Sound system equipment: Headphones and earphones associated with portable audio equipment - Maximum sound pressure level measurement methodology and limit considerations -- Part 1: General method for "one package equipment"
The scope of this standard is to set up a suitable measuring methodology allowing accurate measurement of the maximum sound pressure level produced by consumer's headphones and earphones when associated with portable audio equipment. NOTE This standard does not apply to acoustically open or acoustically closed headphones associated with mains operated Hi-Fi home equipement nor does it apply to headphones for medical purposes (hard of hearing etc.) or to headphones or similar parts being part of active hearing protection systems. Wireless headphones are neither included, conditions for them may be derived accordingly. Other requirements for safety, e.g. for noise protection in offices and industry are not affected by this standard. Requested features: ? The method should be reproducible and easily applicable to every type and shape of headphone or earphone available on the market (good mechanical adaptability). ? As safety and health are addressed, the method should faithfully reflect the pressure level effective at the user's earhig (good correlation with subjective tests). -
