In recent years, the music market has changed from CD to digital distribution. MP3 is the representative compressed sound source of online music distribution services. However, MP3 formatted quality is inferior to uncompressed sound sources such as CD-DA formatted. Because MP3 formatted quality has less information as compared to pre-compressed data and MP3 sound source is changed data on the basics of audio property. The object of study is by analyzing EEG to determine if people can recognize such difference sound. This time we divide into two subject patterns which worry about less information quality data such as MP3 formatted whereas others don't worry about less information data. And we compered uncompressed sound and compressed sound while LPCM(CD-DA,16bit/44.1Hz) sound source and MP3 (64kbps,128kbps,256kbps,320kbps) sound sources by use of EEG analysis. As a result we cloud find the difference. So we report the progress of this study.
