Then to presents what other scientists studied in this filed and what they achieved. The needs of employing new tool “system” to help the architect in designing theaters through acoustical aspects. -Collect available data about the architectural and acoustical date that have positive direct correlation. -Arrange these data depending on the priority of its effect on the acoustical environment. -Draw mapping to the architect to make it easy to read the acoustical requirements for the theater. Building the knowledge base of the system introduce the great effect of the computer as a tool that can help in the architecture field in general, and in architectural acoustics in specific. Then to present new techniques that can be used in developing the new system in the next chapter. Choosing ES as a tool to build the system. follow the right procedures in building ES, then to investigate of the possibility of developing a new ES (DTTAA) that can help the architect in the first stage of designing theaters with consideration of RT requirements. Preparing a prototype of the suggested system summarize all results of the previous 3 chapters, then introducing recommendations and future studies to complete what started in this research.
