Overview

The RA108 was designed to meet the communication and hearing protection needs of U.S. mechanised infantry in tracked vehicles. Close fitting PASGT-style ballistic helmets still continue to pose a 'noise reduction' challenge in these high noise vehicles.

Key Features

• Passive and ANR versions
• Talk-Through
• Compatible with close fitting ballistic helmets
• Removable microphone boom arm
• New, comfort improved earcushions
• Versions for most popular intercom systems

Benefits

ANR in combination with the passive noise attenuation afforded by the RA108's earshell mean excellent speech intelligibility and hearing protection, the latter, despite its slimline nature. The ability to wear the headset with even the most close fitting ballistic helmet is a direct consequence of that slimline form.

A neckband connecting the earcups allows the headset to be donned & doffed without removing the ballistic helmet; vital when exiting a vehicle under fire.

The Talk-Through facility means that normal face-to-face conversation can be had without having to remove the headset.

Applications

Since it was originally fielded in the U.S., the RA108 is being used elsewhere including Canada, Australia, Austria and Spain for infantry commander and passenger applications, in both tracked and wheeled APCs.

Overview

The RA180 was originally designed for the British Army's Challenger II and continues to offer class leading attenuation through a combination of Passive and Active Noise Reduction (ANR)

Key Features

• High noise attenuation, circa 35 dB with ANR
• Talk-Through
• Choice of electret or dynamic noise cancelling micophones
• Immunity from radiated EMC fields up to 50V/m
• New, improved comfort earcushions

Benefits

Excellent speech intelligibility and hearing protection are assured through the combination of passive and active noise reduction, while new earcushion materials mean that they are less prone to 'work hardening' and hence remain comfortable when worn for long periods of time.

Applications

Crewgard's excellent noise attention is suitable for tracked Combat Vehicle Crew or fast-jet Ground Crew or indeed any high-noise application where a close fitting ballistic helmet is not required.

Overview

Originally designed for the British Army Mk VI combat helmet, the RA195 has been field proven through several conflicts and has received a number of product improvements.

Key Features

• Active Noise Reduction
• Electronic Talk Through
• Retrofittable

Benefits

The RA195 has noise attenuation exceeding that of some combat vehicle crew (CVC) helmets. Used with the new generation of helmets such as the U.S. advanced combat helmet (ACH) it is a viable alternative to the conventional CVC helmet, offering more ballistic coverage and protection particulalry from roadside blasts.

New earcushion material has been used that leads to reduced fatigue and ultimately better effectiveness.

Applications

The RA195 is ideal for mechanised infantry in tracked AIFVs and APCs.

Overview

The RA315 is the latest HelmsetTM; the 'integration' of communication headset and helmet, suitable for Combat Vehicle Crew applications.

Key Features

• High noise attenuation circa 35 dB with ANR
• Talk-Through
• Choice of soft liner and ballistic shell
• New, improved earcushions
• Retrofitable digital ANR

Benefits

The RA315 may be configured for all the popular intercom systems that support ANR, which leads to improved speech intelligibility and hearing protection for crew, a given in high noise vehicles.

A choice of soft liners offer excellent bump protection and ventilation, and depending on choice of liner, the headset may be configured with or without a neckband spring, which ensures an optimum fit and maximum comfort.

The liner supports a choice of removeable outer ballistic shell that can be removed and stowed when the vehicle is closed down and may be bump only or 'ballistic' with a choice of size, color and rating (400-650, V50 rating).

Appropriate EMC shielding measures ensure protection to radiated field strengths up to 50V/m; important for crew in a head-out situation, close to radio antennae.

Applications

The RA315 may be used in Main Battle Tanks, AFV's and other tracked, high noise vehicles. It is also suitable (without ANR) for ground crew requiring head protection.
