Title: The Effect of White Noise on the Ability of a Medical Student to Recognise Correctly Adventitious Lung Sound. Methodology: Randomized, controlled trial, blind study. Study Duration: The estimated duration for the main protocol (e.g., from the start of screening to the last subject processed and finishing the study) is approximately 4 weeks. Study Centre: Lithuanian University of Health Sciences (LSMU) and Kaunas Hospital of LSMU. Objectives: Primary Objective: To evaluate the accuracy of second-year and third-year medical students in correctly identifying pathological and nonpathological lung sounds under different white noise levels. Number of Subjects: A group of 104 students will be exposed (EXP) to learning pathological and nonpathological sounds for 3 days. After 3 days students will take 3 tests with different levels of white noise pollution added ( signal-to-noise ratio (SNR) 20, 40 and none added). Diagnosis and Main Inclusion Criteria: Inclusion Criteria: male and female second and third-year LSMU students; 18-40 years old; in any distribution. Consent and compliance with all aspects of the study protocol, and methods, providing data during follow-up contact. Please, see the methods section for a full list of inclusion criteria. Exclusion Criteria: deafness; age over 40; conditions that prevent the student from using earphones. Please, see the methods section for a full list of exclusion criteria. Regimen: EXP group will receive 3-day training of 101 lung sounds. Statistical Methodology: Results will be analyzed with the SPSS (version 27) and Jamovi (version 2.3.21). A p-value < 0.05 will be considered statistically significant. The effect of 3 levels of white noise on the EXP group will be compared utilizing a one-way analysis of variance (ANOVA) statistical test. Though, if data does not adhere to a normal distribution then Kruskal - Wallis will be applied. McNemar's test will be used to compare if there was a statistical difference between second-year and third-year students.

Primary | Students' Accuracy, Specificity, and Sensitivity Measurements under Different White Noise | Measures of medical students' specificity, sensitivity and accuracy in identifying pathological lung sounds will be assessed under 3 levels of white noise (WN). The WN is created by using a sinus wave. The sinus wave is added to the 15s lung sound recordings. The signal-to-noise ratio (SNR) levels are SNR-20; SNR-40 and no WN. The SNR-20 is perceived as the loudest WN by a human subject. Once each of the 9 questions (each containing six 15s lung sound recordings) is created the files are uploaded to the SAITI website. The result is 9 cases with no SNR; 9 cases with SNR-40; 9 cases with SNR-20. During the examination, a student is asked to listen to each of the six points for each case and then decide if pathology is present. The test results are tabulated for true positives (TP), true negatives (TN), false positives (FP), and false negatives (FN). The diagnostic values are compared at different levels of WN (SNR-20; SNR-40; no-SNR). | Approximately 4 weeks from the start until the last subject finish the study. |
