BS EN 50332-2:2013
This standard BS EN 50332-2:2013 Sound system equipment: Headphones and earphones associated with personal music players. Maximum sound pressure level measurement methodology is classified in these ICS categories:
- 33.160.50 Accessories
- 17.140.50 Electroacoustics
This Part 2 of EN 50332 specifies methods of measuring the matching values for the use of personal music players and headphones/earphones defined for the use with those and with standardised connectors or interfaces allowing to combine components of different manufacturers or different design sold separately in order to avoid possible hearing impairment by excessive sound pressure resulting from them.
Compared with “one-package sets” the sound pressure level at the ear cannot be fixed by only one condition but needs at least two characteristics, one each for player and the headphones/earphones, defined by the matching values for their connection.
Requirements for protection against excessive sound pressure from personal music players are given in EN 60950-1:2006/A12:2011 and EN 60065:2002/A12:2011.
