A hearing protection to meet your needs

Choose personalisable hearing protections

More than mere moulded hearing protections, COTRAL Laboratory propose personalisation of your anti-noise protections to suit each of your employees.

A hearing protection personalisable to each person's post and profession

The COTRAL customized hearing protections are adapted to each employee's profession and post.

1. They are available in two materials: silicone and Crylit^® (a hard material specifically designed for digital manufacture of the COTRAL anti-noise protections).
2. The anti-noise protections are transparent or blue for the food processing industry.
3. Two types of COTRAL hearing protection, with a hook and without a hook, exist. The hearing protection with a hook ensures a good hold in the ear owing to its double locking whereas the hearing protection without a hook is easier to insert and more discreet.
4. With 17 acoustic filters available throughout the entire range, the attenuation capacity extends from 15 to 32 dB.

These many options allow us to offer you a moulded hearing protection for each type of post, each user and the particularities of each profession.

Let us establish together each user's hearing protection

Using the ATAG+ method, your COTRAL prevention technician will determine the needs of each of your employees in conjunction with you and in accordance with your schedule of conditions.

Determining the model of anti-noise hearing protection with the most suitable filter for each individual is a joint process.
