Acoustic simulation and auralization in architectural design practices

Abstract

This paper is dedicated to predictive relationships between space design and acoustic performance in architectural practice through auraliza-tion. With such a relationship, design alternatives can be evaluated subjectively, as well as objectively, without being constructed. In traditional practice, designers rely on vague experiences and rough estimates to predict acoustic effects while designing architectural spaces. Acoustic analysis and predication are seen as a luxury remedy and only affordable in large-scale theaters and concert halls. The recent available personal-computer-based auralization technologies brought the possibility of applying the latest science and art of architectural acoustics into design practices. Case studies presented in this paper illustrate that the auralization technology makes it possible for potential occupants as well as designers to evaluate the acoustic performance of a design by hearing it directly before a decision to build is made. They also illustrate that the auralization is a powerful tool for the general public to uncover everyday acoustic problems in common building types that have been constantly harming their well being and would otherwise be undetected. Furthermore, they demonstrate that auralization is an effective means to evaluate noise effect on subjective perception where the noise effect is signal context dependent.
