bbb12- I know exactly what you are talking about. I too am sensitive to the low freq boom and have bad tinnitus from previous bikes and mild hyperacusis sometimes. Almost had to give up riding. Have a 1200gsa now. Currently wear custom musicians earplugs with 25db etymotic filters., have a Aeroflow touring XL, and a strip a Saeng micro edge on the top edge of the windshield. Also have an Aria Signet Q helmet. Could not ride without these. No ear issues after riding, even very long distance. I am 6'3. Here is my write up on another forum about this. http://www.r1200gs.info/forum/15-acc...indscreen.html
There may be other windshield out there, but I am completely satisfied now.
