3. AEROACOUSTICS
Various features developed by BRP make the helmet agreeably quiet as far as
aeroacoustics are concerned, while providing optimized acoustic feedback
when riding.
Aeroacoustics values may vary according to the type of snowmobile, fairing
design, windshield size, seat position and physical size of the rider.
WARNING
Because of the aeroacoustics optimization of the helmet (and the lower wind
noise inside the helmet that comes with it), your actual speed can be
underestimated. Please do not rely on your sense of hearing to estimate your
speed or to estimate the distance with other vehicles
²
always check it using
your speedometer and the surroundings.
