Hearing protection: your solution against occupational noise-induced hearing loss (ONIHL)

Protecting your workforce's hearing is essential, and helping you achieve this is our objective and our mission. In order to reach this goal, you must take a comprehensive approach that includes raising awareness, providing effective hearing protectors, and validating its effectiveness.

The hearing protection device: an important choice and a legal requirement.

Any employees exposed to 85+ dB during an eight-hour day must be provided with hearing protectors. This is a key point in your Hearing Conservation Program.

A solution against ONIHL that results in zero occupational deafness.

Cotral Lab helps you implement the most effective hearing protection program by organizing it into five steps. This comprehensive solution is simple to implement, operationally effective, and cost-effective.

The best hearing solution against ONIHL

In order to achieve maximum effectiveness, a hearing protection device has to be worn 100 percent of the time, any time noise is present. With the Cotral Lab solution, you enjoy the following benefits:

  • Comfort: Every custom earplug is 3D-manufactured from molds of each individual’s ear canal to assure a perfect fit and an incomparable level of comfort.
  • Communication: Seven High Frequency Attenuation (HFA) or Uniform Response (UR) type filters allow workers to communicate and remain fully protected.
  • Convenience: Handles, cord, and case prevent loss of the device and make it easy to use and carry.
  • Clean: Good hygiene and reduction of the waste produced by disposable earplugs are among Cotral Lab’s main goals.
  • Cost-effectiveness: All custom hearing devices are backed by a six-year guarantee and have a longer life span.
