This sub-clause specifies requirements for
protection against excessive sound pressure from
personal music players that are closely coupled to
the ear. It also specifies requirements for

This sub-clause specifies requirements for
protection against excessive sound pressure from
personal music players that are closely coupled to

A personal music player is a portable equipment for
personal use, that:
− is designed to allow the user to listen to recorded
or broadcast sound or video; and
− primarily uses headphones or earphones that can
be worn in or on or around the ears; and
− allows the user to walk around while in use.

For music where the average sound pressure (long

) measured over the duration of the
song is lower than the average produced by the
programme simulation noise, the warning does not
need to be given as long as the average sound
pressure of the song is below the basic limit of 85
dBA. In this case T becomes the duration of the
song.

NOTE 4 Classical music typically has an average sound

to analyse the song and compare it with the programme

For example, if the player is set with the programme simulation
noise to 85 dBA, but the average music level of the song is only
65 dBA, there is no need to give a warning or ask an
acknowledgement as long as the average sound level of the
