Clinical effectiveness of sedative music on sleep quality was investigated. Subjects were 14 females aged 40s to 70s, and methods included listening to music during going to sleep using by sound sleep support sound player “Lullaby reverberation (Komoriuta-no-Hibiki)”, which was evaluated by Pittsburgh Sleep Quality Index (PSQI) in 0,4,8 weeks. Thirteen cases showed decreased points of PQSI. Time to sleep and sleep duration were almost the same. The relationship figure for PSQI and time until sleeping showed general tendency of left and horizontal/lower directional arrows. These results suggest positive beneficial effect of music for sleep quality evaluated by PSQI.
