“…There has been some prior work on sonified graphs, using simulated data sets with different types of graphs (Flowers, Buhman, & Turnage, 1997;Flowers & Hauer, 1992, 1995, whereas other researchers have focused on sonified graphs of complex data sets in research settings (Blattner, Greenberg, & Kamegai, 1990;Lunney & Morrison, 1990;Scaletti & Craig, 1990). However, there has been little research to date in which the use of sound, in addition to visual displays, for real data sets that are used in educational settings has been investigated.…”
