Développement d’une antenne microphonique intégrant un système optique pour identifier la position des sources sonores les plus bruyantes en milieu industriel
Dans un contexte industriel, le bruit émis par des machines peut nuire à la santé des travailleurs et générer des problèmes de surdité ou de pertes auditives. Pour pallier ces problèmes, des solutions acoustiques efficaces doivent être mises en place en amont. La première étape d'une étude acoustique de réduction de bruit consiste à localiser la position des sources et à hiérarchiser leurs contributions. Dans un environnement industriel, les travailleurs sont répartis autour...
Control of noise risk in the printing industry
Machinery used in the printing industry is inherently noisy. Noise levels in this industry have the potential to cause work-related hearing damage, if the risks are not properly assessed and managed. HSE has undertaken a study of noise levels and exposures in the printing industry, to determine noise risks and identify control measures. The noise levels measured in this study indicate that print workers are exposed to hazardous levels of noise: 93% of the study population had noise exposure estimates exceeding the lower exposure action value (LEP,d 80 dB) specified in the Control of Noise at Work...
Noise risk as described in instructions supplied with printing machinery
The printing industry uses a wide range of noisy machines that have the potential to damage workers' hearing if the risks are not effectively managed. Users need information that represents noise emissions during the intended uses of the machine, to enable an assessment and the management of the associated noise risks. There is a legal requirement under the Supply of Machinery (Safety) Regulations 2008 for machinery manufacturers to provide declared noise emissions in instruction manuals. (This legislation implements the EU Machinery Directive 2006/42/EC). However, there is a lack of information...
Dose - response relationship between noise exposure and the risk of occupational injury
Many workers worldwide experience fatality and disability caused by occupational injuries. This study examined the relationship between noise exposure and occupational injuries at factories in Korea. A total of 1790 factories located in northern Gyeonggi Province, Korea was evaluated. The time-weighted average levels of dust and noise exposure were taken from Workplace Exposure Assessment data. Apart occupational injuries, sports events, traffic accidents, and other accidents occurring outside workplaces were excluded. The incidences of occupational injury in each factory were calculated by data...
Quantitative neurosensory findings, symptoms and signs in young vibration exposed workers
Background: Long-term exposure to hand-held vibrating tools may cause the hand arm vibration syndrome (HAVS) including vibration induced white fingers and sensorineural symptoms. The aim was to study early neurosensory effects by quantitative vibrotactile and monofilament tests in young workers with hand-held vibration exposure. Methods: This cross-sectional study consisted of 142 young, male machine shop and construction workers with hand-held exposure to vibrating tools. They were compared with 41 non-vibration exposed subjects of the same age-group. All participants passed a structured interview...
Effect of noise and redundant auditory alarm signal on semiconductor production operators' response to machine downtime
This paper investigates the effect of noise and the effect of a redundant impulsive auditory alarm signal on production operators' response to machine downtime in a semiconductor manufacturing system. Machine uptime is essential for productive and efficient production system and therefore downtime calls for an immediate response. Given a higher machine-to-man ratio, there is a difficulty in achieving quick response to machine downtime. For this end, ergonomic tower lamps with visual and auditory displays are used in most semiconductor manufacturing system to alert production operators and therefore...
Mining, Manufacturing, and Construction industries need better engineering controls for noise
The purpose of this study is to estimate the prevalence of hearing loss among U.S. industries. 2000–2008 audiograms for male and female workers ages 18–65, who had higher occupational noise exposures than the general population, were examined. Prevalence and adjusted prevalence ratios (PRs) for hearing loss were estimated and compared across industries. In our sample, 18% of workers had hearing loss. Workers in the Mining, Manufacturing, and Construction industries need better engineering controls for noise and stronger hearing conservation strategies. More hearing loss research is...
Six-degrees-of-freedom measurement to select operator seats based on industry specific field vibration characteristics
The purpose of this paper was to quantify in (6DOF) whole-body vibrations during the daily operating tasks of 5 commonly used mobile machines types used in the steel making and metal smelting industries. Elevated values were observed at the chassis for crest factors, peak running root mean squared accelerations, and vibration total values, resulting in ISO 2631-1 (1997) comfort predictions ranging from Uncomfortable to Extremely Uncomfortable. Vibration dominant frequencies were generally between 1 and 8Hz. A second peak which occurred at approximately 27 Hz was observed for each vehicle in almost...
The assessment of the occupational noise exposure can be improved with the correct measurement strategies
This paper aims at analysing the impact resulting from the adoption of different strategies for assessing workers’ occupational noise exposure. Noise exposure assessment was made using the three strategies proposed in ISO 9612:2009, and computing the corresponding daily exposure level and associated uncertainty. The results obtained showed that the strategies recommended by that standard for each specific case represented the lowest time-consuming ones. The present work is a contribution towards improving the measurement procedure for the assessment of occupational daily noise exposure. The...
Cardiovascular Risk in Rotogravure Industry
Objective: To verify whether the occupational hazards in the rotogravure industry can be associated with cardiovascular effects. Methods: We evaluated cardiovascular parameters and audiometric tests and analyzed noise, solvents, and shift work in 44 exposed and 44 unexposed workers. Results: Unlike unexposed workers, the rotogravure workers showed significant increase of mean systolic and diastolic blood pressure (BP) values (P = 0.019; P = 0.003), higher frequency of hypertension (P = 0.002) and electrocardiographic abnormalities (P = 0.0001), significant reduction or no variation of BP response...
Improvements in education, technical support, and regulatory enforcement reduce barriers to implementation of engineered noise control
The most effective intervention—engineered noise controls (ENC) —is rarely implemented; a qualitative study was designed to investigate barriers to the implementation of ENC. Many factors emerged as possible barriers to the implementation of engineered noise control, including: poor knowledge of relevant regulations, noise reduction options and the health impacts of noise; weak technical skills and experience; low ranking of noise as a hazard by stakeholders; issues around job insecurity, weak language skills; lack of ‘quiet’ machine options and information from equipment...
Une enquête française révèle que 39 % des travailleurs sont gênés par le bruit au travail
Le bruit au travail augmente de 24 % le risque d'accident avec arrêt de travail . Les ouvriers (57 % d’entre eux) et les personnes travaillant sur les chantiers (71%) sont incommodés par le bruit. De plus, 36 % des employés et 28 % des cadres supérieurs et professions intermédiaires souffrent des nuisances sonores. L’environnement de travail a aussi son importance : 51 % des travailleurs en aire ouverte ou centre d’appels, 47 % des salariés des ateliers de production et 18 % des personnes présentes dans un restaurant d'entreprise...

Votre point de vue nous importe, aussi n'hésitez pas à nous...
A Multidisciplinary Study of Factors Influencing Hazard Reduction Strategies, Using Noise Exposure and Hearing Loss as a Model
Noise exposure is a serious problem in many B.C. workplaces. Although workplaces have hearing conservation programs in place as required by law, these programs often fail to include engineered noise controls (ENCs) to the extent they could. ENCs reduce the noise exposure of workers by stopping noise at the source, and are an effective way to prevent occupational-related hearing loss. This study explored barriers to the use of ENCs, through interviews with staff and audits of hearing conservation programs at eight BC workplaces in the food and beverage manufacturing sector.
