What’s So Special About
Custom-Fit Earplugs?
No workplace is the same, and each one is regularly exposed to varying levels of noise, and employees at any worksite require proper protection for safety. Rocky Mountain Mobile Hearing Testing aims to provide the correct noise exposure protection with custom earplugs.
Our mobile services will come to your workplace, thoroughly assess individual employees, and offer them custom moulded earplugs that perfectly fit each ear. These custom earplugs should sit comfortably in the ear and will adhere to CSA standards. Employees working in high noise exposure environments can effectively protect their hearing with custom earplugs made from high-grade medical silicone for the best and most comfortable fit possible.
The custom-fit earplugs we offer employees can last for four years without deterioration that also comes with a storage pouch for protection and hygienic purposes. These custom-fit earplugs are also provided with a detachable cord, permanent cord, or a handle, all worthwhile investments for anyone requiring a custom-fit earplug. Additionally, a 60-day right-fit guarantee is offered with earplugs, where you can ensure all employees get earplugs that are moulded to the ear.

Ear Defender Molds
To comply with OHS standards and protect your employees, you must provide them with custom earplugs. With our custom-designed earplugs for every one of your employees, you take proper preventative measures to protect their hearing. We will provide your employees with custom-designed earplugs after we visit your workplace, take impressions of the individual employee’s ear, and return the resulting earpiece to the designated workplace.
When we perform these protective measures, we can assure you that these services will be efficient as we test each employee and can be scheduled at a time that is most convenient for everyone. Whenever you require our assistance, our mobile facilities will be at your disposal. Our tests are conducted in our mobile facilities at workplaces located in cities in Alberta that include Calgary, Red Deer, and Lethbridge, in addition to Saskatchewan and Eastern BC.
