ABSTRACT:
At least one exemplary embodiment is directed to a method of monitoring hearing health comprising: measuring a first acoustic sound pressure level due to an ambient audio signal; measuring a second acoustic sound pressure level due to an emitted audio signal from a speaker; calculating a total sound pressure level dosage, where the total sound pressure level dosage is calculated using the first acoustic sound pressure level and a first time span, and the second acoustic sound pressure level and a second time span associated, where the first time span is the time associated with the measured first acoustic sound pressure level and second time span is the time associated with the measured second acoustic sound pressure level; and sending a notification signal when total sound pressure level dosage is greater than a threshold value.
