What Types of audio visual aids?

Answer 1

Audio-visual is, of course, a combination of two words: audio referring to that which we can hear, and visual referring to that which we can see. The basic frame of reference here limits our application of the term to a speaker and his audience, although they are not necessarily in the physical presence of one another, as in the case of a motion picture or television presentation. The term "aids," used in reference to the speaker, rules out his physical presence (visual) and unrecorded voice (audio). These are the essential elements which make him a speaker, and therefore cannot aid him (his voice cannot aid his voice).Further, the uncontrollable physical surroundings are not audio-visual aids in themselves, although they can have a definite audio or visual effect and should therefore be considered, if possible, when preparing a presentation. These include such things as distracting street noises (a hindrance) or a soundproofed room (an aid); or a beautiful mural behind the speaker (a distraction), purple and orange walls (a hindrance), or a paneled, modern meeting room with indirect lighting (an aid). Handouts, especially maps, charts or tables, make good visual aids. The audience, particularly a large one, can get a finer appreciation of details which cannot be enlarged in a suitable manner. However, the audience is left in a position to continue studying such material, both before and after the speaker refers to it, and thus he cannot "control" its use.We are left, then, with audio-visual aids which the speaker can control, and which are suitable for use with audiences of widely varying sizes.
