffs regularly, and never use dirty earplugs.

Here, as well, many reusable silicone earplugs are also fully washable with soap and water, which is essential for hygiene.

Check for Damage

The cushions on your ear muffs can get hard or cracked over time, and the headband can lose its tension as well.

Reusable earplugs can also get damaged, and if these happen, then you should consider an immediate replacement to make sure that they still offer you the specified level of protection.

Pro Tip: Look for products with replaceable parts, like comfort cushions and hygiene kits for earmuffs, as this will also help you to improve the long-term durability and lifespan of your initial investment as well.

Store it Properly

You should also store your hearing protection in a clean, dry place when you're not using it as well to prevent them from getting damaged accidentally.
