Personal music players can expose their listeners to high sound pressure levels over prolonged periods of time. The risk associated with prolonged listening is not readily available to the listener, and efforts are made to standardize dose estimates that may be displayed for the user. In the present paper, the signiﬁcance of including the speciﬁc sensitivity and frequency response of the earphone type is considered, and a proposal for a revised approach to the implementation of such standardized estimates is assessed. The study is based on simulation of given use-case scenarios using earphone measurements published in the past. The work is on-going.
