Audio/Visual (AV) refers to the combination of sound and visual elements to create a cohesive experience. This can include various formats such as films, presentations, and live performances, where both audio and visual components work together to convey information or tell a story. Common AV equipment includes projectors, speakers, and microphones, which enhance the overall impact of the content. In education and entertainment, AV technology plays a crucial role in engaging audiences. For instance, multimedia presentations use images, videos, and sound to make learning more interactive. Similarly, movies and music videos rely on AV elements to evoke emotions and deliver messages effectively.
