Pre-construction Performance Predictions
Computer generated and analytical based performance predictions for sound systems
include speech intelligibility, acoustic gain, sound pressure levels, reflection
problems, and acoustic coverage by loudspeaker mapping. Acoustical design predictions
include reverberation times in octave bands, absorption characteristics, geometric
problems, reflection problems, noise transmission levels, and music quality.
Auralization is a new technology that allows listening to room acoustics when the
room exists only in the computer. Projection system predictions include brightness,
seating arrangement, image size, image resolution, viewing distance and viewing angle.
Many human ergonomic issues such as task performance fatigue and physical comfort are
evaluated and considered. Calculations of AC Power requirements and heat generating
levels (in BTU/Hr) for all electrical equipment rooms and projection rooms.
