Utilizing Virtual Reality for Simulating the Auditory Perception In Architectural Designed Spaces

Utami, Sentagi S / Navvab, Mojtaba

Rapid development in computer technology has triggered the emergence of new methods and techniques for room acoustics simulations. However, the auditory representation of a simulated space is usually given less attention than the visual representation. This paper demonstrates an approach for simulating the auditory perception in architectural spaces based on auralization, utilizing an immersive virtual computer-generated environment. Detail steps in this approach are provided including the process to transform two-dimensional drawings into room acoustics simulation. Change in the auditory perceptions in an architectural space with variety of design implementations, were recognized. Spatial perception of distance and orientation were explored while architectural elements and acoustical properties of the surfaces were changed with the goal to obtain the anticipated room acoustics quality. While multidimensional virtual environment provides the ability to investigate the visual and auditory perception simultaneously, this approach provides the ability to present computer generated spaces, synthesize auditory events and have users experiencing the architectural design impact. Evaluation of the room acoustics, given the architectural design options can be done at any stage of the design process.
