CEP Aviation Custom Adapters

The CEP Aviation Custom Adapters main advantage is that it prevents unwanted sound from entering the ear canal from the outside of the helmet but permits communication signals to enter the ear without attenuation through the earplug.

The ANR for aviation helmets is composed of electronic components that transduce, condition, and reverse the phase of the “residual” noise that penetrates the headset’s ear cups and then introduce this “antinoise” inside the earcup space in a phase-inverted time relationship with the residual noise to affect its cancellation. This technology results in attenuated sound levels to the listener, more so for low-frequency signals than for high-frequency signals. This result is an advantage of ANR when it is combined with the typical flight helmet because ANR compensates for the lack of low-frequency attenuation of the flight helmet.
