About ANR

In the simplest terms, Direct Noise Cancelling (DNC) or Active Noise Reduction (ANR), is the technique of cancelling noise disturbances by a system, which drives a speaker to generate mirror images of the sound frequencies of the outside noise. Additionally, the PILOT DNC system directs its noise cancelling at low frequency noise while using its Enhanced Voice Intelligibility (EVI) circuitry to enhance the speech frequencies (500–1000 Hz) by 2–4 dB on all audio input. This unique combination of noise cancelling and speech enhancement makes for significantly increased intelligibility. All PILOT active headsets contain these features.

It should be noted that ANR systems are most effective at targeting the low frequencies. Mid-range and high frequencies are attenuated passively by the ear cup design and its characteristics. The actual mass of the ear cup and the volume inside the ear cup all help to improve passive noise attenuation. For the best hearing conservation and preservation of one’s hearing, the prospective user should choose a headset which combines the best passive and active technologies to cover the wide range of frequencies one might encounter. A full brochure is available upon request for each DNC headset.
