Noise auralisation challenges in web and augmented reality applications

Auralisation of the machinery noise is becoming important with the development and availability of advanced noise modeling tools. With the auralisation, it is possible to enhance or replace the prototype or mock-up construction. For this purpose, we have developed real-time auralisation platforms for welding noise, engine noise and rock crushing station noise, among the others. The developed auralisation tools operate as stand-alone systems and also as web tools. Converting the stand-alone models to web applications is not a straightforward task, and several issues must be taken into an account. The other expansion path is to connect audible models to virtual or augmented reality environments. We simultaneously visualise and auralise 3D sound field of machinery noise with the combination of the audible model in a laptop computer and visualisation with a tablet PC. In this way we demonstrate the future of noise-related product prototyping and development.
