Typically all transformers make some noise when operating. That being said what brand transformer did you buy? Some cheaper transformers can be noisy. Without the transformer mounted to the panel is it still “buzzing”. Often times when placed in the knockout it can vibrate on the panel itself. Make sure the set screw is also tight and firmly in the knockout.

The buzzing is still there, even with a second transformer change and the doorbell itself. You can see the chime vibrating up and down.

If you have a multi meter can you measure the voltage at the chime? I am guessing this is a low voltage issue with the transformer.
