openPSTD project

This openPSTD project, will provide a software tool, accessible for academic research purposes, which enables to efficiently and in detail compute sound propagation in the built environment. Within the project developments and applications within the PSTD method will be focussed on. The latest 2D version of the openPSTD software, openPSTD v1.1, has been released in july 2015.
In 2016, openPSTD v2 will be published. Download openPSTD v1.1

Introduction

Regardless of our location, we are at all times immersed by a sound environment, which may affect us both positively or negatively. The detailed reproduction of the urban sound environment is essential for analyzing and optimizing it. To date, there is a lack of a detailed 3D acoustic propagation method for this purpose, both due to the computational burden as well as due to the absence of an easy accessible software interface. The openPSTD project, opensource software development of the Pseudo-Spectral Time-Domain method, aims to provide a full-fledged software tool, accessible for academic research purposes, which enables to efficiently and in detail compute urban sound propagation. To achieve this, the computational method behind the tool will be further developed. Within the project, the software tool will also be implemented and applied to studying both reduction of urban noise as well as to support the positive sound environment, the latter especially directed to train the blind in the auditory perception of the environment through auralization.
