摘要
本文分析了我国科技型企业孵化器标准化现状,阐述了当前科技企业孵化器标准化存在的问题,并提出了孵化器标准化的对策和建议,有助于推动孵化器标准体系的建设和发展.
The bad experience originated from the radiated noise of range hoods has attracted considerable attention in the market. The present criteria for noise evaluation cannot accurately reflect the users’ auditory perception. In this study, subjective assessment experiment of the range hood is designed and accomplished from the perspective of sound quality. The sound quality index model is constructed by using multiple linear regression with three psychoacoustic parameters, and the accuracy and generalization of the model are verified. This study has laid a foundation for the study of sound quality of products, provided a basis for the establishment of noise evaluation standards for range hoods, helped for assessing and testing sound quality for domestic appliances and filled in the gaps in the industry.
