“…The noise levels reported in this study [70 -96 Leq dB(A)] are consistent with levels that documented in the literature for steel industries [3,6,12,13]. In the current study about 40 % of hearing protection device non-users exposed to a daily noise level liable to cause noise induced hearing loss [a daily Leq above 85 dB (A)].…”

“…The finding of this study that the majority of the workers had formal education and low duration of service, but few of them were aware about the health effects of noise and the safety measures, supports the conclusion of the previous researchers that awareness appears to be derived from the personal experience of working in a noisy environment for many years, rather than from educational input [12,17].…”

“…In addition, one study in Malaysia found that 36 % of the noise exposed workers knew that exposure to excessive noise results in hearing loss [16]. Regarding the safety measures that should be taken to protect workers from noise, almost 2% of the workers were aware about them in this study, compared with 92% reported by Ologe et al [12].…”

“…In this investigation, few workers (4.1%) claimed awareness about the health effects of noise. In other studies 29-93% of workers were aware about the health effects of noise [4,[12][13][14]. Svensson et al stated that 95% of the Swedish workers were aware that loud noise could damage their hearing [15].…”

Abstract:This cross-sectional study investigated noise annoyance, awareness and practice among the workers in two steel factories in UAE. The study involving 468 steel workers randomly selected. Noise exposure was estimated using the integrated sound level meter. A structured interview questionnaire was used to assess the noise annoyance, awareness and practice of workers towards the noise. The results showed that about 89 % of the workers exposed to a daily Leq above the permissible level which is 85 dB (A) and 45 % of them had never used any hearing protection devices. About 58% of the workers experienced a moderate or high degree of noise annoyance. Only 4.1% and 1.9 % of the workers aware about the health effects of noise and the methods of prevention respectively and awareness was positively associated with noise exposure. Few workers (13.2%) used the hearing protection devices during the working time. Thus workers within both factories are at high risk of developing noise annoyance, and other related ailments due to excessive occupational exposure to noise, and non-use of hearing protection devices. There was an association between noise annoyance and noise level and any one of them could influence the workers to use the hearing protection devices. There is a need to have a hearing conservation program in both factories one of its main components is education to raise the awareness of workers about noise hazards and methods of prevention. Finally, the factor noise annoyance should be incorporated into all future studies on the use of hearing protection devices.

Aim The study sought to measure the noise levels in an urban community and assess the hearing levels of persons working within the community. Subjects and methods Noise levels were measured in selected locations in Ibadan, southwest Nigeria, using a sound level meter CEL 269 (CEL Instruments UK Ltd.). Measurements were done between the hours of 08:00 and 15:00. Audiometric screening was done on 51 persons working within the community to determine the occurrence of hearing impairment. Results The noisiest locations were workshops using machines such as saw mills, 95-102 dBA; carpentry tools, 87-101 dBA; printing presses, 85-88 dBA; and grain mills, 88-105 dBA. Music shops also constituted a nuisance with noise levels of 89-99 dBA. Roadside noise levels on major road junctions were 86-90 dBA and 61-65 dBA on side streets. Noise levels in designated markets ranged from 65-69 dBA and 61-81 dBA in street markets. Within residential areas, noise levels ranged from 39-41 dBA in low-density areas to 55-59 dBA in high-density areas. Audiometric screening showed that 28 participants (55%) had normal hearing. Mild and moderate hearing impairment was recorded among 17(33%) and 6 (11.7%) participants, respectively. Of the 23 who were hearing impaired, 10 had bilateral impairment. The prevalence of hearing impairment increased with age from 14% in the 2nd decade to 75% in the 5th decade. Conclusion Noise levels in several areas of the city exceed WHO guideline values and constitute a public health hazard to residents and street workers. There is a need for regulation and control of the social and economic activities that generate noise. This may reduce the occurrence of hearing impairment and other adverse health outcomes in the general population.
