Nuisances sonores
Trop souvent, le bruit reste le parent pauvre de la prévention. Soit il est ignoré, soit il ne fait l'objet que d'une protection individuelle à travers les casques et bouchons d'oreilles. Pourtant, ce risque aux conséquences diverses, de la gêne, source de mal-être, à la lésion irréversible, en fonction de sa puissance, peut être traité facilement. Trois millions de salariés exposés. Près de six actifs sur dix qui se disent gênés sur leur lieu de travail, tous secteurs confondus...
Occupational Noise-Induced Hearing Loss
Occupational hearing loss is preventable through a hierarchy of controls, which prioritize the use of engineering controls over administrative controls and personal protective equipment. The occupational and environmental medicine (OEM) physician plays a critical role in the prevention of occupational noise-induced hearing loss (NIHL).

Preventing Hearing Loss Caused by Chemical (Ototoxicity) and Noise Exposure
Millions of workers are exposed to noise in the workplace every day and when uncontrolled, noise exposure may cause permanent hearing loss. Research demonstrates exposure to certain chemicals, called ototoxicants, may cause hearing loss or balance problems, regardless of noise exposure. Substances including certain pesticides, solvents, and pharmaceuticals that contain ototoxicants can negatively affect how the ear functions, causing hearing loss, and/or affect balance. The risk of hearing loss is increased when workers are exposed to these chemicals while working around elevated noise levels....

Noise Exposure Among Federal Wildland Fire Fighters
Hearing loss is one of the most common work-related illnesses in the United States. NIOSH estimates that 22 million U.S. workers encounter noise exposures loud enough to be hazardous. Wildland fire fighting (vs. urban/ structural fire fighting), aims to suppress grass, brush, or forest fires. Wildland fire fighting is considered a high-risk emergency response occupation requiring considerable physical and psychological demands. Wildland fire fighters often work 12 to more than 16 hours per shift for up to 14 consecutive days over a 3- to 9-month period. Source: https://blogs.cdc.gov/niosh...

Use of moulded hearing protectors by child care workers
An interventional pilot study Background: Employees of a multi-site institution for children and adolescents started to wear moulded hearing protectors (MHPs) during working hours, as they were suffering from a high level of noise exposure. It was agreed with the institutional physician and the German Institution for Statutory Accident Insurance and Prevention in the Health and Welfare Services (BGW) that this presented an opportunity to perform a scientific study to investigate potential beneficial effects on risk of burnout and subjective noise exposure at work when child care workers wear MHPs...
Maternal Occupational Exposure to Noise during Pregnancy and Hearing Dysfunction in Children
A Nationwide Prospective Cohort Study in Sweden Background: Many women of childbearing age are occupationally active, which leads to a large number of pregnancies potentially exposed to occupational exposures. Occupational noise has been identified as a risk factor for hearing impairment in adults. However, very few studies have assessed the effect of occupational noise on the fetus. Objectives: The aim of this study was to investigate whether occupational exposure to noise during pregnancy is associated with hearing dysfunction in children. Methods: This population based cohort study included...

Special Issue on Workplace Noise and Vibration
Noise and vibration in the workplace have been known health hazards for many, many years and most countries have had regulations or guidance material for decades. However, sadly, we have not yet succeeded in defeating these problems. The WHO estimates that over 360 million people in the world live with disabling hearing loss with about 16% being due to noise. In Australia the latest NIHL claims data from Safe Work Australia (SWA) show a significant downward trend from 2012. Unfortunately, on closer investigation, nearly all the reduction was due to NSW where there had been a change in the eligibility...
Hearing Impairment Among Noise-Exposed Workers - United States, 2003–2012
Hearing loss is the third most common chronic physical condition in the United States, and is more prevalent than diabetes or cancer. Occupational hearing loss, primarily caused by high noise exposure, is the most common U.S. work-related illness. Approximately 22 million U.S. workers are exposed to hazardous occupational noise. CDC compared the prevalence of hearing impairment within nine U.S. industry sectors using 1,413,789 noise-exposed worker audiograms from CDC's National Institute for Occupational Safety and Health (NIOSH) Occupational Hearing Loss Surveillance Project. CDC estimated...
Hearing Loss and Noise Exposure Among Commercial Fishermen in the Gulf Coast
Objective: Noise is a hazard in commercial fishing. This cross-sectional study associates occupational noise exposure with hearing loss in commercial fishermen. Methods: A comprehensive survey and audiometric testing were administered to 227 participants in the Gulf Coast. Sound-level measurements were obtained aboard a sample of fishing vessels. Criteria specific for hearing impairment (HI) and noise-induced hearing loss (NIHL) were applied to each audiogram. Results: The majority of these fishermen work shifts more than 16 hours for an extended duration. Hazardous noise levels were measured in...
Ototoxic chemicals
Chemicals that result in hearing loss It is well documented that occupational noise exposure is a significant health hazard that leads to permanent noise-induced hearing loss (NIHL) and we have the National Exposure Standard for Occupational Noise to deal with this. It is less well known that a substantial number of medications and common industrial chemicals can also cause hearing loss themselves or exacerbate the effects of noise. These chemicals are said to be ototoxic (oto = ear, toxic = poisonous). They may damage the cochlea in the inner ear and/or the auditory neurological pathways leading...
Hearing difficulty and tinnitus among U.S. workers and non-workers in 2007
Background: Hearing loss and tinnitus are two potentially debilitating physical conditions affecting many people in the United States. The purpose of this study was to estimate the prevalence of hearing difficulty, tinnitus, and their co-occurrence within U.S. populations. Methods: Data from the 2007 National Health Interview Survey (NHIS) were examined. Weighted prevalence and adjusted prevalence ratios for self-reported hearing difficulty, tinnitus, and their co-occurrence were estimated and compared by demographic, among workers with and without occupational noise exposure, and across industries...
The effects of noise on key workplace skills
This study explored the effect on memory and psychomotor performance of wideband noise (simulated in-cabin aircraft noise) at 75 dBA, which is similar to that experienced during the cruise phase of a commercial flight. The results from the tests were compared to the effects of a widely known and common metric on the same skills, namely, blood alcohol concentration (BAC). All 32 participants, half non-native English speakers, completed three different tests (recognition memory, working memory, and reaction time) presented in counterbalanced order, either in the presence of noise, with or without...
