Sound system equipment: Headphones and earphones associated with personal music players - Maximum sound pressure level measurement methodology - Part 2: Matching of sets with headphones if either or both are offered separately, or are offered as one package equipment but with standardised connectors between the two allowing to combine components of different manufacturers or different design
This Part 2 of EN 50332 specifies methods of measuring the matching values for the use of personal music players and headphones/earphones defined for the use with those and with standardised connectors or interfaces allowing to combine components of different manufacturers or different design sold separately in order to avoid possible hearing impairment by excessive sound pressure resulting from them. Compared with “one-package sets“ the sound pressure level at the ear cannot be fixed by only one condition but needs at least two characteristics, one each for player and the headphones/earphones, defined by the matching values for their connection. Requirements for protection against excessive sound pressure from personal music players are given in EN 60950-1:2006/A12:2011 and EN 60065:2002/A12:2011.

Foreword
This document (EN 50332-2:2013) has been prepared by CLC/TC 108X, "Safety of electronic
equipment within the fields of Audio/Video, Information Technology and Communication Technology".
The following dates are fixed:
• latest date by which this document has to be
(dop) 2014-09-23
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards
(dow) 2016-09-23
conflicting with this document have to
be withdrawn
This document supersedes EN 50332-2:2003.
EN 50332-2:2013 includes the following significant technical changes with respect to
EN 50332-2:2003:
- deletion of limits;
- addition of digital signals;
- adaptations to use the term "personal music players".
EN 50332, Sound system equipment: Headphones and earphones associated with personal music
players Maximum sound pressure level measurement methodology, is composed with the following
parts:
− Part 1: General method for "one package equipment";
− Part 2: Matching of sets with headphones if either or both are offered separately, or are offered as
one package equipment but with standardised connectors between the two allowing to combine
components of different manufacturers or different design.
The Part 1 of this standard describes conditions and procedures for combination of player units and
headphones sold as “one-package sets”. The sound pressure limitation (SPL) of these sets is lost
when players or headphones with standardised sockets and plugs are arbitrarily combined.
This Part 2 provides measurement methods for the matching values which guarantee the SPL limit
also for the aforementioned condition.

1 Scope
This Part 2 of EN 50332 specifies methods of measuring the matching values for the use of personal
music players and headphones/earphones defined for the use with those and with standardised
connectors or interfaces allowing to combine components of different manufacturers or different
design sold separately in order to avoid possible hearing impairment by excessive sound pressure
resulting from them.
Compared with “one-package sets“ the sound pressure level at the ear cannot be fixed by only one
condition but needs at least two characteristics, one each for player and the headphones/earphones,
defined by the matching values for their connection.
Requirements for protection against excessive sound pressure from personal music players are given
in EN 60950-1:2006/A12:2011 and EN 60065:2002/A12:2011.
