Chapter 6 Conclusion

6.1. Simulation System
We developed a system that computes independent physical factors in a sound space from building drawings at the design stage and can actually estimate the factors at each seat.

6.2. Diagnostic System for Sound Field in the Room
We built a system to diagnose the sound field at each seat in the actual building and a model based on a functional model of the human sense of hearing (cerebral system). We clarified the usefulness of the system by comparing the results 6.1 obtained at the design stage with those from our actual diagnosis.

6.3. Seat Selection System
We built a seat selection system to find the optimum location for each auditory sense and developed a system that indicates the range of seats for which different individuals will have the highest preference.

6.4. Diagnostic System for Environmental Noise
A system for measuring temporal and spatial factors in a noise environment was developed. This provided additional information about the physical characteristics of noise sources, suggesting its usefulness for making a mental evaluation based on distinctions between noise sources.

This development should lead to a better fundamental understanding of 1) the processes for designing and evaluating indoor sound fields and 2) individual sensitivities - for example the size (loudness) and height (a pace) of the sound, three elements of the tone, unpleasantness, spatial sense, and individual sensitivity in such cases as a mental time sense.
