ZX rotection against excessive sound pressure from personal music players ZX.1 General 47 / 65

48 This sub-clause specifies requirements for protection against excessive sound pressure from personal music players that are closely coupled to the ear. It also specifies requirements for earphones and headphones intended for use with personal music players. A personal music player is a portable equipment for personal use, that: -is designed to allow the user to listen to recorded or broadcast sound or video; and -primarily uses headphones or earphones that can be worn in or on or around the ears; and -allows the user to walk around while in use. NOTE 1 Examples are hand-held or body-worn portable CD players, M3 audio players, mobile phones with M3 type features, DA s or similar equipment. 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 connected to an external amplifier; or -while the headphonesor 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 is intended to play the music as a standalone music player. The requirements do not apply to: -hearing aid equipment and professional equipment; NOTE 3 rofessional equipment is equipment sold through special sales channels. All products sold through normal electronics stores are considered not to be professional equipment. - analogue personal music players (personal music players without any kind of digital processing of the sound signal) that are brought to the market before the end of 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 to other technologies. For equipment which is clearly designed or intended for use by young children, the limits of EN 71-1 apply. ZX.2 Equipment requirements No safety provision is required for equipment that complies with the following: -equipment provided as a package (personal music player with its listening device), where the acoustic output LAeq,T is 85 dba measured while playing the fixed programmed simulation noise as described in EN a personal music player provided with an analogue electrical output socket for a listening device, where the electrical output is 27 mv measured as described in EN , while playing the fixed programmed simulation noise as described in EN NOTE 1 Wherever the term acoustic output is used in thisclause, the 30 s A-weighted equivalent sound pressure level LAeq,Tismeant. See also Zx.5 and Annex Zx. 48 / 65

49 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, andautomatically 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 programmed simulation noise described in EN ; 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 , while playing the fixed programmed simulation noise described in EN 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 programmed simulation noise, the warning does not need to be given as long as the average soundpressure of the song is below the basic limit of 85dBA. In this case T becomes the duration of thesong. NOTE 4 Classical music typically has an average soundpressure (long term LAeq,T) which is much lower than the averageprogrammed simulation noise. Therefore, if the player is capabletoanalyse the song and compare it with the programmed 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 programmed 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. ZX.3 Warning 49 / 65

50 The 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 5mm; and the following wording, or similar: To prevent possible hearing damage, do not listen at high volume levels for long periods. Figure 1 Warning label (IEC ) Alternatively, the entire warning may be giventhrough the equipment display during use, when theuser is asked to acknowledge activation of thehigher level. ZX.4 Requirements for listening devices (headphones and earphones) ZX.4.1 Wired listening devices with analogue input: With 94 dba sound pressure output LAeq,T, the inputvoltage of the fixed programmed simulation noise described in EN shall be 75 mv. This requirement is applicable in any mode wherethe headphones can operate (active or passive),including any available setting (for example built-in volume level control). NOTE The values of 94 dba 75 mv correspond with 85dBA 27 mv and 100 dba 150 mv. ZX.4.2 Wired listening devices with digital input: With any playing device playing the fixed programmed simulation noise described in EN (and respecting the digital interface standards, where a digital interface standard exists that specifies the equivalent acoustic level), the acoustic output LAeq,T of the listening device shall be 100 dba. This requirement is applicable in any mode where the headphones can operate, including any available setting (for example built-in volume level control, additional sound feature like equalization,etc.). NOTE An example of a wired listening device with digital input isa USB headphone. 50 / 65

51 ZX.4.3 ZX.5 Annex Zx (informative) Wireless listening devices: In wireless mode: with any playing and transmitting device playing the fixed programmed simulation noise described in EN ; and respecting the wireless transmission standards, where an air interface standard exists that specifies the equivalent acoustic level; and with volume and sound settings in the listening device (for example built-in volume level control, additional sound feature like equalization, etc.) set to the combination of positions that maximize the measured acoustic output for the above-mentioned programmed simulation noise, the acoustic output LAeq,T of the listening device shall be 100 dba. NOTE An example of a wireless listening device is a Bluetooth headphone. Measurement methods: Measurements shall be made in accordance with EN or EN as applicable. Unless stated otherwise, the time interval T shall be 30 s. NOTE Test method for wireless equipment provided without listening device should be defined. Significance of LAeq,T in EN and additional information 51 / 65

52 LAeq, T is derived from the general formula for equivalent sound pressure: This can be represented graphically as follows: In EN the measurement time interval (t2 t1) is 30 s. In practice, and for the purposes of listening to personal music player content, LAeq,T has a time interval T (t2 t1) in the order of minutes / hours and not seconds. 6.5 (Limitation value) of EN :2000 acknowledges this fact and states that the 100 db limit equates to a long time average of 90 db LAeq,T. By using the IEC programmed simulation noise test signal, this also takes the spectral content into account. The SCENHIR1 report states that 80 dba is considered safe for an exposure time of 40 h/week. Most persons do not listen to 40 h/week to their personal music player. In addition, not all music tracks are at the same level of the simulated noise signal. Whilst modern music tends to be at around the same level, most of theavailable music is at a lower average level. Therefore, the working group2 considers a value of 85 dba to be safe for an overwhelming majority of the users of personal music players. 52 / 65
