A parameter mapping sonification for price differences in market research studies

Differences in prices registered in market research studies are common. Visualization of the price differences is difficult to develop and understand as several attributes are considered by the analysts. An alternative to visualization of the price differences is sonification, a kind of auditory display, in which these attributes and relations are translated into sound. In this paper we present a parameter mapping sonification for differences of prices in market research studies. As a proof of concept, we show results from an implementation of the sonification which creates four samples, one for each category of differences defined in this work. Also we describe its use and its benefits in a real market research environment.
