Abstract
An embodiment of the present disclosure provides an audio signal processing device configured to transmit/receive an audio signal to/from an external acoustic output device that includes a microphone and an acoustic output means, including a transmission/reception module configured to transmit/receive a signal to/from the external acoustic output device, and a processor configured to control an operation of the transmission/reception module, wherein the processor transmits an audio output signal to the external acoustic output device through the transmission/reception module, receives, through the transmission/reception module, an input signal to which an external acoustic collected through the microphone is converted while the acoustic output means outputs an acoustic based on the audio output signal, and compares the audio output signal with the input signal to determine whether a user wears the acoustic output means of the external acoustic output device.
