“…The statistical association shown here between occupational noise and work accidents has also been identified by other authors 9,10,11,12,13,14 , which speaks in favor of the existence of a causal relationship between these two variables. However, it is important to note that noisy environments can (and usually do) contain other occupational risks for accidents besides noise per se.…”

“…Added to the above-mentioned auditory and non-auditory pathophysiological alterations, the specialized literature indicates that workers exposed to intense occupational noise present a two-to fourfold risk of accidents as compared to unexposed workers 9,10,11,12,13,14,15 . Thus, noisecontrol and hearing conservation programs aim both to prevent exposure and hearing loss as well as to reduce the risk of work accidents 11,16 .…”

Noise is the most frequent type of occupational exposure and can lead to both auditory and extra-auditory dysfunction as well as increasing the risk of work accidents. The purpose of this study was to estimate the attributable fraction of work accidents related to occupational noise exposure in a medium-sized city in Southeast Brazil. In this hospital-based case-control study, including 600 cases and 822 controls, the odds ratio of work accidents (controlled for several covariables) was obtained classifying occupational noise exposure into four levels and determining the prevalence at each level. Based on these data, the calculated attributable fraction was 0.3041 (95%CI: 0.2341-0.3676), i.e., 30% of work accidents in the study area were statistically associated with occupational noise exposure. The authors discuss the causes of this association and the implications for the prevention of work accidents.

“…Noise has been shown to be a general and nonspecific stressor (18)(19)(20) that includes a host of psychological (18,21,22) and physiological (23)(24)(25)(26) response s. Nevertheles s some evidence indicates that there are workers who are more susceptible to noise stress than others. These workers can apparently be identified by their reports of noise annoyance.…”

“…These workers can apparently be identified by their reports of noise annoyance. Noise annoyance refers to subjective ratings of the noise as undesirable, irritating, and disturbing (22,27). Noise annoyance has been found to be independent of the ambient noise level (6,18,28), but it is related to subjective noise sensitivity (27,29).…”

Green, MD1.2 MELAMED S, RABINOWITZ S, GREEN MS. Noise exposure, noise annoyance, use of hearing protection devices and distress among blue-collar workers. Scand J Work Environ Health 1994;20: 294-300.OBJECTIVES -This study tested the hypotheses that, in high noise levels [~85 dB(A)], hearing protection devices are used largely by workers sensitive to noise, as reflected by reports of noise annoyance, and that the usage would reduce distress symptoms. METHODS -Data collected from 1587 healthy male blue-collar workers included noise exposure level, noise annoyance, use of hearing protection devices, distress symptoms (somatic complaints and poststress irritability), and possible confounding by age, education and ethnic origin. RESULTS -Multiple logistic regression results indicated that the use of hearing protection devices was related to noise exposure level [odds ratio (OR) 2.94, 95% confidence interval (95% CI) 2.58-3.30], but more so to high noise annoyance (OR 3.03, 95% CI 2.77-3.29), even after control for age, education, and ethnic origin. No interaction was found between noise level and noise annoyance. These findings highlight the contribution of noise annoyance to the use of hearing protection devices. Of the 42.6% of workers using hearing protection devices in the presence of high ambient noise, 60% were highly annoyed. Noise-annoyed workers also tended to wear hearing protection devices even in low noise levels. The use of hearing protection devices was associated with lower distress symptoms among the low and moderately annoyed workers, but among the highly annoyed workers the reverse was true. CONCLUSIONS -Thus, for the highly annoyed workers, the use of hearing protection devices was perhaps an additional source of stress. One immediate implication of this study is that future intervention procedures should focus on unannoyed workers who tend to use hearing protection devices less.

ObjectiveTo assess whether exposure to occupational noise is an important risk factor for work-related injuries. Methods A population-based case-control study was performed. Data collection was carried out from May 16, 2002 to October 15, 2002 in the city of Botucatu, southeast Brazil. Cases were defined as workers who had suffered typical work-related injuries in a 90-day period previously to the study, and who identified through systematic random sampling of their households. Controls were non-injured workers randomly sampled from the same population, matched on 3:1 ratio according to sex, age group and census track. A multiple logistic regression model was adjusted, where the independent variable was exposure to occupational noise, controlled for covariates of interest. Results A total of 94 cases and 282 controls were analyzed. An adjusted multiple regression model showed that "work always exposed to high-level noise" and "work sometimes exposed to high-level noise" were associated to a relative risk for work-related injuries of about 5.0 (95% CI: 2.8-8.7; p<0.001) and 3.7 (95% CI: 1.8-7.4; p=0.0003) respectively, when work not exposed to noise was taken as a reference, controlled for several covariates. Conclusions Based on the study findings, investing in hearing conservation programs, particularly those for controlling noise emission at its source, is justifiable aiming at both hearing health maintenance and reduction of work-related injuries.
