Methods of operating an audio device are provided. A method includes calculating estimated sound pressure levels (SPLs) for drive signals directed to an ear canal receiver (ECR) during a time increment Δt calculating an estimated SPL_Dose during the time increment Δt using the estimated sound pressure levels and calculating a total SPL_Dose at a time t of the audio device using the estimated SPL_Dose.
