Methods In the case-control study, 20 adults and 20 children with normal hearing were evaluated for the loudness growth functions using the modified Contour test and then retested 10 children selected randomly a week later after the initial test.
方法：对听力正常的20例成人、20例儿童采用临床对照试验用改良的Contour试验进行响度测试，并在初测一周后对10名随机选择的儿童受试者进行复测。
Besides, in this article, a new weighting filter is worked out according to the new ISO equal loudness contour.
另外，本文还根据ISO226：2003的等响曲线标准，设计出了一个新的等响加权滤波器。
Due to checking figure in Stevens model algorithm, it is not easy to programming. According to the Stevens Equal Loudness Contour, figure formula was studied and improved the Stevens chart method, then obtained with MATLAB programming platform.
由于Stevens响度模型算法主要是查图法，不易于编程实现，本文根据Stevens等响度曲线图求得查图公式，改进了Stevens查图方式，并用MATLAB平台编程实现。
