Abstract: The present invention relates to a head mounted display (HMD) for adaptively augmenting virtual audio signals according to an actual audio signal-listening environment, and to a method for providing audio content by using same. To this end, the present invention provides the HMD comprising: a processor for controlling the operation of the HMD; a microphone unit for receiving real sound; and an audio output unit for outputting a sound based on a command from the processor, wherein the processor receives the real sound using the microphone unit, obtains a virtual audio signal, extracts spatial audio parameters by using the received real sound; filters the virtual audio signal using the extracted spatial audio parameters, and outputs the filtered virtual audio signal to the audio output unit.
