Terribly.
Of note, these are still used in MRI machines. Presumably because of the whole 'no metal in the giant magnetic field' thing.

For a pretty solid and easy to understand primer (101 level), check out Hank Green in Crash Course Anatomy & Physiology - Respiratory System Part 1. Then go back and watch the rest of the series because it's great.
Or even better, start with the series he does on Physics, then Chemistry, then Biology, then A&P and finally Psychology so you have the building blocks in the right order!

Haha - yeah, my experience was similar. There was music, but I was in no position to assess the sound quality other than to think 'that sounds tinny' as they shoved my head into the loud clanking machine.
