【摘要】 吸油烟机噪声给用户带来的不良体验已在市场上引起广泛重视。在吸油烟机行业内,噪声已成为设计人员最为关注的问题之一。对油烟机进行降噪的最终目的是提高吸油烟机声品质,使用户获得更好的声学体验。为达到这一目的,除单纯降低噪声声压级,更需深入考察噪声信号的时间结构、频谱结构等特性。本文通过主观实验对声品质进行评价,并通过多元回归分析建立吸油烟机声品质模型,为进一步基于声品质的噪声控制奠定基础。更多还原

【Abstract】 The noise radiated by range hoods has attracted wide attention in the market.Noise is also one of the most important issues for designers.The ultimate goal of noise reduction is to give end-users a better auditory perception and improve the sound quality.In addition to reduce noise pressure level,the spectral and temporal characteristics of noise are also investigated.In this study,the sound quality is evaluated by jury testing,and the sound quality model of hood is established by multiple regression analysis.The sound-qualitybased noise control approaches will be more appropriate for improving the commercial value of the range hoods.更多还原
