In the past, acoustical consultants could only try to convince the client/architect that with calculations and geometrical plots they could create an acoustically superb space. Now, by modeling the significant acoustical parameters of a design, we can preview a proposed acoustical solution and it is possible to identify the objective parameters that correspond to certain subjective reactions experienced by listeners. The results of a simulation can be presented not only for the eyes but also for the ears. This document explains the basics behind acoustic computer simulation. It includes case studies that analyze and validate numerical parameters and create a sound simulation of a space that allows the listener to subjectively "grade" the acoustical qualities. It includes details on how human hearing uses several techniques to localize sound sources, how we can simulate factors that influence human auditory perception with computer software, and how we can reproduce the listening experience for a space that has not been built. The simulation techniques offer the possibility to use the ears and listen to the acoustics of a room during the design process. Several acoustic problems can be detected by the ears, whereas they may be difficult to express with a parameter that can only be calculated. Using these tools the acoustician can communicate the acoustic consequences of a design to the client/architect effectively. This technique can be used very early in the project to achieve exceptional results.
