What is BS EN 50332-1 - Maximum sound pressure level measurement of headphones about?
BS EN 50332-1 is the first part of the BS EN 50332 series on the sound system equipment with a focus on headphones and earphones associated with personal music players’ maximum sound pressure level measurement.
The scope of BS EN 50332-1 is to set up a suitable measuring methodology allowing accurate measurement of the maximum sound pressure level produced by consumers’ headphones and earphones when associated with personal music players.
Who is BS EN 50332-1 - Maximum sound pressure level measurement of headphones for?
BS EN 50332-1 on maximum sound pressure level measurement of headphones is useful for:
- Headphones and earphones manufacturers
- Personal music players manufacturers
- Music producers
- Recording studios
- Testing laboratories
Why should you BS EN 50332-1 - Maximum sound pressure level measurement of headphones use?
BS EN 50332-1 deal with sets provided as package equipment by the manufacturer. In this case, "Personal music players" means the association of one set (compact cassette player, FM radio receiver, digital media player, streaming audio player…) with supplied headphones or earphones.
BS EN 50332-1 gives guidelines to associate portable audio sets (FM radio receiver, digital media player, streaming audio player…) with headphones or earphones provided separately by any source. And the package sets with standardised connectors or interfaces between the two allowing to combine of components of different manufacturers or different designs.
The method in BS EN 50332-1 is reproducible and easily applicable to every type and shape of headphone or earphone available on the market.
As safety and health are addressed, the method in BS EN 50332-1 faithfully reflects the pressure level effective at the user's ear (good correlation with subjective tests) to support protection against excessive sound pressure from personal music players (the limits themselves are found in EN 60950-1:2006/A12:2011 and EN 60065:2002/A12:2011 respectively).
And finally, it establishes a global measuring procedure, including each component in the chain:
- Portable set
- Specific test signal
- Associated headphones or earphones.
What’s changed since the last update?
BS EN 50332-1:2013 supersedes BS EN 50332-1:2000, which will be withdrawn on 23 September 2016.
