Default Engine hum/buzz

I have a 2014 vert Z51. Lately there is a humming/buzzing noise coming from the engine bay mostly during acceleration. It seems to fade as I drive. I'm going to take it to a Chevy dealer that has a dedicated Corvette repairman, but just want some feedback first. Thank you.

My '17 Stingray 7MT has developed a noticeable medium frequency buzz at 1000-1300 rpm that is engine related, both audible and felt through the frame when the car is stopped and the RPM is increased thru that range... Plan to get it checked at the upcoming oil change.

Just got my 2017 GS back from the dealer and they say that the humming noise in the cabin is normal. It didn't make the noise when it was new. The car has 9,000 miles on it now.

I've replaced two of those at this point, and I would not consider it a hum, but if it sounds like this:
