| Abstract(J) | インバータ音はキャリア周波数およびその側帯波による複数の純音成分で構成される．近年ではキャリア周波数を変調させることで純音成分を分散し，マスキング効果の向上を図る制御が用いられている．本研究では変調幅などの制御パラメータが不快度に与える影響を定量的に評価し，不快度低減に有効な変調条件を明らかにした． Translation |
| Abstract(E) | Inverter noise consists of multiple pure-tone components generated by the carrier frequency and its sidebands. In recent years, carrier frequency modulation has been used to spread these pure-tone components and improve masking effects. In this study, the effects of modulation parameters, such as modulation width, on unpleasantness were quantitatively evaluated, and effective modulation conditions for reducing unpleasantness were clarified. |
