Abstract: As a study on the effect of sound on the human body we conducted an acoustic psychological analysis on the sound of dadeumi. It is a research that puts a well-folded fabric on a stone and puts a cloth on the bat and spreads the wrinkles. The sound is bright and clear and makes you feel better. The reason why the pleasant sound is caused by what reason is examined through the material of the tool and how to use it. In addition, the sound components were analyzed by acoustic analysis and acoustic psychological analysis was performed using EEG analysis and Morse test. The tool is a set of plastered stones and two batts. The plastered stones are made of marble and the bats are made of birch. Scratchy looks like a banging action that creates a jolly rhythm and the intensity is controlled to play a musical instrument. Acoustically, the low frequency of less than 1,000 Hz and the sound of 3, 000~4, 000 Hz band are harmoniously suitable for the psychological response of the person. EEG analysis showed that EEG spectrographs with higher intracranial pressure frequencies were formed in the order of exoskeleton and twinning rather than rhythm. In the Morse test, the more the rhythm and harmony were produced by the rhythm than the simple rhythm sound, the higher the psychological response was. Sounds generated by traditional Korean tools as well as musical instruments must be studied in the future.
