Companies offering audio visual (AV) services are responsible for the supply, installation, and operation of AV equipment during an event. AV services usually include the hire of equipment such as microphones, projectors, speakers, and video recording equipment for the duration of an event.

Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions.

AV stands for audio-visual equipment and includes any electronic device used to create audio and visual experiences. Audio and visual equipment covers many things, including microphones, speakers and other audio equipment, video cameras, and display devices.

Audio visual or AV communication brings together audio, visual and interactive media components designed to inform, motivate, persuade or simply entertain target audiences. It relies on stimulating the senses through multimedia for a more immersive and memorable experience compared to traditional static content.
