Active Noise Reduction

The Alpha Eagle helmet is ideally suited for commercial helicopters and can be equipped with our Active Noise Reduction (ANR) system. The ANR modules replace the standard earphones and a new downlead is installed. The original passive performance of the helmet as well as the fit of the helmet are unaffected by the installation of the ANR system. If the ANR system is turned off or the power to the system is interrupted, for example by batteries running down then the system will revert to a communication only failsafe and passive protection level of the standard helmet. The system is available with coiled or straight cables and a quality 8 Pin Lemo connector. The system can be battery powered or powered directly from the aircraft. You can simply change from aircraft power to battery, just by plugging into our rechargeable battery box.

The system is available to suit most aircraft intercoms with (USA Low impedance) 19 ohm, UK NATO) 150ohm or (Civil Spec and police ASU) 600 ohm speakers. Our system is fitted to all UK Police Air Support Helicopters, and is also available with the standard Bose 6 pin plug so you can plug directly into a helicopter fitted with the BOSE installed kit. We recommend that Gel Ear Pads are fitted during the install as they give a better seal around the ear and enhance the performance of the ANR.

Call our Sales Team on +44 (0) 1273 234181 if you are interested in having ANR fitted to your Alpha helmet.
