Abstract

A first temperature sensor (5) is located in the unit for placing inside the ear canal, whilst a second temperature sensor (4) is located outside the ear of the person using the hearing aid. The device comprises a unit for placing inside the ear channel, and a battery. A temperature difference is measured between two sensors in order to compensate for the thermoelectric energy consumption of the battery.
