Hearing damage at what noise frequency is viewed as typical of industrial exposures?

• A. 250 hertz
• B. 1000 hertz
• C. 2000 hertz
• D. 4000 hertz

Answer: (D)

Hearing damage related to industrial exposure is most commonly associated with higher frequencies, particularly around 4000 hertz. This frequency range is significant because many industrial environments, such as manufacturing or construction sites, produce sounds that are particularly damaging to hearing at this level. Long-term exposure to sounds at or above 85 decibels can lead to noise-induced hearing loss, and the higher frequencies, notably around 4000 hertz, are typically the first to be affected. This phenomenon occurs because the hair cells in the cochlea responsible for detecting high-frequency sounds are more vulnerable to damage from loud noises. In comparison, while lower frequencies like 250, 1000, and 2000 hertz are important in the broader spectrum of hearing, they do not exhibit the same level of vulnerability in industrial settings. Therefore, understanding that 4000 hertz is the frequency typically viewed as characteristic of industrial hearing damage helps in identifying at-risk populations and implementing proper hearing conservation strategies in workplaces.
