Currently, many types of non-reversible compressed sound source, represented by MP3 (MPGE Audio Layer^), are widely used to make the voice file size smaller. Here, the non-reversible compression means the data compression method the data compressed and deployed by which is not completely coincided with the data before compression. The sound data created in this way has less information as compared to pre-compressed data. The object of this study is by analyzing brain waves to determine if people can recognize such differences as differences in sound.
