Name two preventive measures to protect against noise-induced hearing loss.

• A. Use hearing protection only
• B. Use hearing protection and limit exposure to loud noises; keep exposure under ~85 dB for extended periods
• C. Increase exposure to loud noises
• D. Ignore exposure and rely on earplugs

Answer: (B)

Protecting against noise-induced hearing loss hinges on two practical steps: lower the sound energy reaching the inner ear and limit how long you are exposed to loud noises. Wearing hearing protection, such as earplugs or earmuffs, reduces the level of sound reaching the cochlea, while shortening exposure time minimizes cumulative damage from repeated noise. The most effective approach combines both strategies: use protection and actively limit exposure, aiming to stay at or below about 85 dB for extended periods. In general, once the level rises above 85 dB, safe exposure time drops quickly (roughly halving for each additional 3 dB). Together, these measures substantially lower the risk of hair-cell damage and subsequent hearing loss.
