It also specifies requirements for earphones and headphones intended for use with personal music players.A personal music player is a portable equis designed to allow the user to listen to recorded or broadca

13、st sound or video; andprimarily uses headphones or earphones that can be worn in or on or around the ears; andallows the user to walk around while in use.NOTE 1 Examples are hand-held or body-worn portable CD players, MP3 audio players, mobile phones with MP3 typefeatures, PDA s or similar equipment

14、.A personal music player and earphones or headphones intended to be used with personal music players shall comply with the requirements of this sub-clause.The requirements in this sub-clause are valid for music or video mode only.The requirements do not apply:while the personal music player is conne

15、cted to an external amplifier; orwhile the headphones or earphones are not used.NOTE 2 An external amplifier is an amplifier which is not part of the personal music player or the listening device, but which isintended to play the music as a standalone music player.The requirements do not apply to:he

This exemption will not be extended to other techn

18、ologies.For equipment which is clearly designed or intended for use by young children, the limits of EN 71-1 apply.Zx.2 Equipment requirementsNo safety provision is required for equipment that complies with the following:equipment provided as a package (personal music player with its listening devic

19、e), where the acoustic output L Aeq,T is 85 dBA measured while playing the fixe d “ programme simulation noise ” as described in EN 50332 -1; and a personal music player provided with an analogue electrical output socket for a listening device, where the electrical output is 27measured as described

20、in EN 50332-2, while playin g the fixed“ programme simulation noiseas described in EN 50332-1.NOTE 1 Wherever the term acoustic output is used in this clause, the 30 s A-weighted equivalent sound pressure level Lis meant. See also Zx.5 and Annex Zx.All other equipment shall:a) protect the user from

21、unintentional acoustic outputs exceeding those mentioned above; andb) 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; andmVc) provide a means to actively inform

22、the user of the increased sound pressure when the equipment is operated with an acoustic output exceedingthose mentioned above. Any meansused shall be acknowledged by the user before activating a mode of operation which allows for an acoustic output exceeding those mentioned above. Theacknowledgemen

25、-1; and2) a personal music player provided with an analogue electrical output socket for a listening device, the electrical output shall be 1 measured as described in EN 50332-2, while playing the fixed“ programme simulation noisedescribed in EN 50332-1.For music where the average sound pressure (lo

26、ng term L Aeq,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.N

27、OTE 4 Classical music typically has an average sound pressure (long term L) 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 th

28、e 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 l

29、evel of the song is not above the basic limit of 85 dBA.d50 mVZx.3 WarningThe warning shall be placed on the equipment, or on the packaging, or in the instruction manual and shall consist of the following:the symbol of Figure 1 with a minimum height of 5 mm; andthe following wording, or similar:“ To

30、 prevent possible hearing damage, do not listen at high volume levels for long periods.Figure 1 Warning label (IEC 60417-6044) Alternatively, the entire warning may be given through the equipment display during use, when the user is asked to acknowledge activation of the higher level.Zx.4 Requiremen
