Abstract

Background: Occupational noise-induced hearing loss (NIHL) represents a substantial global public health concern. Regulatory agencies such as the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupation Safety and Health (NIOSH) aim to establish noise exposure limits in occupational settings, yet certain professions, such as firefighting, remain at a heightened risk. Although research has been conducted on noise exposure and hearing protection in career firefighters, a lack of research exists on volunteer firefighters. The purpose of this study was to 1) establish the extent that volunteer firefighters are currently educated on hearing conservation and hearing protection 2) define how often volunteer firefighters wear hearing protection while firefighting and 3) determine the attitudes and perceptions towards wearing hearing protection in various scenarios.

Methods: A survey was designed and distributed to volunteer firefighters in Nassau County, New York. The study was proposed to provide valuable insights that can inform and enhance hearing safety measures of individuals by increasing awareness and advocacy for hearing conservation in volunteer firefighters.

Results: Despite 80% of participants expressing being exposed to loud noise while firefighting, one respondent indicated they wear hearing protection while firefighting. Individuals with more than 15 years of experience in the fire department exhibit a higher proportion of participants who perceive themselves to have a hearing loss.

Discussion: A significant number of participants noted a personal decline in their hearing since volunteering as firefighters, with a considerable portion failing to seek professional hearing healthcare despite the self-perceived loss. These findings highlight the critical need for hearing conservation programs designed to educate firefighters about workplace-related noise exposure and the strategies available to mitigate its impact on hearing.

Conclusion: Overall, greater efforts are needed to raise awareness about NIHL among volunteer firefighters, aiming to educate both them and the broader community about the importance of hearing health.
