Abstract:
This thesis is dealing with the architectural design of lecture theaters, based on their functional aspects and human comfort with emphasis on the acoustical demands.

Models have long been apart of the architectural design served in both the perceptive and technologic developments of buildings and spaces. Physical models, however, can be costly and in some cases difficult to implement. Computer models prove to be powerful, easy to build and money and time saving. There are two main methods of computer modeling, ray tracing method and source images methods. Both have been implemented successfully, but the later one is more accurate and easier to use by an architect with little knowledge of acoustics and computers.

The study has experienced the source image method by comparing the results of computer simulation of noise distribution with the results of measurement field of the same room.

The results confirmed the accuracy of that method that was used successfully to simulate sound energy distribution in lecture theaters and to choose the best location of furniture and sound sources.

The results of this thesis could be considered as a major development in acoustical design field by using computer simulations.
