        Nor did I mean to imply that you would. However, I was wondering
if you would end up with your bare ear at the bottom of a flat cylinder
of space, bordered by foam and topped by a resonant surface, that would
act as a wave guide, similar to the way the ear canal itself acts.
        I honestly have no idea whether you'd have to worry about this or
not. If it were me, I would certainly want to know for certain before I
started putting holes in my helmet shell.
