RIA: A Model of Speech Perception in Noise

点击翻译按钮获取中文摘要

9409834 Dorsey This is the first year of a three-year continuing RIA Award to investigate acoustic simulation techniques to improve accuracy of acoustic space evaluation, utilizing theoretical and interactive techniques to indicate specific acoustical effects in a three dimensional computer model. By creating and altering these effects, the surfaces, sound emitters, and geometry will be indirectly modified. The purpose is to have the system cary the burden of searching the design space, allowing the user to focus on the goals of the acoustical design rather than on the details of the model specification. The project benefits from analogous work done in lighting simulation and interactive graphics techniques.
