The exposure by personal music players may in future be displayed to users, as described in the current draft of EN 50332-3. The suggested procedure includes a weighting of the electrical output voltages of the music player, and does not include the significance of the earphone sensitivity. It does not include the weighting principles necessary for sound sources close to the ears either, which constitutes an inverse head-related transfer function for the free- or diffuse field. The purpose of the present study is to assess the uncertainties in the dose estimate determined this way. Measurements for 20 earphones are included, and free- and diffuse field equivalent levels determined according to ISO 11904-2.
