Odeon vs. Scale Model

See the numerous advantages of a computer model versus a physical scale model:
Question 3D Computer Model
Physical scale model
Typical application. Broad range: schools, atria, concert halls, theatres, multipurpose spaces, churches, ordinary offices, open plan offices, airports, stations etc. Highly critical & demanding acoustic spaces (concert hall, opera houses, theatres etc.).
Approximate price. Low to moderate one time investment. High. Each new model costs extra.
Time needed to create the model. Moderate – several days. Long – 1-2 months.
Time needed to get the results. Moderate – minutes or hours. Long – several weeks.
Level of detail (compared to architectural model). Less detail required – detailed features from architectural model are simplified and replaced with material data. Significantly more complexity required.
Modelling of surface finish materials. Simple – manufacturer’s measurement data entered directly into model. Highly complex and of limited accuracy – sound absorption properties can only be roughly approximated.
Modelling of occupants. Simple –reliable measured absorption data entered to represent audience surfaces. Highly complex – objects must be developed and modelled to represent exact absorption properties of occupants.
Reverberation time. Both T30, T20 and EDT. T30 or EDT cannot be modelled due to uncertainty in sound absorption data.
Room acoustic parameters (SPL, C80, D50, TS, STI, etc.). All parameters available. All mono parameters available (omni-directional microphone required).
Lateral energy measures (JLF, JLFC, LJ). All parameters available Difficult - requires a miniature figure-of-eight microphone
Binaural measures (IACC). All parameters available Difficult - requires a miniature dummy head
Results coverage. Full grid covering every position in audience. A few selected point receivers.
Reliability at high frequencies (modelling of air absorption). Good (air absorption accurately represented in model). Less reliable & problematic (air absorption not included in mode – correction is applied after measurement)
Diffraction, scattering & focusing effects. Approximations applied which are reasonably accurate. Correctly modeled – inherent in model.
Analysis of early reflections – identifying reflection path. Straightforward. Difficult.
Auralisations. Straightforward to create given good quality audio source files. Possible but limited frequency range & limited dynamic range.
