This powerpoint is a lecture and study aide to introduce five listening concepts over a series of lessons. I do not recommend blasting through this one in one day as it is a little thick on information. It is aligned with chapter 4 in Projects in Speech Communication by Perfection Learning but can easily stand alone (my students use the textbooks voluntarily for extra study time at home only, my powerpoints replace required reading). A humorous supplement to listening barriers is available free in my shop. See "Linguistic Barriers to Communication in Advertising."
