Electronic device for listening to external sound and operating method of electronic device

Abstract

The present disclosure relates to an electronic device and an operating method thereof, the electronic device comprising: a speaker; an external microphone configured to obtain an external signal for the electronic device; an internal microphone positioned within a specified distance of the speaker and configured to obtain an internal signal including a signal output from the speaker and/or a signal obtained from the signal output from the speaker and reflected by an external object; a memory storing a first transfer function generated on the basis of the signal output from the speaker and obtained by the internal microphone, and/or a second transfer function generated on the basis of the signal obtained from the signal output from the speaker and reflected by the external object, the signal being obtained by the internal microphone; and a processor operatively connected to the speaker, the external microphone, and the internal microphone, wherein the processor may be configured to: convert a signal obtained by the external microphone into an external frequency signal in the frequency domain; convert a signal obtained by the internal microphone into an internal frequency signal in the frequency domain; calculate a first compensation value on the basis of comparing the external frequency signal with the internal frequency signal; and control an output signal output from the speaker, on the basis of the external signal obtained by the external microphone, the first compensation value, and the first transfer function and/or the second transfer function.
