What does in science the 'cross' mean in the warning sounds?
2 answers
Usually it means "danger."
I am confused by your question. The "cross" is a visual symbol, while sounds are auditory.
Also the "cross" would indicate intersecting vertical and horizontal lines. Are you referring to an "X" symbol, where the two intersecting lines are diagonal? To "cross something out" (X) means to eliminate it.
In math and science, "X" typically stands for an unknown, but I don't know how that would be a warning.
I hope this helps a little more. Thanks for asking.
