Just 18mph of wind is enough to cause permanent hearing damage. Windshields and helmets don't block enough of the air (the rider needs some air ventilation for defogging in cold weather and cooling in hot weather.)

If you try to fully seal the helmet you cause measurable oxygen deprivation. https://youtu.be/x_ej8sehs8k?si=9LtvP0TfhQzgNDVM
