クラシックギター音質へのエイジング効果

抄録

We report the result of test that has given the acoustic excitation to the new guitar in the aging cell with using the Bach's cello suites. The sound quality effect of playing the guitar for five years is the same as one of the four weeks aging test with the high load. However, the too much aging gives the new guitar the adverse effects. In this time, we were able to have the good balance results with the light load aging. But there were few effects in the upper position sounds of the guitar. The sound range of the cello is not enough to the acoustic excitation of high frequency zone. So, we will try soon the aging test with playing the violin pieces.
