What are the best earplugs for factory workers?

With hearing protection, most people’s first thought would immediately go to industrial workers; whether it be airport workers, factory workers, manufacturing workers, they are the leading examples of hearing protection.

Most employers do at least recognize and supply with earplugs or earmuffs to protect hearing. Still, they don’t always fit for the level of noise a worker is exposed to, and all have their advantages and disadvantages.

Unbelievably, certain employers are careless in providing any type of hearing protection or earplugs. There is a percentage of workers who just don’t like wearing them for their own reasons and neglect their own hearing protection.

Who’s at risk?

Who is at the highest risk of developing noise-induced hearing loss (NIHL) from their job? Here is a list of why previously mentioned occupations are susceptible to hearing damage

  • Construction Workers: One of the largest groups to declare hearing loss claims each year, construction workers are subjected to noise during the whole day on construction sites from machinery, heavy vehicles, and power tools.
  • Factory Workers: The ongoing din of machinery, tools, and people yelling all over makes manufacturing one of the most prevalent industries associated with hearing loss.
  • Truck Drivers: Sitting in a loud truck for several hours a day could affect anyone’s hearing. You have to count in the engine noise, noise from the brakes, the wind noise, noise from handsfree and other communication devices, tire/road noise, and noise from other vehicles.
  • Rail Transport Employees: A study in Australia in 2006 found that rail workers suffered hearing loss at 12 times the average national rate. The research has also shown that the possibility of deafness for rail transport employees was a lot higher than those of other transport types (air and water).

Can you rely on hearing protection alone when carrying out noisy work?

You should not rely on hearing protection alone to control noise exposure. Hearing protection serves as extra protection after using noise control techniques (such as terminating noisy tasks, substituting quieter processes, replacing loud equipment, and removing people from noisy areas)

If hearing protection is still necessary after taking these measures:

  • be sure the protectors provided give sufficient protection – try at least to get below 85 dB(A), but don’t provide too much protection as protectors which cut out too much noise will make it hard to keep a conversation, and that will result in an unwillingness to wear them
  • select protectors which are optimal for the working environment – think about how hygienic and comfy they are
  • consider how they will be worn with other protective equipment like hard hats and protective goggles
  • provide a variety of protectors so that employees can choose ones which suit them
  • make sure your employees are educated about noise and trained in how and when to use the hearing protectors
  • make sure your workers have their hearing regularly tested via annual audiometry exams and questionnaires

Noises When doing Industrial Work

The following infographic shows a list of the various noises when you are out and about. Any noise over 70-80db over a long period of time may cause damage to your hearing. A noise of over 120dB may cuase immediate harm to your ears

Types of Hearing Protection for Workers

The kind of hearing protection device to choose will rely on the amount and loudness of the noise you’re exposed to, workplace regulations, and what’s comfortable to wear. By law, hearing protection devices have to be labeled with a Noise Reduction Rating (NRR) based on their capability to reduce noise.

But bear in mind that the best hearing protection isn’t the one with the highest Noise Reduction Rating, but the one that a person will continually wear when they are exposed to loud noise.

Most common types of protection

Foam earplugs

Definitely the cheapest option out there; they are soft and comfortable. Foam earplugs are the most popular earplugs today. They come in all shapes, colors, and sizes. Usually, they are the most efficient for blocking noise.

However, since they are made of porous material, they're a breeding ground for bacteria, so you have to replace them regularly.  The advantage is that they Fit many different ear canals, and they are convenient and disposable. Their disadvantage would be that they won’t provide proper protection if not inserted correctly, and the user may not even realize when the plug doesn’t make a good seal.

Silicone plugs

Soft silicone plugs are light, comfortable, and reusable (just rinse them in cold water). Some people find them less effective at filtering out noise than other types, but it’s all up to the person. They usually are a bit pricey. Their pros are that they come in different sizes, they are reusable, and pretty convenient. Cons would be that they offer worse protection than foam ones and you’ll have to wash them regularly.


They are incredibly easy to use, unlike foam earplugs. Besides protecting the ear canal, they also protect the entire ear. Earmuffs can be combined with earplugs for extra protection. The good thing is that one size fits all, they are comfortable to wear for more extended periods, but the disadvantage is that they can get warm in hot working environments or during the summer.

Earmuffs may also not fit very well with protective headgear and goggles. In addition to this, to communicate, a worker will remove them or remove one ear, exposing them to damaging noise volumes.

Custom earmolds

Made to fit perfectly in the user’s ear. They are reusable, washable, and pretty much ideal for long-term use. They can be made to reduce sounds over certain decibels, so you can normally hear conversations while still protecting your ears from loud machinery or construction.

They cost more than foam earplugs, but the good thing is that the price is often covered through an employee insurance plan.

Health and Safety in the workplace

One of the most important parts of a factory worker’s life is to be aware of hearing protection. Hearing protection is so important because you are not only protecting your ears, but also your family and friends. Protecting your hearing from loud horns, machines and noisy people is something that should be very personal for everyone.

The introduction to this blog post will go over how industrial workers can keep their hearing protected while working at a factory.

What the worker wears, such as ear plugs or ear muffs should depend on how loud the noise they will be working around it.

Ear plugs

Ear plugs can be found at earphone shops and are very cheap to buy but they are not great for everyone. A big problem with ear plugs is that they can be uncomfortable and cause pressure in the ears. If you put on an ear plug, you cannot hear the loud noise around which can become dangerous or even fatal.

In case you’re working in an environment that has a lot of loud noise, it’s important to know how to use hearing protection devices, such as earmuffs or heavy duty noise cancelling headphones. It is also recommended that no one uses these types of hearing protection devices if they are not comfortable with them because they can do more damage than good if used incorrectly.

