She was right, of course. Wearing hearing aids, your brain cannot "tune out" the background noise you don't want to hear. It therefore sometimes interferes with the stuff you really do want to hear.
However, very good modern hearing aids include noise-cancelling strategies built-in, and also focusable microphones that "zone in" on the person in front of you.
