If you run a small woodworking or cabinet shop, hearing protection rarely makes the top of the to-do list. But a table saw, planer, router, and dust collector running together can push your shop past the noise level where damage starts — and unlike a cut finger, noise-induced hearing loss is permanent and painless until it’s too late. The good news: protecting your crew (and yourself) doesn’t require a big budget or a complicated program.
Here are the top six hearing protection moves a small shop owner should make, roughly in the order that gives you the most protection per dollar.
1. Know your “85 dBA” line before you buy anything
In Canada, the widely used action level for occupational noise is 85 dBA averaged over an 8-hour day. At or above that exposure, employers are generally expected to take action — reduce the noise, limit exposure time, and provide hearing protection. The exact wording and limits vary by jurisdiction, so confirm the rule that applies to you (CCOHS keeps a clear summary of the occupational noise exposure limits across Canada).
Why this matters first: a planer or chop saw alone can sit in the 95–105 dBA range up close. Once you know roughly where your shop lands, you can stop guessing and choose protection that actually matches the job instead of buying whatever is on the shelf.
2. Start with disposable foam earplugs — the best value per box
For most small shops, a box of properly fitted disposable foam earplugs is the cheapest, highest-rated protection you can stock. Roll them down thin, pull the top of your ear up and back, insert, and hold while they expand. A good fit is the whole game — a plug that’s loosely jammed in gives a fraction of its rated protection.
The catch with disposables is consistency. Workers in a hurry often under-insert them, so a high lab rating on the package does not equal the protection you get on the floor. Keep them at every workstation so there’s never an excuse to skip them.
3. Add earmuffs for the loudest, on-and-off tasks
Earmuffs shine where workers move in and out of noise — running the planer for a minute, then stepping away to measure. They’re fast to put on and take off, hard to fit wrong, and easy to share across a shift (wipe the cushions down). For the loudest operations, earmuffs are often the more practical choice than re-rolling a plug every few minutes.
The trade-off: they’re bulkier, warmer, and can interfere with safety glasses arms, which break the seal. Browse a mix of plug and muff options in the broader hearing protection category so you can match the tool to the protector rather than forcing one solution everywhere.
4. Don’t trust the rating on the package at face value — derate it
The Noise Reduction Rating (NRR) printed on most packages is a laboratory number, achieved under ideal fitting conditions you will rarely reproduce in a busy shop. A common real-world approach is to derate that number — a widely cited rule of thumb is to take roughly half of the labeled NRR for everyday use, and apply an even larger discount for foam plugs that workers fit themselves.
Practical version: if a plug claims an NRR of 30, plan for closer to 15 dB of real protection. That keeps you from believing you’re covered when you’re not. It’s an estimate, not a precise measurement — if you have a borderline-loud shop, a noise assessment from a qualified person is worth more than any number on a box.
5. For very loud work, double up — but don’t expect the math to add
For the loudest moments — think large planer plus dust collector plus an air compressor cycling — wearing plugs and muffs together gives more protection than either alone. What it does not do is add the two ratings. Doubling up typically buys you only a handful of extra decibels (often quoted around 5 dB over the better single device), not the sum of both. Use it as a margin for the worst tasks, not as a license to stay in extreme noise longer.
6. Make protection automatic, not a daily decision
The cheapest improvement isn’t a product — it’s habit. A few low-cost moves go a long way in a small shop:
- Station the protectors where the noise is. Plugs at the saw, muffs hung on the planer. If they’re across the room, they won’t get worn.
- Pick comfortable options. Comfort is a safety feature — an uncomfortable plug ends up half-out or in a pocket.
- Keep a simple sign-off. Even a clipboard noting that everyone has protectors and knows how to fit them shows you’re taking it seriously, which matters if anyone ever asks.
- Lead by example. In a small shop, the owner not wearing protection sets the ceiling for everyone else.

The honest bottom line
Hearing protection is one of the few areas in a small shop where a small, consistent effort prevents a permanent, untreatable injury. Start by understanding roughly how loud your shop is, stock well-fitted foam plugs and a few muffs, derate the ratings so you don’t fool yourself, and make wearing them the default. If your shop is genuinely loud for long stretches, a one-time noise assessment is the smartest money you can spend — it tells you exactly how much protection you actually need.
