IEC TS 60318-7:20 17（E）描述了一种头部和躯干模拟器或人体模型，旨在测量频率范围为100 Hz至16 000 Hz的空气传导助听器。 本文件中描述的人体模型仅用于机载声学测量。它不适用于依赖于振动传输路径（如骨传导）的测量，或需要模拟骨或组织的测量。 本文件规定了人体模型的几何尺寸和声学特性。只有符合两套规范的人体模型才符合本文件。 与上一版相比，此版本包括以下重大技术变更: a)该文档基于三种不同常用类型的人体模型的设计；b)先前版本的头部、躯干和耳廓模拟器的横截面被其几何尺寸的最大值和最小值所取代； c)添加人体模型的扩散场频率响应； d)可用频率范围扩展至100Hz至16000Hz； e)除了圆柱形耳道延伸部之外，增加锥形耳道延伸部； f)附件中给出了一个解剖学形状的人体模型和两个不同几何形状的人体模型的设计实例； g)公差区间、相应的验收区间和最大允许测量不确定度之间的关系在附件中给出； h)附录中给出了三种不同类型耳廓模拟器的3D表示。

IEC TS 60318-7:2017(E) describes a head and torso simulator, or manikin, intended for the measurement of air-conduction hearing aids in the frequency range from 100 Hz to 16 000 Hz.
The manikin described in this document is intended for airborne acoustic measurements only. It is not suitable for measurements which depend upon vibration transmission paths such as bone conduction, or for measurements requiring the simulation of bone or tissue. 
This document specifies the manikin in terms of both its geometrical dimensions and its acoustical properties. Only manikins compliant with both sets of specifications are in conformance with this document.
This edition includes the following significant technical changes with respect to the previous edition:
a)   the document is based on the designs of three different commonly used types of manikins;
b)   the cross sections of the head and torso and pinna simulators of the previous edition are replaced by maximum and minimum values of their geometric dimensions;
c)   the diffuse field frequency response of the manikin is added;
d)   the usable frequency range is extended to 100 Hz to 16 000 Hz;
e)   in addition to the cylindrical ear canal extension a tapered ear canal extension is added;
f)   design examples of one anatomically shaped manikin and of two different geometrically shaped manikins are given in the annexes;
g)   the relationship between tolerance interval, corresponding acceptance interval and the maximum permitted uncertainty of measurement are given in an annex;
h)   3D representations of three different types of pinna simulators are given in an annex.
