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...
Noise-Induced Hearing Loss Among Adults - United States 2011–2012
Introduction: The 2016 National Academies of Sciences report “Hearing Health Care for Adults: Priorities for Improving Access and Affordability” included a call to action for government agencies to strengthen efforts to collect, analyze, and disseminate population-based data on hearing loss in adults. Methods: CDC analyzed the most recent available data collected both by questionnaire and audiometric tests of adult participants aged 20–69 years in the 2011–2012 National Health and Nutrition Examination Survey (NHANES) to determine the presence of audiometric notches indicative...
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...
Occupational noise exposure and noise-induced hearing loss are associated with work-related injuries leading to admission to hospital
Objective: This study focuses on work-related injuries that required admission to hospital in a population of male workers exposed to occupational noise (≥80 dBA) which some displayed a hearing loss due to their exposure. Methods: The study population count 46 550 male workers, 1670 (3.6%) of whom incurred at least one work-related injury requiring admission to hospital within a period of 5 years following hearing tests conducted between 1987 and 2005. The noise exposure and hearing loss-related data were gathered during occupational noise-induced hearing loss (NIHL) screening. The hospital...
Ethylbenzene-Induced Hearing Loss, Neurobehavioral Function, and Neurotransmitter Alterations in Petrochemical Workers
Objective : To estimate hearing loss, neurobehavioral function, and neurotransmitter alteration induced by ethylbenzene in petrochemical workers. Methods : From two petrochemical plants, 246 and 307 workers exposed to both ethylbenzene and noise were recruited—290 workers exposed to noise only from a power station plant and 327 office personnel as control group, respectively. Hearing and neurobehavioral functions were evaluated. Serum neurotransmitters were also determined. Results : The prevalence of hearing loss was much higher in petrochemical groups than that in power station and control...
Prevalence of hearing loss in the United States by industry
Background Twenty-two million workers are exposed to hazardous noise in the United States. The purpose of this study is to estimate the prevalence of hearing loss among U.S. industries. Methods We examined 2000–2008 audiograms for male and female workers ages 18–65, who had higher occupational noise exposures than the general population. Prevalence and adjusted prevalence ratios (PRs) for hearing loss were estimated and compared across industries. Results In our sample, 18% of workers had hearing loss. When compared with the Couriers and Messengers industry sub-sector, workers employed...
Promoting Hearing Health among Fire Fighters
Exposure to high noise levels among fire fighters is well documented and increases the risk for noise-induced hearing loss. NIOSH recommends measures to promote better hearing health through the use of quieter equipment, better work practices, hearing protection devices, and implementation of effective hearing loss prevention programs.

Emotional stress may affect sound perception
A fresh article by researchers including Dan Hasson at Karolinska Institute and the Stress Research Institute in Stockholm, Sweden concludes that emotional exhaustion in women affects their sound perception in a negative way. The sample of subjects were taken from SLOSH (Swedish Longitudinal Occupational Survey of Health) and followed up with additional data collection. After being provoked with an acute stress task women who had scored high on emotional exhaustion also showed a greater sensitivity to sounds. This study supports the theory that hearing problems such as hyperacusis (auditory sensitivity...
Noise-Induced Hearing Loss : Scientific Advances
Exposure to loud noise continues to be the largest cause of hearing loss in the adult population. The problem of NIHL impacts a number of disciplines. US standards for permissible noise exposure were originally published in 1968 and remain largely unchanged today. Indeed, permissible noise exposure for US personnel is significantly greater than that allowed in numerous other countries, including for example, Canada, China, Brazil, Mexico, and the European Union. However, there have been a number of discoveries and advances that have increased our understanding of the mechanisms of NIHL. These advances...
Noise-induced hearing loss
Noise-induced hearing loss (NIHL) still remains a problem in developed countries, despite reduced occupational noise exposure, strict standards for hearing protection and extensive public health awareness campaigns. Therefore NIHL continues to be the focus of noise research activities. This paper summarizes progress achieved recently in our knowledge of NIHL. It includes papers published between the years 2008-2011 (in English), which were identified by a literature search of accessible medical and other relevant databases. A substantial part of this research has been concerned with the risk of...
Centre d’appels : que faire en cas de choc acoustique ?
Conseils de l’INRS pour répondre à l’urgence et prévenir le risque auditif Un choc acoustique expose un téléopérateur via son casque d’écoute à un niveau de bruit élevé. Il peut entraîner des traumatismes. L’INRS propose une procédure à suivre pour traiter ce problème lorsqu’il survient dans un centre d’appel : prise en charge immédiate du téléopérateur exposé, recherche des causes pour corriger le problème à la source...
Work-related noise may contribute to physical and mental health problems in teachers
Empirical research indicates that children and teachers are exposed to mean sound levels between 65 and 87 dB (A) and peak sound levels of 100 dB (A) in schools, which may lead to hearing loss and mental health problems. A questionnaire containing 13 targeted questions about noise and sensitivity to noise was distributed to 43 teachers aged between 25 and 64 years at five different primary schools in the Cologne municipal area. The small number of interrogated teachers leads to a wide range of deviation and little significance in the results. Thus, several results are reported following tendencies...
