Therefore, we hypothesized that a simplified diagram of lung sounds would improve lung auscultation ability by allowing the learner to visualize lung sounds without special devices. However, spectrograms may not be available in all institutions, and it is difficult to visualize them with a normal personal stethoscope. It is useful to learn the characteristics of lung sounds the use of spectrograms can aid medical students in diagnosing lung sounds and identifying abnormal lung sounds. In the spectrogram, intermittent rales are represented by short vertical lines and continuous rales are represented by horizontal lines. Lung sounds have been visualized by spectrograms, which have been published in textbooks, with the vertical axis representing sound pitch and the horizontal axis representing time. Therefore, the addition of visual information regarding lung sounds may improve lung auscultation learning. The auscultation ability of some lung sounds has been improved by illustrating the mechanism that produces abnormal lung sounds. In textbooks, lung sounds are often presented in simplified diagrams. The reason for this result could be that the participants were asked to choose the relevant lung sounds from a list of options, while the heart sounds were answered graphically.

Ltd., Kyoto, Japan) and observed an improvement in the ability of auscultation of heart sounds but no change in that of lung sounds.

examined the effects of simulator-based education on lung sounds and heart sounds (Cardiology patient simulator “K Plus” training system, Model #11257–159, Kyoto Kagaku Co. These simulators can improve learner confidence and knowledge of lung sound auscultation. The skills of lung auscultation have been taught using simulators, in addition to textbooks and audio sources.

However, effective education on how to perform lung auscultation has not been developed. Even for pulmonary auscultation, web-based materials and computer applications on pulmonary auscultation are available. However, the number of appropriate teaching materials is limited. Moreover, in recent years, video-sharing sites on the Internet have made it possible to listen to lung sounds. Recent advances in digital stethoscopes have made it possible to record lung sounds and share them among multiple medical professionals, as well as to analyze lung sounds automatically, perform auscultation wirelessly, and provide telemedicine. Therefore, medical students need more effective education programs on lung auscultation to improve their skills continuously. This finding suggests that physicians may not have better lung auscultation skills than medical students. In studies comparing the auscultation skills of medical students and physicians, there was no difference in skill, except for pulmonologists. However, it is not easy to accurately listen to lung sounds and assess respiratory conditions. Regarding clinical respiratory examination skills, auscultation of lung sounds is often learned during medical school. Lung auscultation is a useful non-invasive method for clinical reasoning and identifying a respiratory condition using only a stethoscope. Lung auscultation is a fundamental part of physical examination it is routinely performed by doctors and other medical professionals alike. The Wilcoxon signed-rank test and analysis of covariance were used to compare the answers to the questionnaire about confidence in lung auscultation and the scores of the lung auscultation tests before and after the training. We compared the answers in the questionnaire and the test scores between the visualization group and students who only attended the lecture (control group, n = 30). They also took a lung auscultation test with the simulator at the beginning of CC (pre-test) and on the last day of the third week (post-test) (maximum score: 25). All students answered questions on their self-efficacy regarding lung auscultation before and after four weeks of CC. Among them, 35 (visualization group) received additional training wherein they were asked to mentally visualize lung sounds using a graphical visualized lung sounds diagram as an example. Overall, 65 students attended a lecture on lung auscultation featuring a simulator (Mr. The study period was December 2020–November 2021.
