摘要
目的为客观评价真无线耳机适配度,量化定性指标对真无线耳机设计影响,降低人在决策产品方案过程中的主观性偏差,建立真无线耳机适配度评价模型。方法采用了层次分析法与加权灰色关联分析法。通过层次分析法来确定影响真无线耳机适配度评价的影响权重值,建立了包括3项准则与12项指标的评价体系。进一步结合加权灰色关联分析法计算出4款真无线耳机备选方案与最优方案关联度,建立对各方案的优劣排序。结论建立了精准评价耳机适配度体验的评价体系,可评估得出符合耳机适配度需求的最佳耳机适配设计方案,其评估过程具有客观性和准确性。从检验结果可知,动态场景稳定度重要度权重较高,耳道空间及耳甲腔空间填充感次之,静态场景下的稳定度体验与耳朵分区压迫感体验权重最低,Apple AirPods Pro耳机与最优方案关联性最强。
To evaluate the fit of True Wireless Stereo(TWS)earphones objectively,quantify the influence of qualitative factors,and reduce the subjective bias on the decision-making of product design,the evaluation model of fit of TWS earphones was established.The analytic hierarchy process(AHP)and grey relational analysis(GRA)were used in this research.AHP was used for determining the weight value of the fit index of TWS earphones,including three value criteria and twelve indexes.In addition,GRA was utilized for calculating the correlation between four alternative products and optimal products and ranking all four products.Based on AHP and GRA methods,evaluation indexes on the fit of TWS earphones were established.The optimal earphone which meets the requirements of the fit requirement of TWS earphone was selected objectively and accurately.Consequently,the sense of stability of dynamic scene accounts for the highest proportion among all factors,following by the sense of volume of external auditory canal interspace and concha interspace.The proportions of sense of stability of static scene and sense of pressure of external ear regions are lower than others.In addition,the correlation between Apple AirPods Pro and the optimal solution is strongest.
