"Triport® Tactical Headset
Military studies show that reducing noise improves mission effectiveness. As maneuvers involving light/wheeled armored vehicles increase in number, the ability to communicate intelligibly within them becomes more and more important.
Building on more than ten years’ experience in providing CVC headsets for tank and tracked vehicle applications, Bose introduces the TriPort® tactical headset. Designed specifically for use in wheeled armored vehicles such as the M-1114 “up armored” HMMWV “Humvee” and Stryker, this active noise reduction headset offers the following features and benefits:
Features and benefits
Full-spectrum noise reduction
Proprietary technologies allow a narrow profile earcup with full-spectrum noise reduction. The technology in Acoustic Noise Cancelling® headsets reduces environmental and mechanical ambient noise significantly, increasing safe exposure time more than tenfold over that provided by passive headsets.
Comfortable fit
Narrow-profile earcups allow a comfortable fit with many infantry helmets. In addition, the TriPort® tactical headset is up to 33% lighter than conventional noise reducing tactical headsets. The proprietary, ergonomic design of the earcushions and the internal earcup volume ensure good fit over a wide range of head and ear sizes.
Talk-through capability
This user-selectable, binaural feature permits monitoring of the ambient sound environment. Crewmen can disconnect from the vehicle intercom system and communicate with other crewmen standing nearby or listen for threats—without removing their helmets. Internal circuitry prevents transmission of extremely loud noises, protecting the user.
Compatibility with NBC protective equipment
The TriPort® tactical headset may be operated with NBC (Nuclear-Biological-Chemical) protective masks, allowing the user to realize the benefits of clearer audio and noise reduction even in NBC environments.
Flexible boom microphone
The flexible boom allows easy, precise adjustment and may be mounted on the left or right earcup, depending on user preference. The modular design of the cable / boom microphone assembly facilitates field replacement and adaptation to different intercommunications systems.
