PICVC - ANR HELMET




ACTIVE NOISE REDUCTION (ANR) PICVC HEADSET

Traditional helmets rely on passive attenuation, creating a physical barrier around the ear in an attempt to seal out noise.  This works well for high frequency sounds.  However, it fails to block the low frequencies of engine noise and other background rumble.

BOSE® electronic Acoustic Noise Cancelling® headset technology actively counters this low frequency noise by generating out-of-phase "anti-noise" in the low frequency range.

Speech signals are not affected – but since background noise is abated, speech intelligibility greatly improves.

Measured by the objective method described in MIL-STD-912, BOSE Acoustic Noise Cancelling technology provides more than 10 decibels better protection than conventional passive hearing protectors.  The result is clearer communications, less fatigue and - ultimately - a more effective military operation.
