Walk into any small cabinet shop and the first thing that hits you is the sound. A table saw spinning up, a router screaming through a dado, a planer taking a heavy pass on oak, a miter saw barking once and then falling silent. Each of these machines on its own is loud. Together, in a room with hard walls and a concrete floor, they add up to something that can genuinely damage your hearing. Most cabinetmakers do not think of themselves as working in a hazardous environment. They think of dust, blades, and back strain. Noise rarely makes the list, and that is exactly why it does so much quiet damage over a career.
The numbers are worth knowing. A typical table saw runs around 90 to 100 decibels at the operator’s ear. A router can hit 100 or more. A planer or jointer often measures in the mid 90s. A shop vacuum or dust collector adds a constant 80 to 90 decibels of background drone. Safe exposure limits drop fast as sound rises. At 85 decibels, hearing protection guidelines suggest limiting exposure to roughly eight hours. At 100 decibels, the safe window shrinks to about fifteen minutes. A cabinetmaker running a router for an hour without protection has already exceeded a full day’s allowance several times over. The damage is cumulative and painless at first, which is what makes it so easy to ignore.
Hearing loss from woodshop noise usually shows up as trouble with high frequencies first. You notice it when you cannot follow a conversation in a noisy restaurant, when the phone sounds muffled, or when a persistent ringing follows you home after a long day of cutting. Tinnitus is common among tradespeople and often the first real warning sign. Over years, the loss becomes permanent. Hearing aids help but do not restore what was lost, and the social cost is real: strained conversations, missed cues, isolation. For a cabinetmaker whose livelihood depends on fine work and clear communication with clients, that cost is steep.
The good news is that hearing protection in the woodshop is cheap, simple, and effective. Foam earplugs cost pennies and reduce noise by 25 to 30 decibels when fitted properly. Earmuffs are easier to put on and take off and work well for intermittent loud operations. For the best result, combine both, especially around the planer and router. Electronic muffs that block loud noise while letting speech through are popular in shared shops. The key habits are simple: keep protection within arm’s reach of every loud machine, wear it every time, even for a single quick cut, and teach apprentices to do the same from day one. A shop culture that treats earplugs like safety glasses makes the biggest difference.
It also helps to reduce noise at the source. Sharpen blades, tighten loose guards, mount machines on rubber pads, and line hard walls with sound-absorbing material. Move the loudest equipment away from workbenches where people spend hours. Take breaks from continuous machine runs. None of this replaces hearing protection, but it lowers the overall dose. Get a baseline hearing test when you start in the trade and repeat it every year or two. What you protect now is the hearing you will still have in twenty years, and for a cabinetmaker, that is worth every pair of earplugs in the shop.
