Abstract
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.
