The purpose of the Occupational Noise Exposure Standard (29 CFR 1910.95; see Appendix A) is “to protect workers with significant occupational noise exposures from hearing impairment even if they are subject to such noise exposures over their entire working lifetimes” (U.S. DOL, OSHA, 2002, p. 1). The standard requires employees exposed to noise at or above 85 decibels (dB) averaged over eight working hours, or an eight-hour time-weighted average (TWA) are included in the company hearing conservation program.

Continuous/steady-state noise: Nations have various standards for occupational noise exposure.Action level (exposure level at which hearing testing, health education training and availability of hearing protection are required) typically 85 dB over an 8-hour time period.Maximum exposure level above which employees cannot be exposed is 115 dB(A) in the United States, Exposure Limit Value is 87 dB(A) in Europe.

However, worldwide, occupational noise exposure represents one of the most prevalent, potentially preventable, sources of health impairment. Recent reports suggest that, outside Europe and North America, up to 25% of adult males of working age have evidence of occupational NIHL. This seems to be a particular problem in those countries moving from agriculture to a stronger manufacturing base for their developing economies.4

Occupational noise refers to undesired sound present in the workplace [1], and such exposure can result in auditory and non-auditory health effects, where examples of auditory health effects are tinnitus and occupational hearing loss, while examples of non-auditory health effects include annoyance, sleep disturbance, impaired attention, communication impairment and cardiovascular disease. Undesired noise, especially one-time exposure to impulse noise, such as from gunshots, can lead to hearing loss [2]. Noise-induced auditory symptoms (NIASs) refer to the symptoms that develop after exposure to loud noise in excess of 85 dB, typically at the temporary-threshold shift (TTS) stage when the condition of the ears’ sensory cells in the cochlea becomes fatigued [3]. If not prevented, this can further develop into a permanent and irreversible condition, noise-induced hearing loss (NIHL).

Higher prevalence of hearing loss is often found in males (Hietanen et al., 2005; Stevens et al., 2011; Uchida, Nakashima, Ando, Niino, & Shimokata, 2003). However, there was no statistically significant association between hearing loss and sex in the present study. Educational level has also been associated with the prevalence of hearing loss, where lower educational level increased the likelihood of hearing loss (Hietanen et al., 2005). However, there was no significant association noted in the present study. Occupational noise exposure leads to increased risk of noise induced hearing loss (Ward, Royster, & Royster, 2000). However, occupational noise exposure was not significantly associated with hearing loss in this study. However, age may have masked occupational noise exposure effects. The more major limitations of this study should also be acknowledged. The study sample size was relatively small and the exploration of ‘feasibility’ was limited to prevalence aspects and to gauging willingness of elderly patients to participate in audiometric assessment and intervention. Further research that looks at prevalence in large outpatient clinic groups and explores other aspects of feasibility – such as availability of required health care resources such as audiology services – is warranted.

The cumulative noise exposures, LAeq8h for sleep and LAeq16h for work time, were calculated for each crewmember, as well as the number of impulses, LZpeak, that exceeded 115 dB peak. For comparison with the well-known NIOSH recommended exposure limit for occupational noise (National Institute for Occupational Safety and Health 1998), the 8 h time-weighted average (TWA) of 85 dBA, the LAeq16h were also converted to TWA-equivalent values. The conversion was calculated using D is the daily dose, or percentage of time the noise exposure was at a hazardous level (National Institute for Occupational Safety and Health 1998). The duration in minutes T, at which a given level L, becomes hazardous is L = LAeq16h and C = 16 h or 960 min.
