It always gets my goat when someone says they're "quiet as human conversation". Phooey!
What they don't tell you is that human conversation is measured at three feet away face-on, while the "same" noise level from a Honda is measured at a minimum 25 feet, and with the muffler pointed away from the meter.
Your wife is probably just finally really hearing the blasted things.
I'm sorry you don't understand sound measurement, even more so that you are posting like you do.
