WHY DO YOU NEED GOOD PASSIVE HEADSET DESIGN COMBINED WITH ACTIVE NOISE CANCELING (ANC) TO ACHIEVE OPTIMAL NOISE CANCELING PERFORMANCE?

Passive Noise Reduction
Any stereo headset or headphone will provide some level of passive noise reduction. In fact, any device that provides a physical barrier to your ear canal will limit your exposure to noise. Industrial noise canceling headphones fit over the ear and are specially constructed to maximize noise filtering. They are packed with layers of high-density foam or other sound-absorbing material, which makes them heavier than other headphones but reduces the background noise by about 15 to 20 dB. This level of noise reduction is essential in workplaces with extreme noise levels, such as airport ground crew areas or factories. Not every work environment requires that level of noise canceling, however. For office workers, a more lightweight, over-the-ear or in-the-ear headset typically provides the required passive noise reduction more comfortably.

Active Noise Canceling (ANC)
Beyond passive noise canceling, which involves physically blocking sound, ANC is a technology built into many of our products that further enhances the user experience. This technology uses additional microphones on the back of each speaker that respond well to low-frequency (80 to 700 Hz) background noise.
These microphones pick up the background noise, feed it into the ANC circuitry, invert it, then direct it into the same audio path. This happens very quickly, <500 milliseconds, which is not perceptible to the user.
The result? The original background noise and the inverted noise cancel each other, leaving just the audio the user wants to hear.

WHY ARE THERE TWO LEVELS OF ANC ON VOYAGER 8200 UC (MID AND HIGH)?
The Voyager 8200 UC features two levels of ANC. The first one, “mid,” is set at a similar level to the Voyager Focus UC, optimized for typical office noise. The second level “high,” is about double the intensity of the mid level. The high-level ANC is very useful for noisier environments, such as airports or coffee shops, but may be fatiguing for long periods of use in an office environment depending on how sensitive the user is to the effects of ANC. The option to adjust ANC intensity settings allows users to choose their own individual comfort level.

Wherever you work, noise can be distracting. So whether you’re in an open office or on a crowded flight, taking calls or listening to music, the boomless Voyager 8200 UC Bluetooth® headset with active noise canceling lets you focus on what’s important, in comfort and style. Hear music and conversations with complete clarity. All tones, from high to low and everything in between, sound full and natural. Need to tune out distractions? The hi-fi stereo sound and dual-mode active noise canceling cut background noise while the dual-paired microphones keep the focus on your voice.
