For each sound, the percentage distribution of each response category was determined (Fig. 3). The chart shows that doctors classify sounds with varying accuracy. In general, after averaging the responses for all the sounds it can be seen that there is 14.6% CSs, 26.2% PSs, and 59.3% (N), respectively. The most inaccurate diagnoses were statistically significant (chi2(2) = 59.8, p <0.001). Furthermore, if physicians are grouped according to their specialization, it can be seen from the Kruskal-Wallis test that there are statistical differences also between the groups of physicians of different specializations in the category CS (chi2(4) = 16.0 p <0.003). Pair analysis of the differences in answers between groups of physicians with different specializations using post hoc tests with a Holm correction showed that pulmonologists have statistically higher scores than students (p = 0.023) and interns (p = 0.060). In the case of correct answers, there were also statistically significant differences between specializations (chi2(4) = 16.8, p = 0.002). The analysis also showed that statistically students had significantly lower scores than pulmonologists (p = 0.022), pediatricians (p = 0.022) and other specializations (p = 0.073). For incorrect answers, the statistically significant differences (chi2 (4) = 69.9, p <0.001) were related to the lower scores obtained by students and interns.
