Ventilated Tank Helmet
The helmet incorporates mountings for a headset, which is designed to give good noise protection and to provide good communications even under high noise conditions. The standard headset is fitted with a boom-mounted, high quality, noise-cancelling microphone, which provides discrimination between close speech and high levels of ambient noise. Optional types of boom microphone are available, miniature moving coil, magnetic and an electret type; a throat microphone is also available. If required, an optional Voice Operated Switch can be incorporated in the headset to further reduce the noise exposure in ‘Live Intercom’ situations.
