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...
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...
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...
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...
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...
