All motorized aircraft make a lot more noise than pilots and passengers imagine and you need a helmet that will minimize noise as much as possible. You protect your hearing and ensure that communications between the pilot and passengers are clear and that air traffic control can be maintained. It is an essential requirement for a safe flight.
Aviation helmets with the highest level of noise attenuation use Active Noise Reduction (ANR), in which the helmet generates a sound wave of the same amplitude but with an inverted phase compared to that of the background noise. who cancels it. This results in maximum attenuation of the cockpit noise.
For my part, I chose the Bose A20 aviation helmet, a pioneer in its field, offers you an unprecedented combination of active noise reduction, comfort and clarity of communications. So you can focus on what really matters : your flight.
