Confusing and Confused can be used to describe the same nouns. I have looked up the definitions of both of the terms only to find that they are indistinguishable. In Oxford Learner's Dictionary, confusing defines as difficult to understand; not clear. Confused defines as not clear or easy to understand. You can use either confused or confusing in the following sentence.
Any difference in meaning?
I am quite aware of words that end with -ed to talk about a person's feelings and -ing to talk about the situation or thing that cause a person's feelings.
But it looks like you can say "confused speech" or "confused information", which I only know that to describe these nouns we use "confusing" not "confused". We can say "this is a confusing situation" or "this is a confused situation", both of which can mean that the situation is unclear. I don't know if there is a difference here.
