"La réglementation européenne et belge concernant le bruit demande que chaque entreprise cherche à éviter ou à réduire l'exposition des travailleurs à ce facteur de risque.
Conformément à la stratégie SOBANE de gestion des risques professionnels, cette brochure décrit une méthode à quatre niveaux : dépistage, observation, analyse et expertise qui devrait permettre de mieux prévenir et /ou corriger les risques liés au bruit. La brochure comprend une série de fiches d'aide.
Elle a été rédigée par le professeur Jacques Malchaire, chef de l'unité hygiène et physiologie du travail de l'UCL, qui a coordonné le projet SOBANE cofinancé par le SPF emploi, Travail et Concertation sociale et le Fonds social européen"

"Les protecteurs individuels contre le bruit (PICB) peuvent être utilisés en complément des moyens de prévention collective contre les nuisances sonores. L'atténuation des bruits apportée par ces équipements est mesurée en laboratoire suivant certaines normes. Des méthodes commerciales existent afin d'évaluer l'atténuation fournie par les PICB sur le lieu de travail. L'INRS a étudié la précision de 4 systèmes commerciaux par rapport aux méthodes de référence normalisées. Les résultats montrent que le niveau de protection peut être estimé, pour une personne donnée et un PICB donné, par certains de ces systèmes commerciaux avec, toutefois, quelques incertitudes."

"Background Few assessments have been conducted on the impact of a Train-the-Trainer (T3) approach for training delivery. The present study compared the effectiveness of a noise induced hearing loss (NIHL) prevention training delivered using Train-the-Trainer and expert trainer modalities. Methods Participating construction companies were assigned to the Train-the-Trainer or expert trainer modalities. Workers were recruited from each company and then trained. The effectiveness of the modalities was assessed through the use of surveys. The accuracy of self-reported hearing protection device (HPD) use was also evaluated through on-site observation. Results Post-training scores for hearing conservation knowledge, perceived barriers, and current and intended future use of HPDs improved significantly for both training modalities. Subjects trained by T3 trainers significantly increased their beliefs regarding general susceptibility to NIHL, desire to prevent NIHL, and ability to recognize, and control hazardous noise exposures. The expert-trained groups significantly increased their beliefs regarding the benefits of HPD use and ability to ask for help with HPDs. The only changes that were significantly different between modalities were in general susceptibility to NIHL and effective use of HPDs. However, these beliefs differed significantly between subjects in the two-modality groups prior to training. Self-reported HPD use was poorly correlated with observed use, calling into question the validity of survey-based HPD use measures in this context. Conclusions The training improved beliefs regarding HPD use, increased workers' hearing conservation knowledge, and increased self-reported HPD use. The effectiveness of the training was not found to be dependent on training modality. Am. J. Ind. Med. 51:130-137, 2008. © 2007 Wiley-Liss, Inc. "

"Background Hearing conservation efforts in construction frequently rely on use of hearing protection devices (HPDs): however, training on HPDs is often not provided, and usage rates remain low. In this study, a hearing conservation training program was developed and pilot tested. Methods A theoretical model was selected as the basis for the program, and program contents and delivery methods were selected to optimize the effectiveness and flexibility of the training. Two evaluation measures were selected to assess training-related changes in self-reported HPD use. The first was a validated method using concurrent work-shift noise dosimetry, and the second was a survey concerning workers beliefs and attitudes towards HPDs and HPD use. Results The training program was pilot tested on a single construction site. Complete assessment data were available for 23 workers. The percent of time when hearing protection was used during noise levels above 85 dBA nearly doubled post-training, and the change was statistically significant. Conclusions Pre- and post-training data from participating workers demonstrated that HPD use can be increased significantly with basic model-based training, even in industries with complex noise exposures such as construction.