Working with vibrating machines with noise exposure increases the risk of hearing loss
The aim of this study was to examine the possible association of combined exposure of noise and hand-arm vibration (HAV) and the risk of noise-induced hearing loss. Workers in a heavy engineering industry were part of a dynamic cohort. The results show that working with vibrating machines in an environment with noise exposure increases the risk of hearing loss, supporting an association between exposure to noise and HAV, and the noise-induced hearing loss. Source : Hans Pettersson, Lage Burström, Mats Hagberg, Ronnie Lundström, Tohr Nilsson. Noise and hand-arm vibration exposure in relation...
Workers in the Mining, Manufacturing, and Construction industries need better engineering controls for noise
Twenty-two million workers are exposed to hazardous noise in the United States. 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 showed that 18% of workers had hearing loss. When compared with the Couriers and Messengers industry sub-sector, workers employed in Mining, Wood Product Manufacturing, Construction of Buildings and Real Estate and Rental and Leasing had higher risks for hearing loss. Workers in the...
Hearing, sound fatigue and annoyance highly affected employees at the preschools.
Hearing impairments and tinnitus are being reported in an increasing extent from employees in the preschool. The investigation included 101 employees at 17 preschools in Umeå County, Sweden. Individual noise recordings and stationary recordings in dining rooms and play halls were conducted at two departments per preschool. The effects of noise exposures were carried out through audiometric screenings and by use of questionnaires. The average individual noise exposure was close to 71 dB (A), with individual differences but small differences between the preschools. The noise levels in the dining...
Wireless Communication : Good team communication under difficult and potentially dangerous conditions required
Team communication is absolutely essential in creating a safe, productive and effective work environment. Ambient noise can dramatically affect the clarity of team communications. First responders may be subjected to deafening siren noise while en route to a rescue operation, but they are not alone. Many industries expose workers to high noise levels on the job. Airport ground personnel must contend with the roar of jet engines. Road and construction crews must communicate against a backdrop of heavy equipment. Factory workers must talk over the noise of a manufacturing plant. These seemingly unrelated...
Population in Michigan is exposed to noise levels with possibility of long-term adverse effects on hearing
A total of 73 000 person-hours of noise monitoring were conducted in this observation study. Median overall daily average levels were 79 and 77 dBLeq A,8,equiv , with average levels exceeding EPA recommended levels for 70% of participants. The authors concluded that a large portion of the general population is exposed to noise levels that could result in long-term adverse effects on hearing. Gender and occupation were most strongly related to exposure, though most participants in this study had occupations that are not conventionally considered noisy. Source : Flamme, G.A. et al. Typical noise...
Low-pass filtered masking noise makes speech-in-noise tests more sensitive
An easily accessible screening test can be valuable in the prevention of noise-induced hearing loss (NIHL). The Dutch National Hearing Foundation developed ‘Earcheck’, an internet-based speech-in-noise test, presenting CVC-words in stationary broadband noise. However, its sensitivity to detect NIHL appeared to be low, 51% ( Leensen et al, 2011 , part 1). This study showed that Earcheck with low-pass filtered noise made the best distinction between normal hearing and NIHL, without reducing test reliability. The use of this noise condition improved the sensitivity of Earcheck to 95%....
“Hearing Conservation Programs” are not an adequate substitute for engineering and administrative controls.
Noise induced hearing loss is still too prevalent in American workplaces as the attempts at “hearing conservation programs” have proven inadequate. The author explains that the American workers have been the subjects in what has been largely a failed experiment for 28 years. Hearing protection devices are neither an efficient nor a humane replacement for eliminating the noise hazard and should once again be allotted their proper place in the control hierarchy. Several studies have found widespread and serious gaps in compliance with requirements such as audiometric testing, training...
Occupational diving is associated with hearing loss caused by noise
L’article présente une étude des causes de la perte d’audition chez le plongeur professionnel. Les raisons principales identifiées sont l’exposition au bruit et les accidents barotraumatique. Une perte auditive tant subjective qu'objective a été associée à l'exposition professionnelle au bruit, mais non pas avec la fréquence de plongée ou avec une histoire de barotraumatisme de l'oreille moyenne. La plongée sans incident n’apparait pas être responsable de la baisse d’audition. Source...
According to new research, approximately 20 percent of all Americans over the age of 12 suffer hearing loss in at least one ear
The new study, led by Johns Hopkins researchers and published in the Nov. 14 Archives of Internal Medicine , is thought to be the first to estimate hearing loss on the national scale rather than on specific cities or populations. Using the World Health Organization's definition for hearing loss (not being able to hear sounds of 25 decibels or less in the speech frequencies), the researchers found that overall, about 30 million Americans, or 12.7 percent of the population, had hearing loss in both ears. That number jumped to about 48 million, or 20.3 percent, for people who have hearing loss...
Suisse : succès impressionnant: depuis 1971, le nombre des lésions auditives est passé de 37 à 8 %
En Suisse, environ 200 000 personnes sont exposées, dans le cadre de leur activité professionnelle, à du bruit pouvant mettre en danger l'ouïe. Des stations d'examen mobiles ou audiomobiles se déplacent dans toute la Suisse pour examiner tous les travailleurs exposés au bruit dangereux pour l'ouïe dans le cadre de leur activité professionnelle, par exemple les ouvriers forestiers, les serruriers, les menuisiers, les agents de police et, depuis 1987, les musiciens d'orchestre. Les examens de contrôle réguliers, le conseil...
