Which term describes hearing protection used to reduce exposure to loud sounds?

• A. Passive Hearing Protection
• B. Noise
• C. Conductive Wrist Strap
• D. ESD

Answer: (A)

Hearing protection that reduces exposure to loud sounds works by blocking or attenuating sound energy before it reaches the ears. This is called passive hearing protection. It relies on a physical barrier, like foam earplugs or earmuffs, and doesn’t require power or electronics. That makes it the right term for devices that simply lower noise exposure. The other terms aren’t about protecting hearing: noise is the sound itself, not the protection. A conductive wrist strap and ESD relate to electrical discharge control in electronics work, not hearing protection.
