对于助听器的表征，新的国际电工委员会标准60118-15中定义了一种新的测试方法。对于这一特征，助听器将被设置为由助听器制造商的标准配件软件编程的实际用户设置。为了限制编程结果的变化，已经定义了10个标准听力图，它们覆盖了临床实践中遇到的所有听力图范围。这篇文章描述了一套标准听力图是如何开发出来的。这套标准听力图是通过矢量量化分析方法在28,244张听力图数据库上得出的。用这种分析方法，得到了12号和60号的几组典型的听力图。事实证明，由于没有倾斜的听力图，较小的一套不能用于选择听力图。因此，对较大的集合进行了分析，为平坦和中度倾斜的听力损失提供了七个标准听力图，为重度听力损失提供了三个标准听力图。
For the characterization of hearing aids, a new test method has been defined in the new International Electrotechnical Commission (IEC) standard 60118-15. For this characterization, the hearing aid will be set to actual user settings as programmed by standard fitting software from the hearing aid manufacturer. To limit the variation of programming outcomes, 10 standard audiograms, which cover the entire range of audiograms met in clinical practice, have been defined. This article describes how the set of standard audiograms has been developed. This set of standard audiogram has been derived by a vector quantization analysis method on a database of 28,244 audiograms. Using this analysis method, sets of typical audiograms have been obtained of sizes 12 and 60. It turned out that the smaller set could not be used for selecting audiograms as sloping audiograms were absent. Therefore, the larger set has been analyzed to provide seven standard audiograms for flat and moderately sloping hearing loss and three standard audiograms for steep hearing loss.
