Aluminium surface on right side of trackpad sounds hollow (Magic Keyboard Pro 11 2024 M4)

Perhaps stupid question: The aluminum surface on the right side of the trackpad sounds completely hollow when I tap on it with my fingernail, while the surface on the left side sounds solid. Is it the same for you?

same. tested on an 11 and 13 M4 Magic Keyboard, both sound more hollow on the right.
it sounds more hollow on the 11 keyboard though, but there is still a difference in sound on the 13.
