Database of City Sound Spaces and its Intelligent Applications

Abstract

Limitation of traditional computer tools about city sound-planning is obvious. Some of them depend on a geographic information system to represent sound environment. Some of them have been designed to evaluate the propagation of traffic noise. Both cannot provide practical sound-planning references for the real projects. For improvement, a new database seems necessary first. Benefitting from the researches about how neighboring sound spaces interact on each other, we designed two kinds of data forms to integrate all useful data into this database. Sound event form is considered as the basic unit to compose a sound space. Sound space form is used to represent each sound space. With the help of this database, complicated sound spaces can be represented effectively. Furthermore, many intelligent applications about city sound-planning can be realized. For example, users can diagnose the sound-planning of their own project by making inquiry in this database.
