According to AVIXA standards, what is the maximum distance a viewer should sit from a display, expressed as a multiple of screen height?
Answer: 6 times the screen height
AVIXA's DISCAS standard recommends a maximum viewing distance of 6 times the screen height for HD content to preserve image detail.
What does measuring RT60 during an AV site survey tell you about a space?
Answer: How long it takes for sound to decay by 60 dB, indicating the room's reverberation characteristics
RT60 measures sound decay time, directly affecting speech intelligibility and determining whether acoustic treatment is needed.
What is the maximum horizontal off-axis viewing angle from a display's centerline that AVIXA recommends for acceptable image quality?
Answer: 45 degrees
AVIXA standards set a maximum horizontal off-axis viewing angle of 45° from the display centerline before image quality degrades unacceptably.
When surveying a room with a coffered ceiling for speaker placement, what is the primary acoustic concern?
Answer: Uneven acoustic coverage due to recessed cavities creating dead spots and additional reflections
Coffered ceiling recesses create uneven sound distribution and additional reflections that complicate speaker coverage planning.
What is throw ratio, and why is it measured during an AV site survey?
Answer: The ratio of projector distance to image width, used to determine projector placement
Throw ratio (distance ÷ image width) determines how far a projector must be placed from the screen to achieve the desired image size.
A conference room has east-facing windows that admit direct sunlight during 9 AM meetings. What is the best solution to document in the survey?
Answer: Specify motorized blackout shades and orient the primary display to minimize glare paths
Motorized blackout shades control light at its source while preserving window function, and display orientation adjustment minimizes glare on participants.
When surveying a tiered auditorium for a front-projection system, what dimension most critically constrains screen size selection?
Answer: The floor-to-ceiling height at the projection screen wall
The ceiling height at the projection wall establishes the maximum screen height, which in turn determines usable screen size and projector requirements.
