title: Tempolenses with variable magnification for sonic representation of medical data. Application for cardiac signals.
abstract: The purpose of this study was to develop the tools and the methodology for a systematic analysis of usefulness of adding sonic representation of data, supplementary to visualization. This paper is mainly dedicated various temporal lenses, including the newly developed lenses with variable magnification, proposed as a tool for a better perception of short events combined with a compression of irrelevant intervals. Sonification procedures are also briefly presented. The programs were tested using various cardiac signals: ECG and heart rate HR both in humans and in rats (experimental data). The results, represented by the sound files, were uploaded in an accessible library, which contains both sonic and visual representation of the signals.
