IEC 60268-7:2010(E), 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 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. 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.
