I don't know if those are the same or similar to a bruit?
For a long time I had a whooshing/pulse like sound that I could hear inside my head, very annoying... mine was the worst during times of severe spasms.
Some nights it was like an old time train running thru my head chug a chug all night long..
My chiro was the one that actually told me the name of those sounds.
Luckily he was able to resolve those bad spasms, took about 2 months and then my top ribs were stuck in a raised position from the spasms..
An adv PT guy found that and dropped them down, and then chiro followed up after as they tried to raise every once in awhile.
But all has been pretty good for about 4 years now.
