My best recommendations for hearing protections for woodworking. Understand what to look for in them and how to choose the best ear protection that works for you.
Safety is the most important part of any woodworking project. You only have one body, and it is essential to protect your eyes, ears, and airways from long-term damage from all the generated dust.
Let’s talk about hearing protection today. Nothing can restore lost hearing. Once it’s gone, it’s gone.
Why do you need hearing protection?
Human hearing can be significantly reduced by exposure to loud noises. According to OSHA, 85 dBA is the limit above which hearing loss becomes permanent.
This means that being exposed to 85 dBA for 7 hours can cause permanent hearing loss. Not just that, with every 3 dBA of noise increase past 85 dBA, the time hearing loss reduces in half.
Without hearing protection, at 95-100 dB (like a circular saw, table saws, etc.) would take 7 minutes, and at 112 dB (like a chain saw) would take only 2 minutes!
Protecting ourselves from hearing loss caused by loud noises is something in our control and something we can do.
How to choose hearing protection
Many factors play a role in how you decide what ear protection you pick.
Noise Reduction Rating
This is THE most important feature to look at when picking ear protection. Every ear protection has an NRR (Noise Reduction Rating). Why does it matter? This number defines the amount of noise it blocks out. It can go as high as 33, with 23-27 being the most common. The actual effect of NRR isn’t a straightforward subtraction calculation.
How to calculate noise reduction
To calculate the actual noise reduction from your ear protection, you want to subtract 7 from the NRR and then divide by 2. Therefore, if the hearing protection is rated at NRR 27, the actual noise reduction is not 27dB. It is (27-7)/2, which is 10 dB. This is the reduction in the noise you will see.
If you are using shop tools, they are most commonly around 95dB, hearing protection will deduct 10dB from it, bringing it down to the safe 85dB safe.
Remember that the NRR is only true when the hearing protection is worn correctly.
Style of hearing protection
Ear protection comes in two styles –
- Over the ear style (ear muffs)
- In-ear styles (like earplugs)
They both have their advantages and drawbacks. Over-the-ear styles can easy and quick to put on but can apply force to your ears and head and can become too hot in the summer months. On the other hand, in-ear styles are smaller but can apply pressure in the ear canal and may not be comfortable for long periods of wear. Which style you choose is ultimately your personal preference, but there are a few other factors to consider before making the decision.
Compatibility with other PPE
When using shop tools, you need eye and breathing protection in addition to hearing protection. You want to make sure that all three work together and do their individual jobs. If not worn correctly, the respirator or safety glasses might push down on the ear protection making it looser or vice versa.
Many newer ear protection devices come with built-in BlueTooth or FM radios. These are great features to add additional functionality if you need them but are totally optional. Obviously, the price goes up with these additional features as well.
Noise-canceling vs. noise isolation
Noise-canceling headphones are trendy and commonly available in many varieties and brands. These do not work for noise reduction and are not intended for use in a workshop.
Noise-canceling headphones listen for sounds through a microphone and then neutralize it before it reaches the ears by playing a different sound. This technology isn’t fast or accurate enough to cancel out the noise from power tools.
On the other hand, noise isolation devices simply don’t allow the noise to reach your ears, making it a lot more effective and accurate for use around workshop tools.
Best hearing protection for woodworking
Picking the right hearing protection is all about your preference based on the considerations above and your budget.
Here are some of the best options in the market for every style and budget:
- Decibel Defense – Over-the head earmuffs with a high NRR.
- 3M Peltor Earmuffs – I have used these before and liked them.
- ISOTUNES Link – Earmuffs with BlueTooth. I recently got these and like how they work. They are pretty rugged over-the-head earmuffs with BlueTooth and a microphone. The battery is pretty long too.
