Audio-visual equipment refers to devices that combine sound and visual elements to enhance presentations, entertainment, or communication. Common examples include projectors, microphones, and speakers. These tools are widely used in settings like classrooms, conferences, and movie theaters to create engaging experiences for audiences. In addition to traditional uses, audio-visual equipment has become essential for video conferencing and streaming services. With the rise of remote work and online learning, tools like webcams and audio mixers help people connect and share information effectively. This technology makes it easier to communicate ideas and collaborate, regardless of physical distance.
