UPDATED ACTUAL Exam Questions and
CORRECT Answers
Acceptable Viewing Area - CORRECT ANSWER - The area beyond the optimal viewing
area for a display screen demarcated by lines extending outward at 45-degree angles from the
right and left edges of the displayed image, as opposed to the 45-degree angles from the center of
the display image that makes up the optimal viewing area.
Resolution acuity - CORRECT ANSWER - The ability to detect that there are two stimuli,
rather than one, in the visual field. It is measured in terms of the smallest angular separation
between two stimuli that can still be seen as separate.
Recognition acuity - CORRECT ANSWER - The ability to correctly identify a visual
target, as in differentiating between a "G" and a "C." Usually, but not always, it is measured in
terms of the angular dimension of the smallest target that can be discriminated. A clinical eye
chart, where visual acuity testing performed using letters, as is done clinically, is a form of
recognition acuity testing.
Ambient Light - CORRECT ANSWER - Lighting throughout an area that produces
general illumination. REF
Arc-Minute - CORRECT ANSWER - 1/60 of one degree of a 360-degree circle. One
minute of arc is about the smallest angle of vision over which the normal human eye can resolve
an object, under ideal conditions of contrast, brightness, ambient light, and signal-to-noise ratio.
Aspect Ratio - CORRECT ANSWER - The ratio of image width to image height. It can be
expressed as two whole numbers separated by a colon, e.g. 16:9, or by the decimal equivalent of
the implied division,
Building Information Modeling (BIM) - CORRECT ANSWER - data repository for
building design, construction, and maintenance information, used by multiple trades on a single
project. It includes CAD drawings, as well as information such as bid and contract documents,
, Bills of Materials (BOMs), timelines, specifications, price lists, installation and maintenance
guides, cable lists, and cable label guidelines. ref
Binocular Vision - CORRECT ANSWER - area where the visual field of two individual
eyes overlaps. In this area, the central field is of greater magnitude than that possible by each eye
separately. You can recognize words and symbols and interpret depth perception in this field.
The binocular field is about 60° in each direction. ref
Boundary Microphone - CORRECT ANSWER - relies on reflected sound from a
surrounding surface. A boundary microphone sits directly on a table or surface. They are also
called "surface mount microphones."
Candela - CORRECT ANSWER - luminous intensity of a source that emits
monochromatic radiation of frequency 540 × 1012 hertz, and has a radiant intensity in that
direction of 1 ⁄ 683 watt per steradian. The candela has replaced the candlepower standard.
Casework - CORRECT ANSWER - similar to furniture, with the distinction that casework
is built into the room. Casework includes such items as cabinets, credenzas, benches, and
podiums.
Circulation Space - CORRECT ANSWER - The amount of area a person needs to turn
around without disturbing other people. According to Fruin, this area is 10 to 13 square feet, or
0.93 to 1.21 square meters per person. ref
Closest Viewer - CORRECT ANSWER - Viewer positioned at the shortest distance from
the screen as defined by the viewing area.
Clue - CORRECT ANSWER - A visual cue that allows a viewer to fill in the elements that
are not easily viewable.
Computer-Aided Design (CAD) - CORRECT ANSWER - software used to create digital
models or drawings. These models can be in the form of 2-D multiview drawings or as 3-D
models, which are used for a wide variety of purposes. In the AV industry, CAD is used in the
