What is the risk of noise exposure and how can it be mitigated?

• A. No Health Effects from Noise
• B. Noise Only Affects Mood
• C. Prolonged Exposure Can Cause Hearing Loss; Mitigate with Hearing Protection and Engineering Controls
• D. Noise Cannot Be Controlled

Answer: (C)

Noise exposure can damage hearing when you’re around loud sounds for extended periods. The risk grows with higher sound levels and longer exposure, and even sounds you don’t find disruptive at first can gradually harm the inner ear’s delicate structures, leading to permanent hearing loss and often tinnitus. To reduce this risk, use a combination of controls: engineering controls to remove or lessen noise at the source or along its path (like enclosing noisy equipment, adding mufflers, or dampening vibrations); administrative controls to limit how long people are exposed to loud environments (rotating workers, scheduling noisy tasks to minimize time in noise); and personal protective equipment such as properly fitted earplugs or earmuffs as a last line of defense when exposure can’t be reduced enough. It’s important to recognize that noise can have health effects beyond mood, and it can be controlled with the right mix of strategies.
