Fig. 9. The percentage distribution of responses marked for the classes (a) normal bronchial sound; (b) normal lung sound; (c) louder breath sound. The light grey bar depicts the correct answer, n is the number of this kind in the survey.
In the case of the juxtaposition of inspiratory and expiratory wheezes (Fig. 10), it can be noticed that they are generally recognized correctly, i.e. the percentage of those answers is the highest, so those are the most likely answers. Most often they were confused, i.e. inspiratory wheezes were confused with expiratory wheezes and vice versa. In addition, only in the case of inspiratory wheezes, was rhonchi marked as an additional class. This means that in the case of evaluating previously recorded sounds physicians have difficulty identifying the inspiratory and expiratory phases.
