The present invention measures personal hearing status through an open wireless or wired ear-level device individually made of soft silicone material using 3D scanning and printing technology and an acoustic device interlocked by a smartphone application for driving the ear-level device. In addition, it provides the optimal volume for the individual hearing state through the acoustic correction for each frequency of the therapeutic stimulation sound, and provides a variety of treatment stimulation sounds and brain wave control treatment sounds capable of selectively stimulating the cerebral auditory region and periodic treatment Tinnitus self-treatment system according to the individual hearing state that provides an algorithm for selecting a treatment program through sexual evaluation, which is worn on a user's left ear and right ear and can be provided by wireless or wired connection to each other, customized to the user's ear Built-in acoustic element housing and a speaker 110 for outputting sound transmitted through wired or wirelessly to the acoustic element housing, an ear level device 100 for outputting a treatment sound whose output is corrected for each frequency according to an individual hearing condition ), and transmits a diagnostic sound, a treatment sound, or an EEG-controlled treatment sound to the speaker 110 of the ear level device 100, and outputs sound source data optimized for a user's hearing state by being corrected for each frequency by a certain dBHL interval. A sound source output unit 220; When measuring hearing and tinnitus, a sound source whose intensity and/or frequency has been changed is called and output according to whether a user's test tone and a user's response signal are received from the sound source output unit 220 through a user's hearing test. A first control unit 210 that stores the response signal reception information of and performs equalization of the treatment volume of the user for each of a plurality of frequency ban
