Sound system equipment - Part 7: Headphones and earphones IEC 60268-7/FRAGF ED3

Scope

IEC 60268-7:2010 is applicable to headphones, headsets, earphones and earsets, intended to be used on, or in, the human ear. It also applies to equipment, such as pre-amplifiers, passive networks and power supplies which form an integral part of the headphone system.
It does not deal with:
a) safety, for which reference should be made to IEC 60065 or another appropriate standard;
b) the characteristics of microphones of headsets, for which reference should be made to IEC 60268-4;
c) earphones and other devices for hearing aids, for which reference should be made to IEC 60118-0;
d) headphones for audiometry;
e) headphones and other devices which form part of an active ear-defender system, although some of its provisions may be applicable.
It specifies the characteristics which should be included by the manufacturer in specifications, and relevant methods of measurement. It includes a classification of the different types of earphone, mainly characterized by the way in which the transducer is coupled acoustically to the ear, and a classification code which may also be used for marking.
IEC 60268-7:2010 cancels and replaces the second edition published in 1996, and constitutes a technical revision. This edition contains the following changes:
- clause/subclause renumbering in accordance with ISO/IEC Directives, Part 2;
- addition of a measurement system using HATS;
- addition of details on pinna simulators for high measurement reproducibility, see Annex A. The contents of the corrigendum of November 2012 have been included in this copy.
