Aero Parts Australia is able to supply and install a range of helmet capability upgrades, including hearing protection devices. Some of the options we offer are listed below.
Gentex Wire-Free Communication Earplugs (WCEP) Kit
Providing advanced hearing protection in high noise environments for commercial & military aircrew, and ground crew personnel, the Gentex® Wire-Free Communication Earplugs (WCEP) Kit operates on the principle of Near Field Magnetic Induction (NFMI). The WCEP Kit improves passive noise attenuation, eliminates snag and hot spots associated with earplug wires, and simplifies helmet donning and doffing. The WCEP Kit also provides an ease of use with CBRN gear by eliminating the need to have wires pass through equipment. The WCEP Kit fits in helmets and headset earcups to provide redundant operations to existing equipment speakers.
Gentex Ear Seals featuring Comply™ Foam Technology
Compatible with most Gentex Fixed and Rotary Wing Helmet Systems, the Gentex Ear Seals featuring Comply™ Foam Technology provide increased mission effectiveness by enhancing passive attenuation and reducing fatigue. The Gentex Ear Seals provide improved hearing protection and communications, as well as optimum seal integrity, a key factor in noise blocking and hearing safety.
Active Noise Reduction (ANR) Kit
Active Noise Reduction (ANR) improves sound quality by reducing unwanted noises. Its circuitry reads the incoming sound waves, electronically inverts them in phase, and plays the resulting inverted sound waves through precisely engineered speakers. The ANR system reduces unwanted sound in the range of 50 to 600 Hz, with peak reduction of up to 18db at approximately 200Hz.
