Hearing loss is typically a gradual process, and by the time its effects are noticeable, it is often too late to do anything about it. Hearing loss is more common than most people realize, according to the CDC, an average of 22 million U.S. workers are exposed to dangerous levels of noise in the workplace annually. Hearing loss can be caused by several different factors (age, illness, etc.), however, the most common of these is noise-induced hearing loss, especially among older adults.

According to the National Institute on Deafness and Other Communication Disorders (NIDCD), long or repeated exposure to sounds at or above 85 dB(A) can cause hearing loss. The louder the sound, the shorter the amount of time it takes for noise-induced hearing loss (NIHL) to occur. Based on the study Hearing Loss Among Construction Workers: Updated Analyses, 58% of older construction workers now suffer from significant hearing loss, which was often a result of not taking the appropriate precautions while working in high-noise worksites. A study by Work Care found that employers pay $242 million a year in worker compensation for hearing loss, and these costs were higher in construction than in any other industry.
