Woodworking is an inherently noisy activity, whether you’re using power tools like table saws, jointers, and planers or just hand tools like chisels and hand planes. The high noise levels in woodworking shops can cause permanent hearing damage over time if you’re not wearing proper hearing protection.
Choosing the right hearing protection is important for woodworkers to prevent hearing loss while still allowing you to communicate and hear warnings or machine sounds. There are various types of hearing protection made for different noise levels and environments.

Why Hearing Protection is Important in Woodworking
Unprotected exposure to loud noises over 85 decibels for extended periods can cause noise induced hearing loss. The safe noise exposure time is cut in half for every additional 3 decibels. Some common noise levels in woodworking are:
| Tool | Noise Level (dB) |
|---|---|
| Router | 85-95 dB |
| Circular Saw | 90-105 dB |
| Table Saw | 95-110 dB |
| Band Saw | 95-105 dB |
| Jointer | 95-105 dB |
| Planer | 100-115 dB |
As you can see, most woodworking tools produce noise levels above the 85 dB threshold where hearing protection becomes necessary. Table saws, jointers, and planers are especially noisy.
Extended exposure to loud shop noise can lead to tinnitus (ringing in the ears), inability to hear high frequencies, and overall deafness. Wearing proper hearing protection when working with noisy tools reduces your noise exposure and protects your hearing.
Types of Hearing Protection for Woodworking
There are a few main types of hearing protection suitable for woodworking:
1. Earplugs
Earplugs are inserted directly into the ear canal to block noise. They come in various designs:
- Foam earplugs – Cylindrical foam plugs that compress when inserted in the ear canal. They effectively block noise and are very affordable.
- Custom molded earplugs – Made from silicone or acrylic material molded specifically for your ear canals. More comfortable for extended wear.
- Insert earplugs – Rigid or soft flanged plugs on a stem that insert into the ear canal. May be reusable.
Benefits of earplugs:
- Inexpensive
- Convenient to carry and wear
- Offer good noise reduction
- Disposable types don’t require maintenance
Considerations for earplugs:
- Can be uncomfortable with extended wear
- Difficult to insert and remove with dirty hands
- May not fit properly in everyone’s ear canal
- Can obscure lower noise frequencies
2. Earmuffs
Earmuffs completely enclose the external ear for hearing protection. Key features:
- Hard plastic cup surrounds the ear and soft foam or liquid cushions seal against head
- Adjustable headband holds earmuffs in place over ears
- Attenuate noise through absorption and blocking entry into ear canal
- Available with standard or high attenuation levels
Benefits of earmuffs:
- Seal securely and comfortably around the ear
- Allow normal conversation while blocking loud noise
- One size fits most people
- Easy to put on and remove
- Reusable for years
Considerations for earmuffs:
- Can get hot during extended wear
- Bulky around the head which limits mobility
- Hair and eyeglasses can break the seal and reduce protection
- Usually more expensive than earplugs
3. Hybrid Hearing Protection
Hybrid hearing protectors combine an earplug with an earmuff in one unit to provide enhanced noise blocking. Popular options include:
- Electronic earmuff – Earmuffs with built-in microphones and speakers to allow ambient sounds through while damping loud noises. Allows face-to-face conversation.
- Cap-mounted earmuffs – Earmuffs attached to a cap or hard hat so they stay in the proper wearing position.
- Communication headsets – Headphones integrated with a microphone in the earmuff for two-way communication, often using a radio.
Benefits of hybrid hearing protection:
- Maximum noise blocking from dual protection
- Enhanced communication ability
- Versatile for many situations
- Great for prolonged wear comfort
Considerations for hybrid protectors:
- Most expensive option
- Electronic types require battery charging
- Cap-mounted design can be bulky and warm
- Not practical for occasional woodworking use
Noise Reduction Ratings
All hearing protection is rated by its noise reduction rating (NRR) measured in decibels. This indicates how much sound the protector can block. Typical ranges are:
| Type | Typical NRR Range |
|---|---|
| Foam earplugs | 28-33 dB |
| Custom earplugs | 25-30 dB |
| Earmuffs | 22-31 dB |
| Electronic earmuffs | 20-26 dB |
Higher NRR indicates better noise blocking. However, the laboratory testing conditions for NRR don’t reflect real-world results. Reduce the listed NRR by 50% or more to estimate the protector’s actual noise reduction in practice.
Closely matched earplugs and earmuffs provide 30-45 dB typical real-world attenuation as hybrid protection. This significant reduction makes hybrid options ideal for prolonged exposure to extremely loud tools like planers.
Key Considerations for Woodworking Hearing Protection
Selecting appropriate hearing protection for your woodworking involves:
Noise Levels
Consider the noise levels you’ll be exposed to, both continuous and impact noises. For occasional use with portable power tools, simple foam earplugs or earmuffs are adequate. Operating louder stationary machines like jointers requires higher protection ratings.
Comfort
The protector must be comfortable enough to wear for extended periods. Try different sizes and designs to find ones that fit your ear canals or head properly. Features like soft earmuff cushions enhance comfort.
Communication
You need hearing protection that still allows conversation and perception of machine noises or warnings. Electronic earmuffs are excellent for this, or lighter attenuation earplugs that block damaging noise levels while allowing speech.
Compatibility
Hearing protection should work with any other safety gear you need, such as protective eyewear, dust masks, and helmets. Some earmuffs are designed to be worn under hard hats.
Affordability
Cheaper basic earplugs and earmuffs work fine for occasional use. Invest in pricier custom or electronic hearing protection if you operate loud machinery daily.

Proper Use of Hearing Protection
To achieve their maximum noise reduction, use hearing protectors correctly:
- Roll and compress foam earplugs before inserting to fit shape of ear canal.
- Insert earplugs with clean hands and check fit seal.
- Adjust earmuffs to fit your head size and lightly press cups to create a tight seal.
- Replace disposable earplugs and earmuff cushions regularly.
- Take off hat or glasses before donning earmuffs to improve the seal.
- Store reusable earplugs or earmuffs in a clean case when not in use.
- Check electronic battery levels and recharge as needed.
- Always use hearing protection when operating loud equipment.
Wearing your hearing protection consistently and properly ensures you achieve the full noise reduction capability. Guarding your hearing from the high noise levels in woodworking shops now prevents hearing damage later.
Conclusion
Preventing noise-induced hearing loss should be a priority for every woodworker. The sustained high decibels produced when working with jointers, planers, table saws, and other machinery can quickly damage your hearing if unprotected.
Choosing suitable hearing protection depends on your noise exposure levels, budget, comfort needs, and work environment. Basic disposable earplugs and earmuffs offer affordable protection for occasional use. Electronic earmuffs and custom molded earplugs provide the best noise blocking for extended wear when woodworking daily.
Whichever hearing protector you select, be sure to use it correctly every time you work around loud noise. Wearing appropriate protection each time you’re woodworking will let you continue enjoying this hobby for many years without developing permanent hearing loss.
