What comes to mind immediatly, I believe, is Tinnitus... Pulsatile tinnitus can have numerous causes, including narrowing of the internal carotid artery. It results in your 'hearing your heart' (although there can be many causes of pulsatile tinnitus, btw). High-pitched tinnitus is also quite a common type of tinnitus. Whether Cage thought it was music is another question... I know that when i enter our sound room, I hear a high frequency noise, esp during an experiment, late at night.
