An electronic device comprises a speaker, a microphone, memory, a digital signal processor (DSP), a driver for converting a digital signal output from the digital signal processor into an analog signal and outputting same to the speaker, and a processor operatively connected to the speaker, microphone, memory, digital signal processor and driver. The processor: controls the digital signal processor and driver to output a first sound signal, in which a signal of a first frequency, a signal of a second frequency and a reverse phase signal of a third frequency associated with the distortion product otoacoustic emission (DPOAE) of the first frequency and second frequency are combined, by means of the speaker on the basis of a first protocol among a plurality of protocols stored in the memory; when a second sound signal associated with the first sound signal is received by means of the microphone, extracts a first distortion product otoacoustic emission signal of the third frequency included in the second sound signal; controls the digital signal processor and driver to output a third sound signal, in which a signal of a fourth frequency, a signal of a fifth frequency and a reverse phase signal of a sixth frequency associated with the distortion product otoacoustic emission (DPOAE) of the fourth frequency and fifth frequency are combined, by means of the speaker on the basis of a second protocol among the plurality of protocols; when a fourth sound signal associated with the third sound signal is received by means of the microphone, extracts a second distortion product otoacoustic emission signal of the sixth frequency included in the fourth sound signal; obtains a user hearing acuity profile on the basis of the first distortion product otoacoustic emission signal and second distortion product otoacoustic emission signal; and can change the volume and/or equalization (EQ) on the basis of the user hearing acuity profile.
