They did something similar to the Avata 1. It got discounted quite a lot, then some rumors here and there about the Avata 2 and then BOOM! Avata 2 came out.
Literally what's happening with the Air 3.
OP any updates?
I did ask some Air 3 users and no they didn't have the buzzing noise. Also it was also a reported issue for other Air variants:

The above was poster in 2021, and yes there were several others as well:
