My contention has always been that most of it is too difficult to hear. It has to be measured with a scan tool.To that, I would say no. There was no significant difference in noise, that would cause for alarm. Is there noise coming from the engine bay, yes, but as you'd expect for a 22' vehicle with close to 60k miles on it, that's the kind of wear and tear you'd expect to happen.
Hope that answers your question.
Turning off the air and radio and putting the windows down to listen ain't good enough, been there, done that, with the scan tool running.
