The use of sound to systematically communicate data has been with us for a long time, and has received considerable research, albeit in a broad range of distinct fields of inquiry. Sonification is uniquely capable of conveying series and patterns, trends and outliers…and effortlessly carries affect and emotion related to those data. And sound-either by itself or in conjunction with visual, tactile, or even olfactory representations-can make data exploration more compelling and more accessible to a broader range of individuals. Nevertheless, (...) sonification and auditory displays still occupy only a sliver of popular mindshare: most people have never thought about using non-speech sound in this manner, even though they are certainly very familiar with other intentional uses of sound to convey status, notifications, and warnings. This article provides a brief history of sonification, introduces terms, quickly surveys a range of examples, and discusses the past, present, and as-yet unrealized future promise of using sound to expand the way we can communicate about data, broaden the use of auditory displays in society, and make science more engaging and more accessible.