Heavy Machinery

There are many power tools that can be dangerous if used incorrectly. These power tools include circular saws, metal shears, grinders/polishers, and pneumatic drills. All of these machines should have guards installed to protect workers from their blades or other moving parts.

A worker who has reached the end of his shift should never leave unsafe machinery running in a production area (and always wear protective gear).


Eyes Injuries can occur when proper eyewear is not worn, such as the case of a broken lens or an unshaded light. An eye injury can lead to loss of vision, so it is very important for the actual eyes and the safety of work.


Toes, heels, or the feet can be injured by a small piece of equipment that has broken off or by stepping into a hole. Most of the time people do not realize how much damage they can do to their feet until after they have hurt themselves. That is why it’s so important to wear the correct footwear. Footwear must be sturdy enough to protect you from sharp objects and small materials which can cause serious injury.

Food and Drink

When people drink alcohol at work, it often results in an injury caused by impaired judgment or even aggression. If drinking is a common activity at work, it is important to have a designated driver. This rule applies to all factory workers, regardless of how much they generally enjoy their job.

How Noise Can Affect Workers

Even though the purpose of a factory worker’s job may be to create, produce and/or assemble something, there is still a risk of hearing damage when they are working around loud noise. Some things that will make noise include: machines, air horns used as warning signals and emergency devices such as fire alarms. These noises can be constant or can come in short spurts for short periods of time.


Hands When a bolt comes loose on a machine, it can easily rip off someone’s fingers or hands. A worker who turns his back to a machine while it is in operation can easily be hurt by the moving parts of the machine. It is important for workers to understand why they use certain safety equipment and clothing so they can stay safe and protect others at work too.

The workplace is not designed to be dangerous, but with the right information, workers can protect themselves from any type of accident. Making sure that everyone knows how to use their protective gear will save lives in the long run because people will avoid getting hurt from using tools that are not made with correct safety materials.

Health & Safety

The Health & Safety section of the handbook will provide information about injuries and potential hazards in the workplace. It is important to pay attention to any injuries that are incurred because they could be a sign of something more serious and require immediate medical attention.

Everyone should know where to go if an injury occurs in the workplace. It is also a good idea for everyone to have a first aid kit at home, just in case an injury is sustained in the workplace.

How Things Are Meant To Be Used

There are times when tools or machines are not used correctly. Large machinery, such as grinders and drills can be extremely dangerous if people do not know how to use them properly or do not wear safety gear. Working around these machines can cause heavy injuries or death when they snap and there is no place to run from it.

Hygiene and Risks of Infectious Diseases

Healthy employees are the key to a healthy workplace. Having clean hands and a clean uniform helps to protect other people from diseases that could be spread through germs in the air or through your work clothes. Without knowing proper hygiene, it is easy for dangerous diseases, such as tuberculosis or the flu, to spread through an office environment.

How to Protect Your Body From Injury During Work Related Activities

One of the most important things that people can do to stay safe is to always wear the appropriate protective gear when there is risk of injury involved with doing their job. Certain regions have special safety requirements that need to be followed, such as wearing a hard hat when repairing electrical equipment.

It is also very important to know the proper form when lifting heavy objects and how to safely move those objects without dropping them.

How To Protect Yourself From Workplace Violence

Workplace violence can mean many different things. There is physical violence, verbal violence and even cyber-bullying on the internet.

These are all forms of abuse that happen in an office environment and can be damaging for employees who are affected by it. The best way to protect yourself from these types of workplace problems is through proper training and education on the subject.

Final words

Certain high decibel exposures may be unavoidable to carry out the tasks required for some operations, but that doesn’t mean that employees do not require extra protection, and employers must have that in consideration.

  What workers do in their free time, like attending a rock concert, go to a shooting range or other high sound exposures is their decision, but noise protection at industrial work is mandatory.

Please Note: Just because an ear defender is marked, for example, "Gunshot" - it will still cover other things, like "explosions"

Other Questions

How can I Protect my Hearing at Work?

Some working environments are very noisy. Steel factories, airports, and mills are good examples of typical noisy work environments. You can't survive in such an environment for long unless you protect your hearing.

Safety and regulation authorities recommend the best ear protection for such noisy workplaces. They include earplugs and earmuffs. Both serve the same purpose, but they look different. Earplugs sit inside the ear, giving you comfort and ambient noise reduction. While earmuffs cover the whole ear from outside.

Earplugs are light in weight, durable, and portable. Recommended as the best for factory use due to their simplicity.

Is there an alternative to earplugs?

Earplugs are hearing protection devices placed inside the ear. They are of different types and materials. Some people don't like them because they feel like foreign objects inside the ear. Due to this discomfort, people look for other alternatives that serve the same purpose.

Alternatives for earplugs are available. They include sound panels, a white machine, headbands for swimming, noise-canceling headphones, isolation headphones, and earmuffs.

In environments such as factories, earplugs are best. Because they are easy to use, durable, comfortable, and portable.

Are there any earplugs that block all noise?

Earplugs reduce noise getting into your ears. When they completely block noise, your ears become numb. So, there are no earplugs that completely block noise because of the said reason.

Noise Reduction Rate (NRR) is the level at which earplugs can reduce noise. The best earplugs have decibels of between 21and 34. That’s according health and safety regulations.

Best earplugs reduce surrounding and ambient sound while still keeping your ears comfortable. They balance noise inside and outside your ear. They have silicone material, which allows them to fit well inside the ear without slipping.
