Fig. (8) Exemplary output of our database prototype. The uploaded pattern represents the heart sound in case of aortic valve stenosis after wavelet transformation as shown in Fig. (7). Links to articles with most similar stored patterns are listened first. The links are accompanied by structured information for test purposes. The distance d quantifies the deviation to the uploaded pattern, the first link points to an article with the same sound like the uploaded one, therefore the distance is zero.
