Ear Protection for Using Power Tools And Loud Machines

Don't take any chances when working around power tools and ensure you wear the best ear protection available today:

There are two types of ear protection: plugs and muffs.

Muffs are generally worn over a person's entire head while plugs are usually worn in the ear

Both are designed to block sounds and protect your hearing. They keep your hearing intact and make it possible for you to continue working safely.

Best Power Tool And Loud Machine Hearing Protection.

When working with power tools, safety has to always be a primary consideration. Everyone wears safety goggles to protect their eyes, but fewer people wear ear muffs or plugs to protect their hearing.

Power tools make loud sounds, which will damage your hearing. This damage is not repairable. All of this can easily be avoided by wearing the best ear protection for using power tools. They are inexpensive and will last you for years!

This article will give you all the information that you need to help you choose the right pair of ear defenders, for when working with power tools and making some brilliant suggestions.

Noise Reduction Rating (NRR)–Measuring Ear Protection When Using Power Tools.

When you wear headphones and earplugs, they will block off some external sounds. But how do you know if they are blocking enough of these sounds, and how do you know if you actually need them at all?

Well, power tools are going to be loud. The Occupational Safety and Health Administration (OSHA) of America recommend that hearing protection is worn when working in an environment of over 85dB. (See the infographic below for some idea of how loud every day’s sounds are). You can also get free sound meters for your smartphone. These will give you a reasonable idea of how loud noises are if you want to be a little more accurate.

As a rule of thumb, when talking to someone who is at a distance of arm’s length, you should not have to raise your voice. If you need to raise your voice, then you should wear ear protection. Almost all power tools are way over 85dB in volume. So get yourself some suitable ear protectors if you are going to be using power tools.

Earmuffs and plugs have an NRR rating (Noise Reduction Rating). This measurement tells you how much a sound is reduced when wearing the ear protection. One point of NRR equals 1 decibel (dB) reduction in sound.

So if you are wearing a set of 25NRR ear muffs in a very noisy environment of 100 decibels, your ears will pick up (100-25) 75dB of that sound, which is well within the safe limits.

Proper ear protection will be between 15-30 on the NRR scale.

Loss Of Hearing On The Job.

Hearing loss is one of the most common injuries, and one that can be easily prevented. Hearing protection is a must, especially when working with power tools or loud machines.

More and more people realise audiologists can help prevent hearing loss from occurring as well.

The best viable tool for protecting your hearing when using expensive power tools or loud machines is a high-quality set of earplugs. The plugs are lightweight with an ear canal seal so the noise cannot get inside your head or ears, protecting your hearing from damage caused by excessive exposure to noise levels.

There are 3 ways that loud noise can permanently damage your hearing:

Shout 6 Feet Away To Be Heard.

If you have to shout to be heard from 6 feet away, then it is too loud. Most power tools and loud machines produce noise levels around 100dB or more and you can damage your hearing after just 15 minutes’ exposure to noise like this.

Ringing In The Ears.

After you stop working, you will hear a ringing in your ears. It could also sound like someone has a radio on very loud in the background. This is temporary and will go away after you stop working. If you are still hearing ringing 24 hours later, you are at risk of permanent hearing loss due to noise exposure.

Myths About Hearing - Tool And Loud Machines.

If you think that your hearing is in danger, you might try to cover your ears and ignore the noise. This isn’t a good idea because it will only make the damage worse.

Myth 1 - Build Up A Resistance.

If you just keep working, you can build up a resistance to the noise. Most people know that this is only a myth so they will use earplugs to prevent their hearing from damage.

Myth 2 - Noise Can Hurt Me Unless Its Loud.

You remember that noise isn’t the only factor that can cause damage. Many people believe it is the loudness of the noise that hurts their hearing, while the time you are exposed to it is what hurts it.

If you are in one of these jobs where you will be regularly exposed to high noise levels, then definitely wear a set of earplugs and a hat with protection on it.

Myth 3 - I Can Duck In And Out Of A Noisy Place Before It Can Effect My Ears.

Even if you can only be in the noise for a short amount of time, it could still cause damage. You might have heard of tinnitus, which is ringing in the ear. This is often caused by exposure to loud noises and they can last from a few hours to few weeks or even longer.

Myth 4 - My Hearing Will Come Back If I Avoid Noise.

If you are exposed to very loud noise for a short amount of time, it can cause permanent damage.

Types Of Ear Protection - Tool And Loud Machines.

There are a variety of ear protection that you can use. Not all of them are suitable for everyone, so it pays to find the best one for your needs and your chosen job.

Ear Plugs.

Ear Plugs are the most common way of protecting your hearing. They can be made from different materials like silicone, foam, or wax. Most people prefer the foam ones because they are comfortable to use. Some plugs come with a cord that goes around the back of your head and then you put them in your ears.

