bodily noise

[John Hershey <jhershey@xxxxxxxxxxxxxxx>]

hi auditory people,

does anyone know how the auditory system deals with internal bodily noise, such as cardiovascular, or respiratory (or other)
sources?
 what kind of normal bodily noise levels are present at say the stapes?
is such noise normally suppressed by the auditory nervous system?
i know there are types of tinnitis where extra noise is added by the body, but are there hearing disorders in which normal levels of
bodily noise is not properly attenuated and becomes audible?

thanks,
john
