BS EN 50332-3 discusses sound system equipment with a focus on headphones and earphones associated with personal music players maximum sound pressure level measurement methodology. BS EN 50332-3 is the third part of the BS EN 50332 multi-series on sound system equipment that specifies sound dose measurement, and the alerts associated, to reduce the risk of listeners developing hearing impairment when using a Personal Music Player (PMP).
Note: BS EN 50332-3 does not cover exposure from other sources than PMPs.
BS EN 50332-3 on measurement method for sound dose management is useful for:
Sound exposure assessment is done with a normalized dosimeter located close to the head (ears) of the user during the whole time of the exposure. However, in the context of leisure activities, and for evident practical and economical reasons, this ideal methodology cannot be applied.
BS EN 50332-3 aims to provide the users with an alternative and more applicable methodology for estimating sound exposure from PMPs. BS EN 50332-3 discusses limits and calibration, headset Type variations, headset Fit-variation, testing, a test of PMP with headphones/plugs included, a test of PMP with headphones/plugs not included, an example of how the basic protections could be achieved, Loudness Normalization and EBU R128, and sound of non-PMP origin.
