The Bose combat vehicle crewman headset provides superior communication performance. Also, it provides hearing protection for crew members in tracked armored vehicles. This Army CVC headset is a second generation active noise reduction communication solution. US Army tests indicate a speech intelligibility score of 89%, as well as greater hearing protection (compared with the conventional DH-132 helmet, when used with a modern ICS like the VIC-3). Safe exposure time for crew members operating in high-noise environments is increased by a factor of 10.
