Risques dus au bruit (RSS)
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...
The hearing capabilities of a worker are very important for communication, gaining situational awareness, and reducing the risk of other hazards or injury. However, understanding communications in extreme noise and at work sites is always challenging while wearing hearing protection. Too much protection and a worker cannot hear and is vulnerable to other safety hazards. Too little protection, and the worker is inadequately protected and at a higher risk for noise-induced hearing loss . For those who seek to bridge the gap between traditional hearing protection and communication, the technology...
Noise induced hearing loss is irreversible damage to the ears caused by exposure to high levels of noise. A recording on HSE site demonstrates how hearing is gradually lost over a working life: « Noise induced hearing loss – Audio demonstration reveals potential effects». You can also 'see' the sort of damage that excessive noise can cause inside your ears; the clip has been reproduced from "The Hearing Video" by the kind permission of WorksafeBC.

But to settle the question more high quality studies are needed. Noise in non-industrial workplaces is an increasing problem. Annoyance and complaints over noise are frequently reported in these workplaces, whereas the risk of hearing damage is usually not the major concern. Could it be a cause of increased sickness absence via a mechanism starting with job dissatisfaction or via health problems caused by the noise exposure? Only 3 epidemiological studies have investigated the effect of occupational noise on sickness absence. In the one study most pertinent to the question, noise was associated...
What factors influence employers' decisions and practices? Three factors were found to influence noise management: (i) managers' own knowledge/awareness of noise risks and associated controls, (ii) the health and safety culture of the company and (iii) its size. Managers generally underestimated the significance of noise as an occupational health risk; a critical knowledge gap was understanding what controls exist and would work in practice. The size of the company influenced the approach taken with smaller companies showing increased likelihood of reduced quality in noise management (ie...
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...
«Les chiffres sont alarmants: les jeunes entendent de moins en moins bien.» De telles affirmations offrent bien évidemment matière à réflexion. Une étude de la Suva (assurance-accidents obligatoire suisse) réalisée dans le cadre de la Journée contre le bruit atteste pourtant le contraire en ce qui concerne les apprentis de l'industrie et de l'artisanat. « Les études étrangères qui montrent une dégradation de l'ouïe chez les jeunes ne sont pas directement transposables à...
Afin d'offrir un appui technique aux décideurs politiques dans leur évaluation des risques du bruit environnemental sur la santé, l'Organisation mondiale de la Santé (OMS) vient de publier un rapport pour lequel ont collaboré étroitement des chercheurs de l'Institut national de santé publique du Québec. Pierre Deshaies et Zilma Gonzales de l'unité Santé au travail de la Direction des risques biologiques et de la santé au travail sont les auteurs du chapitre sur les acouphènes, en collaboration avec...
Bien que le bruit soit le principal facteur de la surdité d'origine professionnelle, certaines substances chimiques peuvent produire des effets ototoxiques qui pourraient rendre l'oreille plus vulnérable à une agression sonore, comparativement au bruit seul. Il s'agit notamment de solvants, d'asphyxiants, de métaux et de pesticides, largement répandus dans les milieux de travail. Au Québec, plus de 400 000 travailleurs sont exposés à des niveaux de bruit élevés, ce qui soulève des inquiétudes quant...
Music-induced hearing loss hether it's rock, classical, hip hop, or something in between, at certain sound levels, repeated exposure to music can cause permanent hearing loss and/or ringing in the ears known as tinnitus. Recent studies by NIOSH researchers and others at nightclubs and other music venues show that all employees studied, regardless of occupation (waiters, bartenders, DJs, etc), were exposed to noise levels above the internationally recommended limits of 82-85 dB(A)/8 hours and were at a higher risk of developing hearing loss and/or tinnitus. A new term, music-induced hearing...
Job-induced hearing loss is a big problem in today's work settings, affecting workers in industry sectors such as manufacturing, construction, mining, transportation, agriculture, and the military. Approximately 22 million workers are exposed on the job to noise levels that could harm their hearing. The National Institute for Occupational Safety and Health (NIOSH) has developed the NIOSH Hearing Loss Simulator, a software training and communication tool that demonstrates the effects of noise exposure on a worker's hearing without exposing the person to harmful noise levels or toxic materials...
La population des travailleurs de l'agglomération toulousaine a été particulièrement touchée par l'explosion de l'usine "AZF" en raison du nombre élevé d'entreprises détruites. À la suite d'une enquête transversale dans cette population, une cohorte de travailleurs (cohorte santé "AZF") a été mise en place. L'objectif est de décrire sur une période de cinq années les conséquences sanitaires et socioprofessionnelles de l'explosion....
This report details the results of a search of the published peer-reviewed literature investigating the relationship between tinnitus (ringing or buzzing in the ears), noise exposure at work and noise-induced hearing loss. A total of 12 citation databases (earliest date 1951) were searched which identified 252 publications, of which 34 were found to be relevant to the review. A number of studies have reported the prevalence of tinnitus in populations exposed to noise at work to be between 87.5% and 5.9%. Factors such as the type of participant (eg health surveillance, compensation claimant), the...
Synthèse systématique avec méta-analyse et méta-régression Synthétiser l'information scientifique disponible concernant les effets de l'exposition au bruit en milieu de travail durant la grossesse. Les effets sur la grossesse étudiés sont : l'avortement spontané (AS), la mortinaissance (MN), les anomalies congénitales (AC), l'accouchement avant terme (AAT), le faible poids à la naissance (FPN), l'insuffisance de poids pour l'âge gestationnel (IPAG), la pré-éclampsie (PE) et l'hypertension...
Noise-induced hearing loss remains one of the most prominent occupational diseases in Europe. However, noise is no longer perceived as the only source of work-related hearing damage and increasing attention is being paid to the risks of combined exposure to high-level noise and ototoxic substances, that is, those which can affect the structures and/or the function of the inner ear and the associated signal transmission pathways in the nervous system. This publication aims to provide an up-to-date picture of our knowledge in this field. It includes: a description of the basic features of the physiological...
