In order to overcome the adaptability of electrical stimulation produced by the traditional electro acu-puncture and improve the effects of electro acupuncture, a new type of music electro acupuncture instrument has been designed based on ARM. This article put forward to choose the music as prescription whose spectral density met the 1/f fluctuation law in order to make the patients more comfortable accepting electrical stimulation. What’s more, the music prescription for insomnia had been designed. At last, a total of 23 insomniacs were randomly divid-ed into three groups to verify the therapeutic effects. Clinical tests showed that the scheme in this paper was feasible and the treatment effect was significant.
