Hearing conservation programs aim to prevent initial occupational hearing loss; preserve and protect remaining hearing; and equip workers with the knowledge and hearing protection devices necessary to safeguard themselves. Employers must measure noise levels; provide free annual hearing exams, hearing protection, and training; and evaluate the adequacy of the protectors being used (U.S. DOL, OSHA, n.d.-f). A hearing conservation program requires five components: (1) sound exposure monitoring, (2) noise controls, (3) education and motivation, (4) hearing protection, and (5) audiometric monitoring. Sound exposure monitoring must be conducted during a typical work situation and include all continuous, intermittent, and impulsive noise within an 80 dB to 130 dB range (U.S. DOL, OSHA, 2002).

HL may also result from controllable factors such as prolonged exposure to excessive noise. Excessive noise is not an absolute value but is defined by national or State workplace health and safety legislation, both in Australia and other developed countries. In all states in Australia, excessive noise is defined as an average noise level of more than 85 decibels (dBA), for a typical 8-h workday for five (5) days a week. When noise exposure exceeds this level for a prolonged period of time, it may cause what is known as noise-induced hearing loss (NIHL) (Safe Work Australia, 2004). Excessive noise levels are common in a range of industries including coal mining (Roberts et al., 2017; Kurmis and Apps, 2007), where machinery and technologies typically produce noise levels in excess of 85dBA. If young people with early onset hearing loss from social noise are subsequently employed in industries renowned for excessive noise exposure, their vulnerability to and risk of occupational hearing loss will be increased, underlining the importance of identifying and targeting them for hearing conservation programs.

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).
The α9α10 nicotinic acetylcholine receptor: a compelling drug target for hearing loss?

Prevention remains the best option for limiting the effects of acoustic trauma produced by exposure to loud sounds. This requires education, regulations, legislation, and workplace noise policy enforcement. A prospective, randomized controlled assessment of the short- and long-term efficacy of a hearing conservation education program in Canadian elementary school children has shown that a community-based health promotion project around hearing loss aids students to develop their knowledge and skills in health advocacy, highlighting the importance of hearing protection education [37]. Moreover, a Cochrane systematic review has shown that enforcement of legislation and better implementation of occupational hearing loss prevention programs can reduce noise levels in workplaces [38]. However, not all countries have and/or enforce hearing protection regulation programs [39].
