OSHA standard: 29 CFR 1926.52 · 1926.101
At a glance
- Noise damage is painless, gradual, and permanent
- Raise your voice at arm's length? Loud enough to need protection
- Plugs and muffs only work worn correctly — a half-inserted plug is decoration
- Ringing ears after work means the damage already started
Introduction
Hearing loss is construction's quietest injury: it doesn't bleed, it doesn't hurt, and by the time you notice it, it's permanent. Saws, grinders, jackhammers, compressors, and heavy equipment all run past 85 decibels — the level where damage begins with a full shift of exposure. The fix costs a few cents a day and takes ten seconds. Today's talk covers when protection is required, how to wear it so it actually works, and the warning sign everyone ignores.
Know When It's Loud
- The field test: if you have to raise your voice to be heard at arm's length, you're in damaging noise
- The usual suspects: cut-off saws, grinders, chop saws, jackhammers, powder-actuated tools, compressors, equipment cabs with the windows open
- Damage stacks by dose: louder noise damages in less time — a chop saw can do in minutes what a loader takes hours to do
- Impulse noise (nail guns, PAT shots) spikes past safe levels instantly
Wear It Right
- Foam plugs: roll it tight, pull the top of your ear up and back, insert deep, hold while it expands — a plug sitting in the bowl of your ear blocks almost nothing
- Muffs: full seal against the head; safety-glasses temples and beanies break the seal — thin-temple glasses or plugs solve it
- Double up (plugs + muffs) for the loudest work: jackhammering, cutting in enclosed spaces
- Keep plugs clean; dirty plugs trade hearing loss for ear infections
The Warning Everyone Ignores
- Ringing, buzzing, or muffled hearing after shift is not "getting used to it" — it's the sound of hair cells dying
- Those cells never grow back; hearing aids amplify what's left, they don't restore what's gone
- Tinnitus — permanent ringing — is often worse than the loss itself; it never turns off
- Protect the hearing you have left: damage is cumulative, and stopping now stops the slide
Key takeaways
- 85 decibels for a shift starts the damage
- Arm's-length voice test: raised voice = protection on
- Roll, pull, insert — a shallow plug is a fake
- Glasses temples break muff seals; plan for both
- Double protection for the loudest tools
- Ringing ears = damage done; don't collect more
Questions for your crew
- Noise damage is painless, gradual, and permanent — 85 decibels across a shift is enough to start it.
- The arm's-length test: if you have to raise your voice to be heard at arm's length, it's loud enough to need protection.
- Foam plugs only work inserted right: roll, pull the ear, insert — a half-inserted plug is decoration.
- Glasses temples break muff seals — plan plugs, muffs, or both around your other PPE.
- Double up with plugs plus muffs for the loudest work: powder-actuated tools, demolition saws, jackhammering.
- Ringing ears after work means the damage already started — don't collect more.
