The main objective of the design was to increase the organ's accessibility for the general public and enhance their experience when visiting the Studio Acusticum concert hall in Piteå, Sweden.

Designing appropriate auditory warnings is a well-known challenge. The present work focuses on a new type of auditory warning for within-vehicle use, combining a signal that conveys urgency information with a signal that conveys more detailed information about the urgent event. In the study, three concepts of "combined warnings" are compared. The concepts(More)
This paper presents a simulator study that evaluates four auditory displays to assist commercial drivers in lane changing situations. More specifically, the displays warned the drivers about vehicles in the adjacent lane. Three displays utilized different variants of graded auditory warnings (early and late signals) while one display contained a(More)