Ear Muffs.

Ear muffs are like hearing protection muffs. They are different because you cover your ears and not your head. This is because the ear muffs fit over your ears and should not go behind your head. They don’t have ear flaps so they don’t impede your hair or clothing.

Ear Caps.

This only helps to stop you from getting your hair wet. The ear caps are connected to some elastic and these go around your hair. The next time you wash your hair, remove the ear caps and then dry your hair. Ear caps can only protect from very high noise levels, which is why they are rarely used.

Types Of Ear Plugs:

Again, there are various types of earplugs on the market, but the most common are listed below:

Foam Ear Plugs.

Form Ear Plugs are the most common type of ear plugs made from foam. They are cheap to buy and they are also comfortable to wear.

Silicone Ear Plugs.

Silicone Foam Ear Plugs help to protect your hearing better than foam ones. They are more expensive than foam ones, but they last longer and they help to protect you from loud noises for a longer time. They are easily available in shops and also online. The only problem is that they aren’t as comfortable as the foam ones.

Wax Ear Plugs.

To protect your hearing from very loud noises, you want to use wax ear plugs. These are different because you can easily mold them to fit perfectly in your ears. This is the best type of ear plug for people who have sensitive or painful ears. It will help protect your hearing from damage caused by loud noises, but it will also help to relieve pain and discomfort due to noise exposure.

Bluetooth Earplugs.

Bluetooth ear plugs are the next generation for protection from loud noises. You can control these with your smartphone and you can connect 2 or more to different devices so they will work together. This is ideal for using them when you need to turn down the volume or raise the volume of music as you move around and you switch between devices.

Hearing Loss Caused By 3 Things - Tool And Loud Machines.

The 3 things that can cause damage to your hearing are:

Decibel Level.

Noise levels over 100dB cause hearing loss. This is because the noise causes lots of vibrations in your ears and these vibrations can damage your hearing. If you are exposed to a noise level over 90dB, your hearing could be damaged. It is recommended that you should use ear plugs if the decibel level is greater than 85dB.

Length Of Exposure.

If you are only exposed to noise for a short amount of time, you will be less likely to suffer permanent damage to your ears.


If you are only exposed to loud noises for a short amount of time, then you will be less likely to suffer permanent damage to your ears. The older you are, the less likely it will be that you will suffer any hearing loss due to noise.

This is mainly because your ears have a better ability to compensate for damaged hearing compared with children or teenagers. If you are exposed to noise for over 4 hours, then your ear can become permanently damaged and this will affect the quality of sound that you hear in the future.

Features To Look For In Ear Protectors.

When you are buying ear protection, the key criteria usually is how much sound they block out. But there are a lot of other nice to have features to consider. Some of them are listed below.

  • High NRR–This is what the ear protection is for. It needs to be suitable for power tools so should have an NRR of 20+
  • Comfortable–You may have to wear the earmuffs for long periods of time, so you want the earmuffs to be padded and also the headband.
  • Hardhat–If the earmuff has to be used with a hardhat, the headband must be able to go under, or behind the hard hat.
  • Easy height adjustment–allowing the muffs to be placed at the correct height for the size of your head, giving the maximum hearing protection
  • Speakers–Headphones with speaker can will enable you to listen to the radio, music or phone calls when you are wearing them
  • Microphone–with an integrated microphone, you can issue voice commands to the unit. For playing music or answering phone calls.
  • Bluetooth–Allows you to pair the headset with your smartphone. Doing this allows you to stream music, hear alarms and make phone calls without having to touch your cell phone.
  • Ariel–Allows you to get better radio reception

But again, the feature that is most important is the amount of sound that is blocked

Typical Power Tool Volumes.

The Occupational Safety and Health Administration (OSHA) states that hearing protection should be used if the volume is above 85dB for a period. Below are some power tools and their average volumes. As you can see, they are all above the safe limit for hearing. Having hearing protection with an NRR of 25+ would bring these to safe levels.

  • Muffler 90dB.
  • Screw Driver 91dB.
  • Orbital Sander 92dB.
  • Drill 93dB.
  • Jig Saw 98dB.
  • Grinder 100dB.
  • Miter Saw 104dB.
  • Hammer Drill 105dB.
  • Circular Saw 106dB.
  • Reciprocating Saw 105dB.
  • Impact Wrench 107dB.

How Power Tools Damage Hearing.

Your hearing ears are very delicate sense. Basically, it works by vibrations in the air hitting your eardrum. This vibrates tiny hairs in the inner ear, and the brain senses these vibrations and converts them into what you perceive as sound.

When you are a child, your hearing is excellent, everything is in good working order. But as we are exposed to loud noises (and some other external factors like blows to the head), some of these thousands of hairs can break off. Each one represents a tiny amount of damage that is done to your hearing.

