声品质技术探讨

Discussion of sound quality

伴随着中国的制造业发展,人们越发重视产品噪声对听众心理、生理的影响。从声品质遵照的心理声学理论基础、声品质常用的数据采集分析方法、声品质分析技术的实际应用及现阶段声品质技术的局限和相应的未来工作计划四个方面对声品质技术进行了探讨。

During the development of industries, subjective evaluation and sound quality evaluation system are building grea- ter and greater values in the product design and attracting increasing interest of the academic. A series of four sections will introduce the logical chain of evaluation system which creates the bridgebetween the objective acoustic performance and the sensory pleasantness or annoyance. Then the basic concepts based on the theoretic of psycho-acoustics ; the common data ac- quisition methods and results analysis;the application of sound quality teehnology. Finally the limitations of sound quality methodologies are pointed out and the future development is prospected.
