This European Standard was approved by CENELEC on 2003-07-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 206, Consumer
equipment for entertainment and information and related sub-systems.
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 matching values which guarantee the SPL limit also for the aforementioned condition.
This text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC
as EN 50332-2 on 2003-07-01.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-07-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2006-07-01

1 Scope
This Part 2 of EN 50332 specifies matching values for the use of battery-operated audio equipment and
headphones/earphones defined for the use with those and with standardised connectors 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.
