Clause Requirement + Test Result - Remark Verdict


TR F No. IEC62368_1 C
Alternatively, the instructional safeguard may be
given throug h the equipment display during use.

The elements of the instructional safeguard shall
be as follows:
– element 1a: the symbol , IEC 60417 - 6044
(2011 - 01)
– element 2: “High sound pressure” or equivalent
wording
– element 3: “Hearing damage risk” or equiva lent
wording
– element 4: “Do not listen at high volume levels for
long periods.” or equivalent wording

An equipment safeguard shall prevent exposure of
an ordinary person to an RS2 source without
intentional physical action from the ordinary person
and s hall automatically return to an output level not
exceeding what is specified for an RS1 source when
the power is switched off.

The equipment shall provide a means to actively
inform the user of the increased sound level when
the equipment is operated with an output exceeding
RS1. Any means used shall be acknowledged by the
user before activating a mode of operation which
allows for an output exceeding RS1. The
acknowledgement does not need to be repeated
more than once every 20 h of cumulative listening
ti me.

NOTE 2 Examples of means include visual or audible signals.
Action from the user is always needed.

NOTE 3 The 20 h listening time is the accumulative listening time,
independent of how often and how long the personal music player
has been switched of f.

A skilled person shall not be unintentionally
exposed to RS3.

10.6.5.1 General requirements

Personal music players shall give the warnings as
provided below when tested according to EN 50332 -
3, usi ng the limits from this clause.

The manufacturer may offer optional settings to
allow the users to modify when and how they wish to
receive the notifications and warnings to promote a
better user experience without defeating the
safeguards. This allows th e users to be informed in
a method that best meets their physical capabilities
and device usage needs. If such optional settings N/A

are offered, an administrator (for example, parental
restrictions, business/educational administrators,
etc.) shall be able to lock any optional settings into a
specific configuration.

The personal music player shall be supplied with
easy to understand explanation to the user of the
dose management system, the risks involved, and
how to use the system safely. The user shall be
ma de aware that other sources may significantly
contribute to their sound exposure, for example
work, transportation, concerts, clubs, cinema, car
races, etc.
10.6.5.2 Dose - based warning and requirements

When a dose of 100 % CSD is reached, and at lea st
at every 100 % further increase of CSD , the device
shall warn the user and require an
acknowledgement. In case the user does not
acknowledge, the output level shall automatically
decrease to compliance with class RS1.

The warning shall at least clearly indicate that
listening above 100 % CSD leads to the risk of
hearing damage or loss. N/A
10.6.5.3 Exposure - based requirements

With only dose - based requirements, cause and
effect could be far separated in time, defying the
purpose of educating users abo ut safe listening
practice. In addition to dose - based requirements, a
PMP shall therefore also put a limit to the short - term
sound level a user can listen at.

The exposure - based limiter (EL) shall automatically
reduce the sound level not to exceed 100 dB (A) or
150 mV integrated over the past 180 s, based on
methodology defined in EN 50332 - 3.
The EL settling time (time from starting level
reduction to reaching target output) shall be 10 s or
faster.

Test of EL functionality is conducted according to
EN 50 332 - 3, using the limits from this clause. For
equipment provided as a package (player with its
listening device), the level integrated over 180 s
shall be 100 dB or lower. For equipment provided
with a standardized connector, the unweighted level
integrate d over 180 s shall be no more than 150 mV
for an analogue interface and no more than - 10
dBFS for a digital interface.

NOTE In case the source is known not to be music (or test
signal), the EL may be disabled. N/A
