Geezer Can’t Hear the Question!!!

Have you ever gone to a lecture where the speaker takes questions from  the audience? Usually the speaker has a mike; and, usually the questioner does not. So, if you are old and deaf, like me, you get the answer, but not the question. There you are floundering about in the netherworld of the hearing impaired.

Why aren’t public speakers aware of their audience? I can understand if they are speaking to a general audience, but if the audience is made up mostly of people my age, why can’t they repeat the question; or, at least summarize it?
