i think i already succumbed to this problem. dint go to a physician yet(what is the point?) but since i did a 500km ride @ high speeds for a continuous long duration.. i have been having ringing in my ears !
since then i have also started wearing ear plugs (industrial grade ones which my friends got me from his workplace). no more can i live in silence.. a noisy world is more silent than silence itself cause the ringing is so annoying. sometimes its so loud it overpowers the other outside noise. it sucks.. after i started having this ringing i googled and faced reality.. wish i had known before..
my parents keep scolding me why my tv/dvd /pc volume is so high.. it just sucks !!
apparently it has more to do with a person's tolerance for higher noise levels and perceptibility to this condition than just the wind noise by itself..
i use a studds bravo helmet.. it cant protect me from wind noise @ 40kmph forget 100kmph..
