What's the difference between a bruit and a thrill?

In particular, when talking about dialysis patients, and assessing their fistula. Is it that bruit is the sound, and thrill is the feeling of it?

 

[Anticieeeee]

The way we were taught to remember it is that you 'feel a thrill'. So, you hear a bruit.
That's how I kept it apart for years.
