Where is the highest percentage of workers exposed to noise-induced hearing loss (NIHL) found?

The highest percentage of workers exposed to noise-induced hearing loss (NIHL) is found in the manufacturing sector. This is primarily due to the nature of the work environments in manufacturing, which often involve heavy machinery, power tools, and equipment that generate high levels of noise. Exposure to these loud sounds can be continuous and at high decibels, significantly increasing the risk of hearing damage over time.

Manufacturing facilities are typically equipped with various machines that operate at decibel levels above those considered safe for prolonged exposure. Workers in these environments may not only be exposed to loud noise on a daily basis, but they also may have limited opportunities to use personal protective equipment, such as hearing protection, effectively. Furthermore, the culture in some manufacturing settings may not prioritize hearing conservation as strongly, leading to higher rates of NIHL as workers might not be adequately informed about the risks or provided with necessary preventative measures.

In contrast, while other fields such as construction and healthcare can also pose risks for hearing loss, the manufacturing industry consistently reports higher incidences of NIHL due to the scale and intensity of noise exposure inherent in the work performed.
