Hearing protection is everywhere: hard hats, vests, earplugs. The box is checked. But 40% of hearing conservation programs are failing, and most organizations don't know.
Why it matters
Occupational hearing loss is a slow, invisible problem. Workers wear the gear, pass their audiograms, and still lose hearing. The damage accumulates for years before anyone notices, and by then, it's permanent.
The problem
The label on a box of earplugs means almost nothing.
A worker recently fit-tested on a device rated at 28 decibels of noise reduction was receiving less than 10 dB of protection. With the right fit, she got over 22.
This gap in protection is typical. Protection levels vary based on ear canal shape, insertion technique, and device. One worker might exceed the manufacturer's rating. Another might get zero.
By the numbers
- Labeled Noise Reduction Rating (NRR) tested: 28 dB
- Noise attenuation with poor fit: < 10 dB
- Noise attenuation with correct fit: > 22 dB
A closer look
The most common mistake that workers make is failing to roll foam earplugs before inserting them. They shove them in, the plug sits halfway out of the ear canal, and the noise comes through anyway. Most often, no one corrects them because no one is checking for errors.
Training programs using slides and handouts don't fix this. Workers need to demonstrate correct technique rather than attend a presentation.
A practical solution: simpleFit® earplugs
As David Kopf notes in Occupational Health and Safety, hearing protection compliance hinges on ease of use. For example, traditional foam plugs require rolling before insertion, which can introduce industrial dirt into the ear canal and often causes an improper fit.
The simpleFit® reusable earplugs by Hexarmor eliminate this step. Handy guides let you insert them quickly and hygienically without rolling, even with gloves on. This ensures an exact, secure fit, solving the issues of standard soft plugs.
Their interior metal ball suits food processing where foreign object detection is critical. By prioritizing ease of use, simpleFit® earplugs are a practical solution for workforce safety.

Yes, but
Overprotection is a real risk. Workers wearing gear that attenuates too aggressively lose situational awareness. Donald Elswick, a certified industrial hygienist at Columbia Southern University, documented workers who couldn't hear approaching forklifts because their protection was too much.
The takeaway
Fit testing measures what a specific worker actually receives from a specific device.
Safer. Simpler. Cheaper. One facility Elswick assessed issued three types of hearing protection. After fit testing, they could cover everyone with two.
A difficult truth
Workers who've worn earplugs for 20 years and show clean audiograms are hardest to convince. They feel protected. The hearing loss just hasn't shown up yet.
Elswick's argument: pair fit testing with every audiogram, like an eye exam with a vision prescription.
The gear exists. The will to verify it doesn't.
Protect your workforce's hearing
Occupational hearing loss doesn't announce itself. It builds slowly, stays invisible on audiograms for years, and by the time it shows up, it's permanent.
