From the Guidelines
Industries most associated with hearing loss include the mining and wood products industry, building and real estate construction, and the agriculture, forestry, fishing and hunting sectors, with approximately 27%, 23.5%, and 15% risk of hearing damage due to noise exposure, respectively. These sectors expose workers to high levels of noise from machinery, equipment, and vehicles that can cause noise-induced hearing loss (NIHL) when sound levels exceed 85 decibels over prolonged periods, as reported in a study published in the International Journal of Occupational and Environmental Medicine 1.
Key Industries at Risk
- Mining and wood products industry: 27% risk of hearing damage due to noise exposure
- Building and real estate construction: 23.5% risk of hearing damage due to noise exposure
- Agriculture, forestry, fishing and hunting sectors: 15% risk of hearing damage due to noise exposure
Prevention and Early Detection
Prevention requires comprehensive hearing conservation programs including engineering controls to reduce noise at the source, administrative controls to limit exposure time, and personal protective equipment such as earplugs or earmuffs, as suggested by the study 1. Regular audiometric testing is essential for early detection of hearing changes in workers in these high-risk industries.
Additional High-Risk Groups
Other groups at risk of hearing loss include military personnel, who experience significant noise exposure from weapons, aircraft, and vehicles, as well as entertainment and music industry employees, who are exposed to loud music and other sounds, as mentioned in the study 1.
From the Research
Industries Associated with Hearing Loss
The industries most associated with hearing loss are:
- Mining: The mining sector had the highest prevalence of workers with any hearing impairment, and with moderate or worse impairment 2
- Construction: The construction sector had a high prevalence of hearing loss, with several sub-sectors exceeding the overall prevalence 3
- Manufacturing: Workers in the manufacturing sector, particularly in Wood Product Manufacturing, had higher risks for hearing loss 4
- Oil and Gas Extraction: The Oil and Gas Extraction sector had a prevalence of hearing loss of 14%, with some sub-sectors having higher prevalences 5
Prevalence of Hearing Loss by Industry
The prevalence of hearing loss varies by industry, with:
- Mining: 24% 5
- Construction: 23% 3
- Manufacturing: 18% of workers had hearing loss, with higher risks in certain sub-sectors 4
- Oil and Gas Extraction: 14% 5
- Healthcare and Social Assistance: consistently high prevalence of hearing loss 6
Sub-Sectors with High Prevalences of Hearing Loss
Several sub-sectors have high prevalences of hearing loss, including:
