1 Modification to Clause 3 .

3.3.19 Sound exposure
Replace 3.3.19 of IEC 62368 - 1 with the following definitions: N/A
3.3.19.1
momentary exposure level, MEL
metric for estimating 1 s sound exposure level from
the HD 483 - 1 S2 test signal applied to both channels,
based on EN 50332 - 1: 2013, 4.2.

Note 1 to entry: MEL is measured as A - weighted levels in dB.
Note 2 to entry: See B.3 of EN 50332 - 3:2017 for additional
information. N/A

TR F No. IEC62368_1 C
3.3.19.3
sound exposure, E

A - weighted sound pressure ( p ) squared and
integrated over a stated period of time, T

Note 1 to entry: The SI unit is Pa 2
s.
N/A
3.3.19.4
sound exposure level, SEL

logarithmic measure of sound exposure relative to a
reference value, E 0 , typically the 1 kHz
threshold of hearing in humans.

Note 1 to entry: SEL is measured as A - weighted levels in dB.

dB

Note 2 to entry: See B.4 of EN 50332 - 3:2017 for additional
information. N/A
3.3.19.5
digital signal level relative to full scale, dBFS

levels reported in dBFS are always r.m.s. Full scale
level, 0 dBFS, is the level of a dc - free 997 -
Hz sine wave whose undithered positive peak value
is positive digital full scale, leaving the code
corresponding to negative digital full scale unused

Note 1 to entry: It is invalid to use dBFS for non - r.m.s. levels.
Because the definition of full scale is based on a sine wave, the
level of signals with a crest factor lower than that of a sine wave
may exceed 0 dBFS. In particular, square wave signals may
reach +3,01 dBFS. N/A
2 Modification to Clause 10
N/A
10.6 Safeguards against acoustic energy sources
Replace 10.6 of IEC 62368 - 1 with the following: N/A
10.6.1.1 Introduction

Safeguard requirements for protection against long -
term exposure to excessive sound pressure
levels from personal music players closely coupled
to the ear are speci fied below. Requirements
for earphones and headphones intended for use
with personal music players are also covered.
A personal music player is a portable equipment
intended for use by an ordinary person , that:

– is designed to allow the user to listen t o audio or
audiovisual content / material; and N/A

TR F No. IEC62368_1 C
– uses a listening device, such as headphones or
earphones that can be worn in or on or
around the ears; and
– has a player that can be body worn (of a size
suitable to be carried in a clothing pocket) and
i s intended for the user to walk around with while in
continuous use (for example, on a street,
in a subway, at an airport, etc.).

EXAMPLES Portable CD players, MP3 audio players, mobile
phones with MP3 type features, PDAs or similar equipment.

Personal m usic players shall comply with the
requirements of either 10.6.2 or 10.6.3.

NOTE 1 Protection against acoustic energy sources from telecom
applications is referenced to ITU - T P.360.

NOTE 2 It is the intention of the Committee to allow the
alternative met hods for now, but to only use the dose
measurement method as given in 10.6.5 in future. Therefore,
manufacturers are encouraged to implement 10.6.5 as soon as
possible.

Listening devices sold separately shall comply with
the requirements of 10.6.6.
These requirements are valid for music or video
mode only.
The requirements do not apply to:
– professional equipment;

NOTE 3 Professional equipment is equipment sold through
special sales channels. All products sold through
normal electronics stores are consid ered not to be professional
equipment.

– hearing aid equipment and other devices for
assistive listening;
– the following type of analogue personal music
players:
• long distance radio receiver (for example, a
multiband radio receiver or world band radio
receiver, an AM radio receiver), and
• cassette player/recorder;

NOTE 4 This exemption has been allowed because this
technology is falling out of use and it is expected that
within a few years it will no longer exist. This exemption will not
be extended t o other technologies.

– a player while connected to an external amplifier
that does not allow the user to walk around
while in use.

For equipment that is clearly designed or intended
primarily for use by children, the limits of the
relevant toy standards may apply.

The relevant requirements are given in
