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.

Abstract It has been suggested that the association between self-reported occupational noise exposure and vestibular schwannoma (VS), found in several studies, represents recall bias. Therefore, we aimed to study the relationship in a large case-control study using occupational noise measurements. We performed a case-control study using data from Sweden for 1,913 VS cases diagnosed in 1961–2009 and 9,566 age- and sex-matched population controls. We defined occupational history by linkage to national censuses from 1960, 1970, 1980, and 1990. We estimated occupational noise exposure for each case and control using a job-exposure matrix. There was no association between occupational noise exposure and VS. Among subjects assessed as ever exposed to occupational noise levels of ≥85 dB (214 cases and 1,142 controls), the odds ratio for VS per 5 years of exposure was 1.02 (95% confidence interval: 0.90, 1.17). Workers with noise levels of ≥85 dB for at least 15 years (5-year latency period), showed no increased risk of VS (odds ratio = 0.98, 95% confidence interval: 0.73, 1.31) compared with those who had never been exposed to noise levels of 75 dB or higher. In summary, our large study does not support an association between occupational noise exposure and VS.

Occupational Noise Exposure

Abstract Objective Many epidemiological studies have reported an association between occupational noise exposure and hypertension among workers, but have failed to obtain conclusive results. Thus we aimed to assess whether there is a relationship between hypertension and occupational noise. Methods This study adopted a case–control design to verified the relationship of occupational noise and hypertension. This study included 1527 subjects (case group, 509 individuals; control group, 1018 individuals) from a modern automobile manufacturing company. The information includes the general characteristics, occupational factors, and data collected from physical examination, hematology and serology testing. Two-sample t-tests, The Chi-square test, the Ridit analysis method were used for comparing variables. A non-conditional logistic regression model was used for multivariate analysis based on single factor analysis. Results Toxin exposure was found to be a risk factor for the occurrence of hypertension in workers who were exposed to noise in modern enterprises (OR=3.45).Heart rate was significantly different between the case and control groups (OR=5.98). Occupational noise exposure is a risk factor for hypertension, and the risk of hypertension for people exposed to noise intensity ≥80 dB is 2.23 times (95% CI 1.62–3.06) higher than that for people exposed to noise intensity <80 dB. Conclusions Occupational noise exposure is an independent risk factor for hypertension. it can be used to direct the new criteria of noise exposure limit to protect worker’s health.

Hearing thresholds and distortion product otoacoustic emissions were measured for teachers of vocal performance who were gathered for a national conference. Results showed mean audiometric thresholds to be consistent with noise induced hearing loss, more than what would be expected with normal aging. Years of instruction and age were considered as factors in the hearing loss observed. It was concluded that hearing conservation should be initiated with this group to help raise awareness and protect them from hearing loss due to occupational noise exposure.
