audio-visual
The term audio-visual may refer to works with both a sound and a visual component, the production or use of such works, or the equipment involved in presenting such works. Movies and television shows are examples of audiovisual presentations.
Business presentations are also usually audio-visual. In a typical presentation, the presenter provides the audio by speaking, and supplements it with a series of images projected onto a screen, either from a slide projector, or from a computer connected to a digital projector using software such as PowerPoint.
