Claim Text:
1. A method of controlling a sound outputting apparatus, the method comprising: receiving a sound; extracting, from the sound, a noise signal and a desired signal in a frequency domain, wherein the noise signal is extracted based on static characteristics of the sound, and the desired signal is extracted based on dynamic characteristics of the sound; estimating a direction of arrival (DoA) of the extracted desired signal, with respect to a user of the sound outputting apparatus; adjusting a DoA of the extracted noise signal based on the estimated DoA of the extracted desired signal to spatially separate the noise signal and the desired signal; and outputting an adjusted sound according to a result of the adjusting, wherein the adjusting of the DoA of the extracted noise signal comprises adjusting the DoA of the extracted noise signal to be substantially opposite to the DoA of the desired signal.
