AND VERIFIED ANSWER; 100%
CORRECT; 2026- 2027 UPDATE
1 of the most important aspects of designing a computer
work station is what? - correct answer-
keyboard height
--should be from 26-28.5" high and adjustable
*reducing glare also important but usually accommodated
in design of lighting or layout & orientation of workstation
2 interviewers always present: why? - correct
answer- 1. one person to ask questions and the
other to observe and take notes
2. provide a 2nd opinion
2 methods used to measure speech privacy in open offices
- correct answer- 1. articulation class: how
effective a CEILING is in absorbing sound reaching it from
,over LOW PARTITIONS (uses 9' high ceiling and 60" high
partitions)
2. articulation index: measures the performance of ALL
the elements of a particular CONFIGURATION working
TOGETHER, including ceiling absorption, space dividers,
furniture, light fixtures, partitions, background masking
systems, and HVAC sound
--all predicts the intelligibility of speech for a group of
talkers and listeners
--rating between 0 and 1 (1 = no privacy)
--confidential speech = below .05
--normal speech: between .05 and .2
--UNACCEPTABLE level of privacy = .30 and ABOVE
2 ways to improve upholstery safety - correct
answer- 1. treat with chemicals
2. use liner to provide barrier that slows or inhibits the
spread of heat and flame from the fabric to the cushion
3 basic types of adjacency needs - correct answer-
1. people
,2. products (movement of objects facilitated)
3. information
3 performance criteria for foam cushions - correct
answer- 1. density
2. indentation load deflection (ILD): firmness
3. support ratio (ratio of force required to compress foam)
3 primary colors of LIGHT - correct answer-
red, green, and blue
3 primary colors of PIGMENT - correct answer-
yellow, red, and blue
**pigments used in printing = yellow, magenta and cyan
4 major considerations during programming - correct
answer- 1. form (relates to existing conditions of
the space, the physical & psychological environment of
the interior, and the quality of construction)
, 2. function (relates to people using the space, the
activities to be performed there, and the relationship of
spaces to eachother)
3. economy (concerns money)
4. time (describes ideas of the past, present, and future as
they affect the three other areas)
5 important factors to achieve speech privacy in an open-
plan office - correct answer- 1. ceiling must be
highly absorptive ("clear sky" condition = sounds not
reflected)
2. area must include space dividers that reduce the
transmission of sound
3. other surfaces, such as the floor, furniture, windows,
and light fixtures, must be designed or arranged to
minimize sound reflections
4. if possible, activities should be distanced to take
advantage of the normal attenuation of sound with
distance
