The International Community for Auditory Display (ICAD) is a multidisciplinary community that includes researchers with backgrounds in music, computer science, psychology, engineering, neuroscience, and the sonic arts. Although this multi-disciplinarity has been beneficial, it has also been the cause of clashes between scientific and artistic research cultures. This paper addresses this divide by proposing design research as a third and complementary approach that is particularly well aligned with the pragmatic and applied nature of the field. The proposal, called sonic information design, is explicitly founded on the design research paradigm. Like other fields of design, sonic information design aspires to make the world a better place, in this case through the use of sound. Design research takes a user-centered approach that includes participatory methods, rapid prototyping, iterative evaluation, situated context, aesthetic considerations, and cultural issues. The results are specific and situated rather than universal and general and may be speculative or provocative, but should provide insights and heuristics that can be reused by others. The strengthening and development of design research in auditory display should lay the path for future commercial applications.
