Active hearing protection uses electronic circuitry—such as microphones, a processor, and actuators—to detect noise and actively reduce it in real time. This is different from passive protection, which blocks sound purely through physical barriers like foam or padding and doesn’t involve any electronics. The term specifically describes devices that actively dampen noise, not just block it or label the device in general terms. That’s why this option is the best fit.
