A NoiseBuster ANR Earmuff uses a microphone inside the ear cup (1) to listen to noise coming into the ear (2). Using electronics (3), the system takes that information and uses it to create a noise wave that is identical to, but directly opposite of, the one coming into the ear. The "anti-noise" wave is output through a speaker (4), also located in the ear cup. When the two waves (the noise wave and the anti-noise wave) meet, the noise is significantly reduced (5). ANR Protection ANR is the most effective defense against low frequency noise. Low frequency noise consists of powerful sound waves that can travel great distances and cannot be absorbed by conventional passive materials.  Noises generated by engines, fans, motors and other similar devices are typically dominated by low frequencies--frequencies that cannot be stopped by passive earmuffs. In addition to the detrimental effect it has on hearing, low-frequency noise creates another, perhaps even more serious effect. Because low-frequency noise masks speech, it is difficult for a person to hear and comprehend speech and warning signals when exposed to such noise. Passive Protection The passive component of the NoiseBuster ANR Earmuff delivers an ANSI-certified 26 NRR (Noise Reduction Rating), providing superior attenuation of mid- and high-frequency noise.
