Claims20
A hearing aid comprising:
- a first wireless interface communicating via a first antenna element, the first wireless interface configured to operate at a first operational frequency,
- a second wireless interface configured to communicate via a first coil,
- a power source configured to provide power to components of the hearing aid,
- wherein the hearing aid is configured to charge a transmitter part of the first wireless interface according to a charge profile, and where the charge profile defines a relation between charged power level and time, the charge profile defining a charge rate being in the range of 2.5 mA/microsecond to 4 mA/microsecond, wherein the first wireless interface comprises a capacitor configured to be charged according to the charge profile.
