Is it true that Noise Induced Hearing Loss (NIHL) results from prolonged exposure?

Noise Induced Hearing Loss (NIHL) is indeed a result of prolonged exposure to high levels of noise. This type of hearing loss occurs when the delicate hair cells in the inner ear are damaged due to consistent exposure to loud sounds over time. Unlike temporary threshold shifts in hearing, which might occur after short bursts of loud noise, NIHL develops gradually and can lead to permanent hearing impairment. The longer and more frequently a person is exposed to high decibel levels—especially in occupational settings such as construction sites, factories, or even at concerts—the greater the risk of sustaining permanent hearing loss. Understanding the duration and intensity of noise exposure is crucial for implementing proper hearing conservation practices.
