About RA195 iCombat
RA195 iCombat headset is compatible with many close-fitting ballistic helmets for use in high noise environments. The headset attenuates higher-frequency ambient noise through Passive Noise Reduction (PNR), using the mass and volume of the headset. For lower frequencies it relies on supplementary attenuation from low-profile Active Noise Reduction (ANR) modules in each earcup.
RA195 Headset Technology
The RA195 headset design provides good Passive Noise Reduction (PNR), effective at higher frequencies, while dedicated independent low-profile Active Noise Reduction (ANR) modules in each earshell deliver improved noise reduction at lower frequencies. ANR cancels unwanted signals by superimposing an identical signal in antiphase. Low-frequency noise within the earshell is detected, phase inverted and driven back via the earphone for effective cancellation.
RA195 Product Details
Designed for comfort and compatibility, RA195 features contoured earshells that fit most infantry helmets, a fully adjustable neckband that accommodates 5th-95th percentile head size with optimal force to maintain an effective acoustic seal in vehicles subject to shock and high vibration, without degradation of acoustic performance, to provide effective noise reduction and reduce mission fatigue.
High noise attenuation
Passive and Active Noise Reduction (ANR) features protect the hearing of users exposed to high levels of continuous noise; the headset achieves high levels of noise attenuation.
Local sound awareness and talk-through
The user can enable talk-through to hear local environment sounds at safe levels (<85dBA), to maintain situational awareness of hazards or permit face-to-face conversations without defeating the hearing protection.
Boom-mounted, noise-cancelling microphone for discrimination between close speech and high levels of ambient noise, with plastic-foam cover for wind-noise protection.
The adjustable headstrap locates the earshells correctly over the ears. It can be fitted over or under the helmet and incorporates Velcro strips for simple adjustment and rapid attachment and removal.
The headset downlead is factory configured and terminated into the required connector with pinout and audio levels to match the attached equipment, enabling the headset to support mono or stereo communications. The built-in Voice Operated Switch (VOS) automatically opens communications channels without needing a press-to-talk (PTT) switch. Optional electronic talk-through features an on/off control switch mounted on the earcup. The headset Active Noise Reduction (ANR) and optional talk-through is powered from the attached equipment (18V to 28V DC supply required).
