Principle of Operation
Image: Visual representation of sound amplification and noise reduction.
These electronic ear defenders utilize internal circuitry to amplify low-level sounds, such as speech or environmental noises, allowing you to maintain awareness of your surroundings. Simultaneously, they feature a Noise Reduction Rating (NRR) of 24dB and actively suppress harmful impulse noises above 82dB, protecting your hearing from sudden loud sounds like gunfire. The stereo sound design aids in quickly identifying the direction of sounds.
