Did you remember to unselect the portion you used to get the noise profile - otherwise all you'll do is reduce the noise in the selection (I usually come out of noise reduction (when I click Get Profile), press the double-left-arrow to move the cursor to the start and then do Noise Removal again to remove the noise (Or select repeat Noise Removal - I think that does the removal without changing any parameters).

I use it all the time when listening to old blues recording when I'm looking for lyrics. The setting I've got are: noise removal 12; Sensitivity 0.0; Smoothing frequency 150; Attack/decay 0.15. And they're usually fine for what I want. Occasionally I up the noise removal to 30 or 40 on really bad recordings.

(I'm currently running 1.3.13-beta under Ubuntu; but I don't think the NR parameters have changed in the last several versions).
