Abstract: In this study, we have studied how to improve symptoms by using sound for delayed urination, one of theurination disorders. Research has been carried out to prove that the urine flow is in line with the flow of water and that the urine flow improves urination by drawing the synchronized phenomenon. As a research method, we studied the contents related to urination as a symptom study and the study of sound for promoting of urination as a solution. Regarding the contents related to urination, we investigated the process of urination, the cause of delayed urination and abnormal urination. In order to investigate the sound for promoting of urination, waves, rivers, waterfalls, valleys, streams, tap water were also prepared to analyze the sound of water, and the brain waves and MOS test of the listener were also conducted. As a result, it was found that the acoustic characteristics of water sound and the sound characteristics of sound produced during urination are common. In addition, through the MOS (Mean Opinion Score) test of the listeners, it was found that the water sounds most similar to the urine generated during vigorous urine drainage helped urination and other water sounds also had a positive effect.
