Informations techniques

CASQUES ANTIBRUIT ET BOUCHONS D'OREILLES

  • COMMENT BIEN SE PROTÉGER ?

    Choisir l’appareil de protection antibruit adapte.

    • Identifi er la nature du bruit : stable, fl uctuant, intermittent, impulsif.

    • Caractériser le bruit au poste de travail : intensite (dB) et hauteur (Hz).

    • Calculer l’atténuation nécessaire pour revenir à un niveau ambiant acceptable (80-85 dB).

    • Déterminer la durée d’exposition.

      Le bon casque antibruit est celui qui laisse passer les bruits de voix (intensite faible) et qui amenent les bruits insupportables a une echelle plus raisonnable (compris entre 75 et 85 dB).
      Le bruit sur le lieu de travail peut etre mesure et la valeur SNR (Standard Noise Reduction : indice global d’affaiblissement) utilisee comme un element de selection simple.
