David - you must be a musician
Few people can differentiate between the various sounds their ears are assaulted with in a car, much less music (although in the 911...it's the same thing).
I can hear valve train noise - since when I adjusted my valves I did a poor job of it and there was some train noise afterwards. I can certainly hear the muffler/exhaust noise...and I have heard my fan belt on occasion, but the fan itself is mostly just background.
Mostly I hear the engine breathing - I hear a little intake noise, but mostly exhaust and general crank sound. I hear the transmission a bit, too. Luckily I don't often hear it grind, but when it does, it means I just nicked reverse coming out of fifth.
I hear a LOT of wind noise! I have a Targa. A lot of it is caused by the top itself, but there's also some that is the air going over the metal trim peices on the windshield seal. I need to call the glass company that did my windshield about that.
Sometimes I hear the CD player. Not often though, unless I turn it way up....
