44 FOREWORD
45 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
46 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
47 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
48 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
49 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
50 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
51 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
52 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
53 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
54 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
55 consensus of opinion on the relevant subjects since each technical committee has representation from all
56 interested IEC National Committees.
57 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
58 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
59 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
60 misinterpretation by any end user.
61 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
62 transparently to the maximum extent possible in their national and regional publications. Any divergence between
63 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
64 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
65 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
66 services carried out by independent certification bodies.
67 6) All users should ensure that they have the latest edition of this publication.
68 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
69 members of its technical committees and IEC National Committees for any personal injury, property damage or
70 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
71 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
72 Publications.
73 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
74 indispensable for the correct application of this publication.
75 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
76 rights. IEC shall not be held responsible for identifying any or all such patent rights.
77 IEC 63296-2 has been prepared by technical area 19: Environmental and energy aspects for
78 multimedia systems and equipment, of IEC technical committee 100: Audio, video and
79 multimedia systems and equipment. It is an International Standard.
80 The text of this International Standard is based on the following documents:
FDIS Report on voting

100 INTRODUCTION
101 This document specifies a measurement method for battery duration on active acoustic noise
102 cancelling headphones and earphones. Active acoustic noise cancelling headphones and
103 earphones are commonly used to reduce the environmental acoustic noise to which the ear is
104 exposed. However, there is no international standard for a battery duration measurement
105 method of active acoustic noise cancelling headphones and earphones. Each company
106 evaluated the performance using its own method, and the evaluation values were not uniform.
107 This standard for the measurement of the battery duration and the notation of measured value
108 allows the comparison of performance data obtained in different locations.
109 IEC 63296 series currently consists of the following planned or published parts:
110 – Part 1: Powered loudspeaker equipment
111 – Part 2: Headphones and earphones with active noise-cancelling functions

117 Part 2: Headphones and earphones with
118 active noise cancelling functions
122 1 Scope
123 This document is applicable to active acoustic noise cancelling headphones and earphones
124 which have the function of reducing the noise heard by the user by the output sound from the
125 transducer generated by the environment noise detection microphone and the noise reduction
126 signal processing circuit.
127 This document specifies the terms and definitions relating battery duration of this type of
128 headphones or earphones and the measurement and evaluation methods.
129 This document covers headphones and earphones to be worn over-the-ear or in-ear, all of which
130 are referred to as headphones in this document.
131 The noise detection microphones are mounted in the body, on the surface, or on an accessory
132 of the headphones or earphones. Signal processing circuits are analogue and digital electronic
133 circuits.
134 This document does not deal with equipment intended for hearing protection. It is also not
135 applicable to music players, recorders, etc. that have a noise cancelling function.
136 The battery duration measurement methods may be applied to headphones and earphones
137 having no active noise cancelling function.
