The second picture, the height is much higher than your home. If the angle is ok, it is a horn.
This is not terrible, the solution: find a convex mirror like the rearview mirror of a big truck online, without a lens! Hang it outside the window, facing the building that forms the horn!
If you still want to ward off evil spirits and make a fortune, hang a gossip gourd of Yin and Yang on the balcony! !
Done, good luck!
