Discover the new generation of COTRAL moulded hearing protections

As you are aware, noise and deafness are major risks on an occupational level.

In France, 1 of every 3 employees is exposed to harmful noises on a daily basis.

7% of the employees are subject to noises exceeding 85 dB(A) for more than 20h/week.

Maintaining and controlling efficacy of the protections

Hygiene and maintenance of your COTRAL hearing protections

Maintenance of the customised hearing protections is essential in order to ensure their optimum use 100% of the time spent exposed to noise and efficacy of the acoustic filter.

Ensuring efficacy of the acoustic filter

Daily wear of the hearing protections results in soiling: dust, wax deposits... These substances accumulate on the protection, but particularly in the canal and filter.

Regularly maintaining your hearing protections means ensuring comfort in use, but also maintaining the efficacy of the acoustic filter by avoiding excessive insulation and allowing communication.
