Re: SPL of pulse

[Thomas G Brennan <g_brennantg@xxxxxxxxxxxxxxx>]

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.
