En pliant et rivetant les différents parties de la structure des voitures, les marteaux pneumatiques utilisés engendrent bruit et vibration. Le bruit produit par les six marteaux étudiés dans une usine de fabrication de voiture est de type impulsive avec plus de vingt impulses par second. Le niveaux moyen de la pression crête est 131.9dB avec la déviation standard de 2.1dB. Le niveau équivalent pendant une journée de travail est 114 de. La vibration des mains a été aussi évaluée dans les 3 directions (x,y,z). La direction z est la direction principale par laquelle la vibration entre les mains. La valeur efficace moyenne d'accélération est 23.5 m/s2 avec la déviation standard de 15.2 m/s2. Le temps d'exposition total pendant la Journée de tr...
