What term describes earplugs and earmuffs with low-level protection?

• A. Passive Hearing Protection
• B. Noise
• C. Electrical Protective Devices
• D. ESD Control Program

Answer: (A)

Hearing protection devices come in two broad kinds: passive and active. Earplugs and earmuffs described as providing low-level protection are examples of passive hearing protection. They achieve attenuation purely through physical means—seal, damping, and material properties—without any powered electronics. Because the term “low-level” suggests modest attenuation, the non-powered, passive category is the best fit. The other options don’t describe a type of hearing protection: “Noise” is the hazard, not a device; “Electrical Protective Devices” relate to electrical safety gear; and “ESD Control Program” is about preventing electrostatic discharge, not hearing protection.
