Abstract:
1. Method of monitoring hearing health comprising measuring a first acoustic sound pressure level due to an ambient audio signal, using a microphone; calculating a second acoustic sound pressure level due to an emitted audio signal from a speaker, using a processor; 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, where the first time span is the time associated with the measured first acoustic sound pressure level and the second time span is the time associated with the calculated second acoustic sound pressure level, where the speaker and microphone are operatively connected into an earpiece; and sending a notification signal to the speaker when the total sound pressure level dosage is greater than a threshold value.
