Protective Hearing is provided by which combination?

• A. Earplugs and Air Defenders
• B. Hearing Aids
• C. Noise-Canceling Headphones
• D. Safety Glasses

Answer: (A)

Hearing protection is strongest when sound is blocked from reaching the ears, and using two protective devices together increases that blocking effect. Wearing earplugs to seal the ear canal and earmuffs (often called ear defenders) over the ears adds their attenuation values, giving a higher total reduction than using either alone. This double protection is essential in very loud environments. Hearing aids are designed to improve hearing, not protect it, so they don’t reduce exposure to loud noise. Noise-canceling headphones can lower some ambient sound but are not rated for industrial noise levels and may not provide the level of protection needed. Safety glasses protect the eyes, not the ears.
