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

Protecting the hearing of your workforce is essential, and helping you achieve it is our objective and our mission. In order to reach this goal, we take a comprehensive approach that includes raising awareness, providing effective custom earplugs, and validating there effectiveness.

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

Any employees exposed to 80+ dB(A) during an eight-hour work day must be provided with hearing protectors. This is a key step 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 easy to implement and cost-effective.

The best solution against ONIHL

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

  • Comfort: Every custom earplug is 3D-manufactured from moulds of each individual’s ear canal to ensure a perfect fit and an incomparable level of comfort.
  • Communication: Choose from seven High Frequency Attenuation (HFA) or three Uniform Response (UR) type filters, which allow workers to communicate while remaining fully protected.
  • Convenience: Handles, cord, and case prevent loss of the ear plugs and make them easy to use and carry.
  • Cleanliness: Good hygiene and reduction of the waste produced by disposable earplugs are among Cotral Lab's main goals.
  • Cost-effectiveness: Cotral Lab's custom moulded earplugs are backed by a six-year guarantee and have an even longer life span.
