Custom Hearing Protectors for the well-being of your workers

These custom hearing protectors device outperform all other devices on the market. They enable interpersonal communication and are comfortable, convenient and cost-effective. These are the most sought-after hearing protectors worldwide.

How do we create such a comfortable hearing protector ?

Custom hearing protectors 3D scanning process

Our manufacturing process works as follows :

  • We take an impression, or mold, of the ear canals of every employee
  • The mould is 3D scanned to create a computerised image
  • The computerised image is modelled into the smallest, lightest and most comfortable hearing protector possible

This comprehensive process ensures that each hearing protector device fits perfectly, with 100-micron precision (the width of a strand of hair). They are so comfortable that they can be worn all day.

Protected, but not isolated

The hearing protector is personalised for each employee by our filter selection process : SAPAN® considers the noise level, level of perception, and the unique requirements of each employee.

Qeos offers two ranges of filters, each providing a different level of attenuation

Maintaining your custom hearing protectors is simple

Primo Optimum kit

Your hearing protectors need daily cleaning, and we've made this as quick and easy as possible

  • By using Cleanil effervescent solution, you can be sure that your protection is perfectly clean, and that you are maintaining the effectiveness of the acoustic filter.
  • Our custom hearing protectors have handles (both with and without a cord) which ensure that you never need to touch the actual ear plug, no matter how dirty your hands are.
  • Our ear plug material, Crylit, is non-porous so it never absorbs dirt and can be quickly and easily cleaned with our Cleanil wipes.

With or without a handle, and with or without a cord, Cotral Lab Custom Hearing Devices adapt to your employees’ needs, at their workstations.

Cotral Lab hearing protectors are Food Processing Industry compliant. A fully detectable electro-magnetic ball and cord are offered.

Conveniently manage your hearing protectors online

Your personal and secured online access to the customer area of Cotral Lab’s website makes it easy to manage your devices in one central location. You can also place orders and facilitate implementation of solutions from the very beginning.

The ear molds, once taken on-site, within the timeframe you decide, are digitally stored on our servers. This saves you time in cases where remanufacturing is required.
