Audio- visual aids are instructional devices which are used to communicate messages more effectively through sound and visuals.
Audio-visual aids help in stimulating the sensory organs like ears and eyes and facilitate quick comprehension of the message by the audience. These may be used for literate as well as for illiterate people.
What is audio?
Audio means what we hear. The five senses audio, visual, touch, smell and taste plays an important role in communicating message. Hearing plays an important role in receiving and sending a message effectively. The most basic form of communication is oral and face to face contact. Hearing plays an important role in oral-face to face communication. In recent days due to the invention of modern gadgets like radio, tape recorder, public address system telephones and mobile phones the type of communication is more of an indirect type as the individuals do not face each other. People in such situations communicate without coming into close proximity.

What are Audio-visual aids?
Audio-visual aids or devices or technological media or learning devices are added devices that help the teacher to clarify, establish, co-relate and co-ordinate accurate concepts, interpretations and appreciations and enable the learner to make learning more concrete, effective, interesting, inspirational, meaningful and vivid.
Or in other words
Audio-visual aids are used to improve teaching, i.e. to increase the concreteness, clarity and effectiveness of the ideas and skills being transferred. They enable the audience to LOOK, LISTEN and LEARN (by doing); to learn faster, to learn more, to learn thoroughly and to remember longer.
According to an old Chinese proverb the importance of audio-visual aids is indicated by the saying that “if I hear I forget, if I see I remember, if I do I know.”
The audio-visual aids help in completing the triangular process of learning, motivation, clarification-stimulation.
The aim of teaching with technological media is clearing the channel between the learner and the things that are worth learning. The basic assumption underlying Audio-Visual Aids is that learning and clear understanding-stems from sense of experience. The teacher must ‘show’ as well as ‘tell’.
Audio –Visual aids provide significant gains in informational learning, retention, recall, thinking, reasoning, activity, interest, imagination, better assimilation, personal growth and development. The aids are the stimuli for learning ‘why’, ‘how’, ‘when’ and ‘where’. The ‘hard to understand principles are usually made clear by the intelligent use of skillfully designed instructional aids.
It must be remembered that Audio-visual aids can only supplement the teacher but can never supplant the teacher.
