Abstract: An electronic device according to various embodiments comprises: a communication circuit configured to communicate with an external electronic device; a memory in which one or more sound sources and one or more test sounds for tinnitus frequency testing are stored; and at least one processor, comprising processing circuitry, wherein the memory can store instructions that when executed by at least one processor, individually and/or collectively, cause the electronic device to: transmit a first control message to the external electronic device so that the one or more test sounds are output through the external electronic device corresponding to an ear with tinnitus identified from among the left ear and the right ear on the basis of a first input; determine a tinnitus frequency corresponding to a test sound selected from among the one or more test sounds on the basis of a second input; and transmit a second control message to the external electronic device so that a second sound source obtained by removing a po

Abstract: A method of manufacturing a shoe insole includes an upper cover layer and a lower cover layer conforming in shape to the inner bottom of the shoe, and an insole body retained between the upper cover layer and the lower cover layer, taking a foot sole form to which pads are applied to selected regions of a sole taking a foot sole form; manufacturing an insole frame having a shape conforming to a three-dimensional shape of the foot sole form and applying insole pads to an upper surface of the insole frame, based on positions of marks of the test pads of the foot sole form to which the pads are applied, wherein the insole body includes the insole frame to which the insole pads are applied.

Abstract: A method of playing music based on chords in an electronic device is provided. The method includes identifying background music related to a piece of music to load sound source data synchronized with the background music from a memory, reproducing the background music, identifying chords corresponding to the reproduced background music in the sound source data, configuring notes corresponding to the chords as notes corresponding to touch objects displayed on the touch screen, and when the chords are changed, reconfiguring notes corresponding to the changed chords as the notes corresponding to the touch objects.