Each individual breakage that you get will be unnoticeable to you, but as more and more damage is done, it becomes noticeable–and this damage is accumulative. That’s why your kids can hear the TV fine, but your older relatives have hearing problems. All the damage that has occurred to their ears through their life has built until they have trouble hearing.

Anyone exposed to loud noise more often will have worse hearing, for example, people who shoot, and of course people who use noisy power tools.

You notice that other than hearing aids, there is not much that can be done for people with damaged hearing. If you have it, it can also reduce your job opportunities. Some jobs do not allow the hard of hearing for safety reasons. Also, if you interview two job applicants who were very similar, but one of them was hard of hearing, which one would you hire?

Hearing need not be a problem. Wearing ear protection when using power tools is easy and inexpensive, so save your hearing now!

What Are The Four Basic Types Of Hearing Protection?

  1. Pre-molded (preformed) earplugs.
  2. Custom-molded earplugs.
  3. Roll-down foam.
  4. Push-to-fit.

For hearing protection for power tools & loud machinery, we would recommend the pre-molded (preformed) earplugs, or the custom molded earplugs. with general work use, either of these will suffice. For jobs requiring greater than 85 decibels, we recommend using a custom molded earplug. However, any earplugs will do.

How Do I Choose Hearing Protection?

The selection of hearing protection is based on several factors. These factors include the type of work being performed, noise level, duration of use or exposure, and cost. The most important factor in choosing hearing protection is sound levels.

Sound level can be measured using a device called a sound level meter (SLM). SLMs can be found at many industrial supply stores, however, they are very expensive. A cheaper alternative is the use of a sound level meter app for your mobile phone, or a handheld electronic noise meter (ENM).

These are much cheaper and you can purchase them at most hardware stores.

How Does Sound Affect My Ears?

Sound affects your ears in two different ways, one is temporary, and the other is permanent. Temporary hearing loss occurs when continuous loud sounds affect your hearing for a limited period.

Temporary hearing loss usually lasts from one to three hours after you are removed from the loud noise, but could last as long as 24 hours.

Permanent hearing loss is caused by exposure to excessive noise over a longer time, usually several weeks or months.

Recommended Earmuffs 3M WorkTunes With Bluetooth Technology.

My recommended choice for ear protection when using power tools is the 3M WorkTunes With Bluetooth Technology. These earmuffs cover just about everything mentioned and are a very reasonable price.

  • Noise Reduction Rating 24 NRR 24 to help protect your hearing.
  • Integrated Microphone Make and take phone calls without having to re-move the headset.
  • Hi-Fi Sound 40 mm high-fidelity speakers for premium sound quality.
  • Bluetooth Technology stream music from mobile phones or other Blue-tooth devices.

Conclusions - Best Ear Protection For Power Tools.

In conclusion, the “power” in power tools causes these devices to make a lot of noise. This noise WILL damage your hearing over time as you are exposed to more loud noises.

Your hearing is very delicate and cannot really be repaired once it has been damaged, so it is worth looking after. You do not want to be like me in a few years and be continually raising the TV volume because the talking is too quiet, and you can’t hear it, then lowering the volume again because the music is too loud.

Wearing ear protection when using power tools is easy! Anyone can do it. Also, ear protection is not expensive and will last you many years.

So what is your excuse for not using it? Get some ear protection for when you are using your power tools now!

People Also Ask.

Are Ear Plugs Better Than Earmuffs?

Earplugs offer greater protection from sound than earmuffs, as they fit directly into the ear canal, blocking more noise. Earmuffs, however, block enough noise to still protect your hearing. They also are more comfortable over time and offer some protection to the ear from flying pieces of debris.

Most people find that when working with power tools, ear muffs are the better choice, but it is really down to each individual’s preferences.

What Could Prevent Earmuffs From Providing Your Ears Good Protection From Noise?

Earmuffs need to go over the whole ear and form an airtight seal around them. A headband connects the two earmuffs and holds them in place. If the earmuffs are too small, or the headband is not adjusted correctly, then the seal is not successfully made, so the amount of sound blocked is less than expected. The earmuffs should also be adjustable so that they can fit the user's head perfectly, and should not be too heavy.

Ear muffs are used by military, law enforcement, fire fighters, industrial workers, construction workers and even in some sports competitions.

In A Very Noisy Environment, What Is The Best Ear Protection?

To give your ears the best level of protection from sound, the best solution is to wear a pair of in-ear plugs, with a suitable set of earmuffs over the top of them. This gives you two levels of protection from loud sounds.

The Noise reduction (NRR) is not the values of the two sets of ear protection combined, however. You just add 5-10db to the best pair.

For example, if you had earplugs rated 30 NRR and muffs rated 25 NRR, then the effective sound reduction is 35-40dB, not 55dB. Even though this is the case, it is still blocking a lot of the external sounds, giving excellent protection.
