| Abstract(in English) | A lot of excellent performances with high historical value and scarcity value exist in the SP record, and there is the one made CD as a reprint version now, too. However, the SP record is a current state that the ditch is superimposed from loss to the reproduction sound by a very jarring noise, doesn't suppress the noise of the problem on the material by the state of preservation for the one with a cruel noise, and made CD as it is. In this thesis, the noise of the SP record reproduction sound was suppressed by using general harmony analysis (GHA) that a high effect of the noise suppression expected and is bright. However, Musical Noise is generated in the signal after the noise is suppressed. Then, authors succeeded in more advanced noise suppression while suppressing the generation of Musical Noise by clarifying the cause of the Musical Noise generation, and proposing "Multistep GHA" as a new improvement idea. |
