Audiovisual Equipment

Recorded sound can enhance a display, as long as it does not compete with a neighboring booth. If a booming public-address system is used, unhappy inhabitants of neighboring exhibits may complain—or else in­crease their own volume. If you incorporate sound in a slide-tape, film-and-tape, or video presentation, the visual image will tend to draw the audience in closer, so that sound can be heard at a reasonable volume. Hoods and panels keep sound under control.

If you use film loops or video, you may also need to plan for a hood, panel, or canopy to shield the back-projection screen from overhead lights and spotlights in neighboring displays. If you plan to make ex­tensive use of audio-visual materials, check in advance with show coor­dinators to make sure there are adequate electrical outlets and sufficient power.
