Burden of disease from road traffic and railway noise
A quantification of healthy life years lost in Sweden This paper provides the first estimation of the health burden in terms of disability-adjusted life-years (DALY) of noise from the transport sector in Sweden. Assessments of health impacts of noise on a national level are still rare, but provide valuable tools for policymakers in order to prevent and abate environmental noise exposure.

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...
Association Between Farm Machinery Operation and Low Back Disorder in Farmers
A Retrospective Cohort Study Objective: The association between whole body vibration (WBV) as measured by annual accumulated use of all-terrain vehicles (ATV)/combine/tractor operation and low back disorders (LBDs) among farmers was investigated. Methods: Saskatchewan Farm Injury Cohort Study data was used. Baseline data were collected in 2007 on the three vehicle types and other factors. Follow-up data on LBD symptoms were collected during 2013 resulting in 1149 samples. Results: Adjusted for age, education, and gender, LBDs were associated with tractor operation for 1 to 150 hours/year (Relative...
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...
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...
Open-plan office noise: The susceptibility and suitability of different cognitive tasks for work in the presence of irrelevant speech
The aim of the present study was to test which tasks are suitable for work in open-plan offices according to how susceptible they are to disruption produced by the mere presence of irrelevant speech. The tasks were chosen to tap fundamental capacities of office work involving: search for relevant information, remembering material, counting, and generation of words. The hypothesis was that tasks requiring semantic processing should be impaired by irrelevant speech. To determine the magnitude of performance decrease, two sound conditions (quiet, irrelevant speech) were compared. The results showed...
Vibration and mechanical shock exposure strongly associated with prevalence of neck pain
The objective of this study was to determine whether whole-body vibration (WBV) and mechanical shock exposure from quad bike use are associated with the prevalence of neck and low back pain (LBP) in New Zealand farmers and rural workers. Physical exposures (mechanical shocks), employee status, and low levels of workplace satisfaction are all significantly associated with the 12-month prevalence of LBP in this rural workforce that regularly uses quad bikes. Both vibration and mechanical shock exposure were strongly associated with 12-month prevalence of neck pain. The 7-day prevalence of neck pain...
Effects of hospital noise on staff: Increased stress, annoyance and burnout, but what about job performance?
Hospitals are often noisy and not conducive to staff performance. Indeed, many staff believe that noise negatively affects their professional performance, quality of work, and ability to concentrate and communicate. Research shows that increased stress and annoyance, increased rates of burnout, and reduced occupational health are a few of the possible effects of hospital noise on staff. However, only a few hospital studies have directly linked noise to job performance. Results show that noise and distractions can potentially deteriorate mental efficiency and short-term memory and increase errors...
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...
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...
Professional driving and prolapsed lumbar intervertebral disc diagnosed by magnetic resonance imaging
Objectives The aim of this study was to investigate whether whole-body vibration (WBV) is associated with prolapsed lumbar intervertebral disc (PID) and nerve root entrapment among patients with low-back pain (LBP) undergoing magnetic resonance imaging (MRI). Methods A consecutive series of patients referred for lumbar MRI because of LBP were compared with controls X-rayed for other reasons. Subjects were questioned about occupational activities loading the spine, psychosocial factors, driving, personal characteristics, mental health, and certain beliefs about LBP. Exposure to WBV was assessed...
New comprehensive OSHA Web page on preventing work-related hearing loss contains a wealth of information to help businesses and workers
OSHA launched a new Safety and Health Topics page on Occupational Noise Exposure to provide resources to prevent noise-related hearing loss, which has been listed as one of the most prevalent occupational health concerns in the United States for more than 25 years. Approximately 30 million people in the United States are occupationally exposed to hazardous noise and thousands of workers every year suffer from preventable hearing loss due to high workplace noise levels. The new Web page provides information on the health effects of hazardous noise exposure and comprehensive information on controls...
Driving an unloaded bucket resulted in significantly higher levels of vibration exposure than with a loaded bucket.
Although it is not possible to conclude that high levels of WBV exposure were the only cause of the reported neck and back discomfort, vibration levels experienced by the underground mining load-haul-dump ( LHD) operators indicated health risks were likely to develop, with a higher probability of injury to the back. Analysis of all operators’ injury profiles and their vibration profiles will be important in future studies in order to determine whether these variables are related. The mining industry will need to consider a number of different intervention strategies to have an impact on injury...
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...
Bruit et vibrations, une combinaison dangereuse.
La perte auditive des travailleurs atteints des «doigts blancs» est plus marquée que celle de ceux non atteints. L'exposition au bruit et la durée de l'exposition sont associées à l'acquisition de la surdité. La présence des doigts blancs augmente le risque d'une augmentation de la perte auditive. Cette étude auprès de travailleurs forestiers montre des différences significatives à 500 et 1000 Hz. Source : Le bruit et les vibrations: une combinaison dangereuse. A. Turcot, S.-A. Girard et al.

Whole-body vibration and ergonomics of driving occupations
Back disorders are the most common form of ill health at work. The exact cause of back pain is often unclear but back pain is more common in jobs that involve driving, especially over long distances or over rough ground. Driving exposes the vehicle's occupants to whole-body vibration, that may include the shocks and jolts that are believed to increase the likelihood of injury or pain in the lower back.
