The RADICAL project is funded by a Leverhulme Trust Research Project Grant (RPG-2020-113).

The project commenced on 11 January, 2021 and will run until March 2024.


Sonification represents (signifies) data and relationships between data through sound (like a Geiger counter for data) but is still not widely accepted. Understanding of the role played by embodied perception, spatial considerations, and aesthetics in our listening to, and perception of, sonification is very limited. These aspects of sonification cannot be addressed except through an interdisciplinary approach, and this project draws together proven experts in computer science, sonification, listening and perception, ethnography, music composition, and aesthetics to foster a fundamentally new understanding from which to derive concrete guidelines for better and more successful sonification design.

Sonification is the use of non-speech audio to communicate data and data relations but it lacks the general acceptance of information visualisation despite great potential, especially in continuous monitoring situations in which it is impractical to watch a computer screen for long periods. The ways in which people listen to sonifications and make meaning of the sounds they hear is still not well studied and current approaches to sonification research have tended to design sonifications for narrow use cases with results and design heuristics that are not transferable and of mixed success. Furthermore, considerations of the role of aesthetics in sonification listening are very restricted, typically being confined to questions of how pleasant the audio sounds. It is now widely accepted that the act of listening involves embodied perception. That is, making sense of and responding to sound involve not only our ears but are shaped by aspects of our entire physical body as well as our interactions with the space in which listening takes place. We will conduct a comprehensive study of sonification making and listening to form a fundamental understanding of the relationships between sonifications, their designers, and their listeners. The interdisciplinary nature of the project team will enable us to develop a new theory of sonification listening and to derive an aesthetics of sonification which, up till now, has no accepted definition. These outcomes will be important in formulating a new framework for successful sonification design. This in turn, has the potential to help sonification to become more widely used.


An important part of this project is the role of spatialised audio and we will be making much use of Northumbria’s IKO icosahedral loudspeaker.
