Estimating the term…
A hearing instrument comprises a wireless communication unit interconnected with an antenna for emission and reception of an electromagnetic field having an RF wavelength, a speaker interconnected with the wireless communication unit and being configured to provide an output audio signal. A battery is configured to supply power to the hearing instrument and a filter circuit interconnects the battery and a power management circuit of the hearing instrument. The antenna extends from a feed and at least a part of the antenna being is arranged adjacent the battery. A distance between the at least part of the antenna and the battery is below 1/40 of the wavelength. The filter circuit is configured to de-couple the battery and the power management circuit at frequencies above 3 MHz and configured to connect the battery to the power management circuit at frequencies below 300 kHz.
