Résumé

Pour mesurer simultanément l'intensite du niveau sonore ambiant et de celui qui est transmis a travers un casque antibruit, on a utilise deux dosimetres modifies. La difference entre les deux mesures représentait l'indice d'atténuation. On a applique cette methode dans la présente etude sur l'effet des cheveux, des lunettes ou d'un chapeau sur l'efficacite des casques antibruit. On a constate que meme si les cheveux, les lunettes ou un chapeau mince réduisaient effectivement l'atténuation du niveau sonore, cette baisse ne dépassait generalement pas 5 dB. Cependant, le port d'un chapeau épais entraînait, dans la plupart des cas, une reduction de plus de 10 dB. Les conclusions de 1'etude favorisent l'idee de procéder a l'ajustement des casques antibruit.
