摘要
本文基于多款IH电饭煲声品质较差问题,通过采集其噪声样本数据,并进行分析计算,得到该IH饭煲A计权声压级、响度、尖锐度等声品质客观评价参量值;同时运用评分法的规则收集该多款IH饭煲的主观评价结果;最终结合主、客观评价结果的线性回归分析,提出一套科学的IH饭煲噪声声品质客观评价方法,优化了传统的声品质评价方式。
Based on the poor sound quality of many IH rice cookers,this paper collects noise sample data and analyzes and calculates to obtain objective evaluation parameters of sound quality such as A-weighted sound pressure level,loudness,and sharpness of the IH rice cooker;The rules of the scoring method collect the subjective evaluation results of the various IH rice cookers;finally,combined with the linear regression analysis of the subjective and objective evaluation results,a set of scientific objective evaluation methods for the noise and sound quality of the IH rice cookers are proposed,which optimizes the traditional sound quality evaluation the way.
