Kevin, the blood sounds you're hearing differ from one person to another and will differ according to blood pressure. In fact, this can be a form of pulsitile tinnitus in itself. There isn't an easy answer to your question although OAA or some other internal measure may help. An audiologist who works with tinnitus should be able to help you determin the level of your tinnitus as well as the frequency components involved. as to your question concerning individuals with hearing loss still being able to "hear" this sound, it has been reported to me that they still hear it. I suspect there is some action of bone conduction complicating this in the unilaterally deafened person. There is also a vibratory component to this so the action in these people may actually be strictly vibratory, or at least largely so. Tom Tom Brennan, CCC-A/SLP, RHD web page web master web master
