Verdict
All other equipment shall:
a) protect the user from unintentional acoustic outputs
exceeding those mentioned above; and
b) have a standard acoustic output level not exceeding those
mentioned above, and automatically return to an output level
not exceeding those mentioned above when the power is
switched off; and
c) provide a means to actively inform the user of the increased
sound pressure when the equipment is operated with an
acoustic output exceeding those mentioned above. Any
means used shall be acknowledged by the user before
activating a mode of operation which allows for an acoustic
output exceeding those mentioned above. The
acknowledgement does not need to be repeated more than
once every 20 h of cumulative listening time; and
NOTE 2 Examples of means include visual or audible signals.
Action from the user is always required.
NOTE 3 The 20 h listening time is the accumulative listening time,
independent how often and how long the personal music player
has been switched off.
d) have a warning as specified in Zx.3; and
e) not exceed the following:
1) equipment provided as a package (player with Its
listening device), the acoustic output shall be ≤ 100 dBA
measured while playing the fixed “programme simulation
noise” described in EN 50332-1; and
2) a personal music player provided with an analogue
electrical output socket for a listening device, the electrical
output shall be ≤ 150 mV measured as described in EN 50332-
2, while playing the fixed “programme simulation noise”
described in EN 50332-1.
For music where the average sound pressure (long term
LAeq,T) measured over the duration of the song is lower than
the average produced by the programme simulation noise, the
warning does not need to be given as long as the average
sound pressure of the song is below the basic limit of 85 dBA.
In this case T becomes the duration of the song.
NOTE 4 Classical music typically has an average sound pressure
(long term LAeq,T) which is much lower than the average
programme simulation noise. Therefore, if the player is capable to
analyse the song 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 is below the basic limit of 85
dBA.
For example, if the player is set with the programme simulation
noise to 85 dBA, but the average music level of the song is only
65 dBA, 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 dBA.
