Hearing loss can be prevented by wearing what?

• A. Ear plugs
• B. Safety glasses
• C. Dust mask
• D. Hard hat

Answer: (A)

Preventing hearing loss comes from reducing how much sound reaches the ears. Ear plugs do this directly by fitting into the ear canal and dampening the vibrations of sound, so the inner ear is exposed to much less noise. When they’re inserted correctly, they’re an effective, targeted way to protect hearing in loud environments. Other gear like safety glasses, a dust mask, or a hard hat protects other areas (eyes, lungs, head) but doesn’t directly prevent hearing loss. In very noisy settings, you might use ear plugs with additional protection, but the key to preventing hearing loss is lowering the sound reaching the ears.
