Evaluation of 3D Positioned Sound in Multimodal Scenarios

This Ph.D. study has dealt with different binaural methods for implementing 3D sound in selected multimodal applications, with the purpose of evaluating the feasibility of using 3D sound in these applications.
The thesis dealt with a teleconference application in which one person is not physically present
but interacts with the other meeting members using different virtual reality technologies.

The thesis also dealt with a 3D sound system in trucks. it was investigated if 3D-sound could be used to give the truck driver an audible and lifelike experience of the cyclists’ position, in relation to the truck, so the truck driver had an intuitive awareness of the cyclist’s position.

It was concluded that the implementation of the 3D sound in the truck improved the situational awareness of the truck driver, and could therefore be deemed feasible for the application. Implementations of 3D
sound in teleconference application also seemed to have an effect as long as the task was sufficient challenging.
