4.2 Performance
4.2.1 Maximum sound pressure levels generated by entertainment audio
4.2.1.1 General
The equivalent sound output levels of the test samples shall be tested in accordance with the appropriate procedure from EN 13819-3:2019 (7.4.3, 7.5.2 or 7.6.2) and reported in the test report. The mean value of eight measurements plus one standard deviation shall not exceed 82 dB(A). In cases where a manulacturc’r has designed left and right earplugs in a different way (especially in terms of sound pressure level effective to the ear), neither the mean value of four measurements of left earplugs plus one standard deviation nor the mean value of four measurements of right earplugs plus one standard deviation shall exceed 82 dB(A).
4.2.1.2 Earplugs with built-In broadcast receivers for FM radio
The procedure from EN 13819-3:2019, 7.4.3 shall be used. The sound output levels are determined for the FM radio signal defined in EN 13819-3:2019. 7.4.3.1 with one specific signal level.
4.2.1.3 Entertainment audio earplugs with electrical audio input
The procedure from EN 13819-3:2019, 7.6.22.2 shall be used. The sound output levels shall be measured up to 150 mV or up to the maximum input voltage as specified by the manufacturer (whichever is larger).
NOTE 1 This requirement corresponds o the maximum output voltage of a personal music player ol iSO mV according to EN 62368-1:20 14.AC:2015, 10.6.2.2 it the test signal from EN 50332-1:20 13 is applied.
NOTE 2 EN 50332-1:2013 and EN 50332-2:2013 contain the test procedures ror the maximum sound pressure levels olpersonal music players.
4.2.1.4 Entertainment audio earplugs with built-in Bluetooth receivers
The procedure from EN 13819-3:2019, 7.5.2 shall be used. The sound output levels are determined for the Bluetooth signal defined In EN 13819-3:2019. 7.5.2.2.2.
4.2.1.5 Complete systems composed ol transmitters and entertainment audio earplugs
EN 13819-3:2019, 5.2 or5.3 and 6.5 shall be used. The transmittin receiving and amplifying devices shall be adjusted to maximum setting.
5 Marking
The marking specified In EN 352-2:2020 shall be used. No additional marking is needed.
6 Manufacturer’s Instructions and Information
The information specified in EN 352-2:2020 and the following additional information shall be supplied with the earplugs:
a) a reference to this document EN 352-10:2020;
b) an indication that the earpiugs provide an entertainment audio facility;
c) for products without electrical audio input, a statement that the earplugs provide audio signal sound pressure level limitation and that t.he earplugs limit the entertainment audio signal to 82 dB(A) effective to the ear;
d) for products with electrical audio input, a statement up to which value of input voltage (150 mv or a voltage specified by the manufacturer,whichever is larger) the entertainment audio signaldoesn’t exceed 82 dB(A) effective to the ear;
e) a warning that the product shall not be used if it can’t be ensured that the input voltage doesn’t exceed the maximum value stated in d);
f)a method of checking. charging and changing batteries, if applicable;
g)a statement that the audibility of warning signals at a specific workplace may be impaired while using the entertainment facility.
This European Standard has been prepared under a Commission’s standardization request to provide one voluntary means of conforming to essential requirements of Regulation (EU) 2016/425 of the European Parliament and of the Council of 9 March 2016 on personal protective equipment.
Once this standard Is cited in the Ofticial Journal of the European Union under that Regulation (EU) 2016/425, compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits of the scope of this standard, a presumption of conformity with the corresponding essential requirements of that Regulation (EU) 2016/425 and associated EI’TA regulations.
