Personal music players shall be designed and manufactured in a manner
that ensures that, under reasonably foreseeable conditions of use, they
are inherently safe and do not cause hearing damage.

(1) Exposure to sound levels shall be time limited to avoid hearing
damage. At 80 dB(A) exposure time shall be limited to 40 hours/week,
whereas at 89 dB(A) exposure time shall be limited to 5 hours/week. For

foreseeable use of the products.
(2) Personal music players shall provide adequate warnings on the risks
involved in using the device and to the ways of avoiding them and information
