Abstract: Proposed are a method and device of determining optimal complex stimuli for tinnitus treatment. The method of determining the optimal complex stimuli for tinnitus treatment includes: identifying one or more sound stimuli selected by a user input from among a plurality of sound stimuli; identifying one or more electrical stimuli selected by the user input from among a plurality of electrical stimuli; determining a first complex stimulus sequence of complex stimuli in which the one or more selected sound stimuli and the one or more selected electrical stimuli are combined; and applying the complex stimuli to a user, wearing a tinnitus treatment device, according to the determined first complex stimulus sequence.

Abstract: A diagnostic method and a classification method for patients with tinnitus, and a method for providing personalized treatment protocols for the patients with the tinnitus are proposed.

Abstract: The present invention relates to a vagus nerve stimulation device for animals, the device comprising an electrode that contacts the animal's skin to transmit electrical stimuli and a power source for generating electrical stimuli transmitted to the electrode. The present invention has an excellent effect of stabilizing the psychological state of an animal by stimulating the vagus nerve from the outside of the animal. For companion animals, the present invention has the effect of eliminating aggression, relieving and stress, reducing separation anxiety. In the case of livestock animals, there are the effects of improving meat quality and increasing milk production by reducing breeding stress even without the aid of drugs or the like. For leisure animals or sports animals, the excellent effects of imparting psychological stability to reduce the risk of accidents due to psychological stability, improving recovery from fatigue, and improving exercise ability can be brought about.

Abstract: The present invention relates to a method for controlling a complex stimulation, which is a method for controlling a complex stimulation device having an electrical stimulation unit including electrodes in contact with human ears and a sound output unit for stimulating hearing by using sound waves, wherein the sound output unit generates sound waves having different frequencies in both ears, and controls the frequency difference between the sound waves applied to both ears on the basis of frequencies of electrical stimulation applied to the electrodes. The present invention has an excellent effect of improving the efficiency of electrical stimulation to the vagus nerve by stimulating the brain with two types of stimulation by adding acoustic stimulation together when stimulating the vagus nerve through the electrodes in contact with the ears.

Abstract: Proposed is a vagus nerve stimulator having at least two electrodes that are configured to be worn on at least one of the left and right ears and are configured to generate electrical stimulation on the vagus nerve in the auricle. The vagus nerve stimulator may include: a body part configured to be located on a side of a wearer's ear; a first electrode configured to be inserted into and make contact with the external acoustic meatus of the wearer's ear; a second electrode configured to make contact with the cymba concha of the wearer's ear; a first electrode fixing part protruding from the body part and having a first electrode at an end thereof; and a second electrode fixing part protruding from the body part and having a second electrode at an end thereof.
