Lost some of my speech range frequencies in the Navy's enginerooms, and when I went to a open face helmet with a shield and ears covered, damn near can't hear the vario now. In the process of of drilling holes in the ear area of the helmet, and then bonding on small "scoops" on the exterior of the helmet, to act as air intakes AND reflectors (ears) for the sound. What are advertised as "vents" on most motorcycle helmets don't do SH*T at hang-gliding speeds, so the extra air won't bother me a bit.
