BS EN 352-10 This document is applicable to entertainment audio earplugs. It specifies requirements on construction, design, performance, marking and user information relating to the inclusion of the entertainment audio facility.Entertainment audio earplugs use a wired or wireless system through which audio entertainment can be relayed. They may incorporate a radio receiver set or music player for entertainment or allow audio input from external devices.They also offer the possibility to communicate warning signals or messages. The product standards
impose a limitation on the reproduced sound pressure level at the ear.The entertainment audio signal can be transmitted by radio (broadcast or local plant programmes) or by wire or other communication like Bluetooth.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 manufacturer 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]. 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.Entertainment audio earplugs with electrical audio input.The procedure from EN 13819-3:2019, 7.6.2.2.2 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 to the maximum output voltage of a personal music player of 150 mV according to EN 62368-1:2014+AC:2015, 10.6.2.2 if the test signal from EN 50332-1:2013 is applied. NOTE 2 EN 50332-1:2013 and EN 50332-2:2013 contain the test procedures for the maximum sound pressure levels of personal music players.BS EN 352-10 pdf download.
