IEC 60318-7:20 22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的靠近耳朵的声源。 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。 IEC 60318-7:20 22取消并取代IEC TS 60318-7:20 17。本版构成技术修订版。 本版本包括以下与IEC TS 60318-7:20 17相关的重大技术变更: a)更改标题； b)将范围扩展到靠近耳朵的声源。

IEC 60318-7:2022 describes a head and torso simulator, or manikin, intended for the measurement of sound sources placed close to the ear 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.
IEC 60318-7:2022 cancels and replaces IEC TS 60318-7:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC TS 60318-7:2017:
a) changing the title;
b) extending the scope to sound sources close to the ear.
