text: has anyone ever had this high pitched ringing in their ears for no apperent reason? just at random times in my day, i'll hear a high pitched ringing, nothing ever seems related from one incident to another.  anyone have any idea what this phanomanon is? yes, i have that frequently, and it can sometimes be very annoying.  the following link has some great information on "tinnitus" or ringing of the ears.  hope this helps. http://www.ata.org/about_tinnitus/consumer/faq.html#2
