Dear Sir/Madam, In this requirement, there is a following exemption.
analogue personal music players (personal music players without any kind of digital processing of the sound signal) that are brought to the market before the end of 2015. NOTE 4 This exemption has been allowed because this technology is falling out of use and it is expected that within a few years it will no longer exist. This exemption will not be extended to other technologies. I believe the old design portable DVD players with a pair of earphones and operated on batteries or rechargeable batteries are qualified for such exemption. I am seeking advice why the digital processing of sound signal is so critical to this sound pressure restriction and how to identify if the digital processing is built in the unit or not.
