| Descripción: |
Three groups of 15 industrial workers were identified according to their pattern of exposure to noise: (a) steady-state, (b) periodically fluctuating and (c) randomly variable. A personal dosimeter was worn by each worker for three consecutive days. The long term exposure was also assessed by means of sound level meter sampling procedure. The standard error of measurement of the dosimetry was ±1.10, ±1.56 and ±2.86 dB for the three types of exposures respectively. Dosimetric and SLM data achieved the same result within 0.5 dB for the first 2 groups. An average difference of 3.4 dB was obtained with the third group Trois groupes de 15 travailleurs industriels ont été recrutés en fonction de la configuration temporelle de leur exposition professionnelle au bruit. Il s'agissait a) de bruits stables, b) de bruits dont le niveau subit des variations périodiques et c) de bruits dont îe niveau varie de manière aléatoire. Chaque travailleur a porté un dosimètre individuel durant trois jours consécutifs. L'exposition à long terme a également été évaluée par échantillonnage sonométrique. L'erreur-type de mesure dosiméirique atteignait respectivement ± 1.10, ± 1.56 et ± 2.86 dB pour les trois types d’exposition. Les mesures dosimétriques et sonométriques ont donné le même résultat à 0.5 dB près pour les deux premiers types d'exposition. Un écart moyen de 3.4 dB, en faveur des mesures sonométriques, a été obtenu pour le groupe de travailleurs dont l'exposition était aléatoire. |
