Previous research has focused on the sonification of a single data series. This paper describes a method of sonifying two data series, and the design of two modes (parallel mode and serial mode) for browsing the graphs. Quantitative evaluation showed that both browsing modes were successful, with the parallel mode being particularly effective. </ABSTRACT></RECORD></RECORDS></XML>
