Hearing loss affects approximately 360 million people worldwide. It can be caused by a variety of factors, ranging from a perforated eardrum or a malformation in the ear to allergies or an ear infection

Mark Cullen from Stanford University advocates for increased education and awareness for employers. Many employers simply provide hearing protection gear, which is often taken off by employees when they are unsupervised. Cullen also cites solutions such as building noise barriers. While some companies may consider training or barrier construction to be costly, approximately $242 million is spent annually on worker’s compensation claims related to hearing loss. Just as with other safety equipment, employer support for hearing health devices should cost much less than a occupation injury.

One of the most common causes of hearing loss is exposure to loud noise, also known as noise-induced hearing loss (NIHL). This kind of hearing loss can be caused by either one loud, intense burst of noise or frequent exposure to loud sound over a long period of time. People of all ages are affected with NIHL, particularly now with a combination of continuous earbud use and loud music.

A recent article published by USA Today used statistics from the Center for Disease Control and Prevention to conclude that hearing loss is actually the most common injury that occurs in the workplace. 22 million Americans a year are exposed to hazardous levels of occupational noise. The industries most negatively affected in this regard are mining, construction and manufacturing.

Earlier this summer, the Department of Labor launched a campaign called “Hear and Now”, which challenges the public to submit innovative technology and ideas to target workers and alert them to hazardous workplace noise levels. But some critics question whether current regulations are sufficient. Due to these concerns, the Occupational Safety and Health Administration (OSHA) is planning to issue a request for information later this year, which will focus on construction sites. This request is aimed at working out whether higher standards are required and whether companies are adequately complying with the current requirements.

A study conducted by Mark Cullen of Stanford University, cited in the USA Today, found that people who most often suffer from workplace noise-induced hearing loss are actually those working in moderately noisy jobs as compared with jobs in high-noise environments.

In high-noise environments, people are aware of the risks to their hearing, so they usually wear hearing protection gear. In positions that involve moderate-noise, people are less likely to be aware of the risks posed by continuous exposure to noise and so do not take similar precautions. Another Cullen study showed that if workers are made aware of the risks, they can be relied upon to voluntarily monitor their noise exposures on a daily basis.
