Prevalence of noise-induced hearing loss in drivers

Background: Adverse short-term and long-term health effects following a high level of noise have been established. The current study aims to find the relationship of these effects with an environment-specific level of noise exposure. Materials and Methods: A comparative cross-sectional study was conducted among 50 auto-rickshaw drivers and 51 age-matched service-sector employees. The peak average noise exposure in decibels (dB) was measured. The duration of exposure and response regarding perceptions following noise exposure was assessed through a pre-designed pre-tested semi-structured questionnaire. Results: The mean age of the participants was 42.24 (±13.72) years. Among the auto-rickshaw drivers, 82% perceived stress, 64% had hearing difficulty, and 74% complained of lack of sleep following exposure to a high level of noise. However, the perceptions were comparable among the comparison group and the differences were not statistically significant. The mean average peak level of noise exposure among drivers and their comparison group was 91.64 (±7.37) dB and 91.98 (± 8.06) dB, respectively, but were not different statistically. Around 52.94% of the service-sector respondents and 48% of the drivers were exposed to the lower cumulative noise levels. Those having a higher level of cumulative noise exposure, had a higher odds of feeling irritated (Odds ratio [OR]: 2.182, 95% confidence interval [CI]: 0.845–5.636), feeling stressed (OR: 5.805, 95% CI: 1.552–21.708), having palpitation (OR: 3.694, 95% CI: 1.264–10.793), and lack of sleep (OR: 3.020, 95% CI: 1.006–9.066). Conclusion: Stress and lack of sleep were the most important perceived effects of noise exposure. The exposures to the higher cumulative noise level in specified groups were more important in relation to quantifying perceived symptoms than the average peak noise level.

“…These classifications of noise are emitted in the mines at varying frequencies and intensities (Basner et al, 2014). Excessive occupational noise levels and exposure to such noise have been documented to cause occupational noise-induced hearing loss (ONIHL), tinnitus, disturbance in speech communication and increased risks of accidents (Lie et al, 2016;Lopes, Otowiz, Lopes, Lauris, & Santos, 2012).…”

Results: Some of the case studies used have cited a reduction in the noise intensity emitted by machinery from a range of 93 dBA -104 dBA to a range of 90 dBA -94 dBA, demonstrating quite a significant reduction in the noise emission of the equipment. This article further provides recommendations on how South African mines could contextualise these methods. Conclusion:One of the key recommendations is encouraging the South African mining industry towards the documenting and publishing of those engineering noise control methodologies that have proven to be effective for shared best practice. A need was identified for extensive research to be conducted and documented evidence to be made available to assist the South African mining industry with locating and assessing current engineering controls available in South Africa. Machines and processes that require noise control should be identified and, lastly, the current barriers to the use of engineering noise control methodologies should be identified, with the main goals of finding ways to overcome the noise challenges in the mines.

“…O ruído no trafego é um dos principais causadores de poluição sonora. Estudos têm sido descritos com o propósito de verificar o comprometimento da saúde em motoristas mediante exposição ao ruído, visto que a atuação dessa classe de trabalhadores é de tamanha responsabilidade, os quais são responsáveis pelo cuidado e segurança de seus veículos, cargas valiosas e muitas vezes tóxicas, além do cuidado com a sua própria saúde, sendo desafiados a cada dia em suas jornadas de trabalho 3 .…”

RESUMOO estudo objetivou analisar os achados audiológicos em motoristas de caminhão, bem como analisar os sintomas auditivos e extra-auditivos presentes nesta população. A amostra foi composta por nove motoristas de caminhão do sexo masculino. A coleta dos dados deu-se pela entrevista fonoaudiológica e avaliação audiológica básica. Os resultados revelaram que a presença de zumbido, a dificuldade para entender a conversação e o incômodo a sons intensos foram os sintomas auditivos mais relatados. Já os extra-auditivos, o nervosismo foi o mais relatado. Quanto aos achados audiológicos, 88,88% apresentaram média tritonal dentro dos padrões da normalidade. Entretanto, observou-se queda do limiar auditivo nas frequências de 3000, 4000 e 6000 Hz, sugerindo perda auditiva por exposição a ruído. Mediante aos achados, acredita-se ser necessário desenvolver ações de prevenção, visando melhores condições de trabalho nesta classe de trabalhadores. Palavras-chave: audição, perda auditiva, motoristas.
