Safeguard requirements for protection against long -

levels from personal music players closely coupled

for earphones and headphones intended for use

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

– 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.

10.6.1.2 Non - ionizing radiation from radio frequencies in
the range 0 to 300 GHz
The amount of non - ionizing radiat ion is regulated by
European Council Recommendation 1999/519/EC of
12 July 1999 on the limitation of exposure of the
general public to electromagnetic fields (0 Hz to 300
GHz).
For intentional radiators, ICNIRP guidelines should
be taken into account for L imiting Exposure to Time -
Varying Electric, Magnetic, and Electromagnetic
Fields (up to 300 GHz). For hand - held and body
mounted devices, attention is drawn to EN 50360
and EN 50566. N/A
10.6.2 Classification of devices without the capacity to estimate so und dose
N/A
10.6.2.1 General
This standard is transitioning from short - term based
(30 s) requirements to long - term based (40 hour)
requirements. These clauses remain in effect only
for devices that do not comply with sound dose
estimation as stipulated in EN 50332 - 3.
For classifying the acoustic output L Aeq , T ,
measurements are based on the A - weighted
equivalent sound pressure level over a 30 s period.
For music where the average sound pressure (long
term L Aeq , T ) measured over the duration of the song
is lower than the average produced by the
programme simulation noise, measurements may be
done over the duration of the complete song. In this
case, T becomes the duration of the song.
NOTE Classical music, acoustic music and broadcast typically
has an av erage sound pressure (long term L Aeq , T ) which is much
lower than the average programme simulation noise. Therefore, if
the player is capable to analyse the content and compare it with
the programme simulation noise, the warning does not need to be
given as long as the average sound pressure of the song does
not exceed the required limit.
For example, if the player is set with the programme simulation
noise to 85 dB, but the average music level of the song is only 65
dB, there is no need to give a warning or ask an
acknowledgement as long as the average sound level of the song
is not above the basic limit of 85 dB. N/A
