Traditional methods for measuring the health of the U.S. economy—new residential construction, manufacturing trade inventory and sales, residential sales, for example—do not often provide a full picture of growth or decline. A number of financial firms have turned to offbeat indicators to fill in the gaps. Convergex is one of them and has provided Foreign Affairs with the numbers to produce a similarly offbeat presentation of that data: sound. Penn State professor Mark Ballora, who in his TedX talk implored visualizers to "open their ears to data," explained that "we tend to be visually oriented and to underappreciate the contributions other senses give us." In fact, Ballora notes that the ears are better at "picking up patterns and dynamic changes." Here, Matthew Kenney, who works with Ballora at Penn State helps us to listen to the economy with the sonifications of three unusual economic indicators: coin sales, truck inventory, and inflation as measured by the rising prices of bacon cheeseburger ingredients.
