What’s So Special About
Custom-Fit Earplugs?
Every workplace is different, and every workplace is exposed to a different level of noise. Employees, therefore, need the right protection to guarantee their safety. It’s here that Rocky Mountain Mobile Hearing Testing can help by providing custom earplugs.
With our mobile service, we can come to your workplace, assess each worker and provide them with custom molded earplugs that perfectly fit their ears, are comfortable and adheres to CSA standards. Your workers will now feel more confident in wearing their custom earplugs, which will be made from high-grade medical silicone, ensuring an extremely comfortable fit.
Our custom-fit earplugs last for up to four years, come with a storage pouch for hygiene and protection, are available with either a permanent cord, detachable cord, or handle, and are a worthwhile and long-term investment. We also provide a 60-day right-fit guarantee to ensure that your workers get correctly-fitting molded earplugs.

Ear Defender Molds
Many people don’t realize that occasional and intermittent noise in the workplace increases the rate of natural hearing degradation. In conditions where noise is persistent or excessive, such as those in construction and industrial environments, those who fail to properly protect their ears run a much higher risk of irreversible hearing damage. Oto’s Ear Defenders provide ultimate protection to those in noise impacted environments.
Sound Attenuation Requirements from CSA Standard Z94.2-94
The minimum attenuation (sound reduction) in decibels at different frequencies is given for each class of hearing protection below. Oto’s Ear Defenders not only meet but exceed all of the standards in each class.
Ear Defenders provide more attenuation than required as per Worker’s Compensation Ratings for Class A, or B hearing Protection.

Do Your Employees Need Custom Molded Ear Plugs?
In order to determine if your employees need custom molded earplugs, an assessment of your workplace must be conducted. Not only can our mobile service provide designs for custom-made earplugs, but we have the tools to survey your facility. As part of our noise measurement service, our team will use the latest equipment to measure sounds and noise levels throughout your workplace. We will sound map the area to determine the dangerous spots. If the levels are extremely high and employees are exposed to dangerous levels, you must provide them with earplugs to guarantee their safety and protection. We can also test your employees with an audiometry test to measure their hearing ability. Audiometric testing noise measurement can provide useful data to help you implement or improve a hearing conservation program.
