Audiovisual refers to materials or presentations that combine both sound and visual elements. This can include videos, films, slideshows, and multimedia presentations that use images, graphics, and audio to convey information or tell a story. The integration of these two senses enhances the audience's understanding and engagement. In education and entertainment, audiovisual tools are widely used to create more dynamic experiences. For example, educational videos can help students grasp complex concepts, while movies use audiovisual techniques to evoke emotions and tell narratives. Overall, audiovisual content plays a significant role in communication and learning.
