Sammanfattning
In recent decades, an increase in the number of electromagnetic sources, such as mobile phones, has occurred in parallel with developing smaller hearing aids devices with low power consumption. All these factors have made the devices more susceptible to electromagnetic interference. It has become an important to introduce some standards and methods of measurement to create more immune hearing devices. PHONAK’s main goal of this master’s thesis is to better understand the effects of the hearing instrument (HI) parasitic microwave antenna and other non-linear HI components on the electromagnetic interference (EMI) in a HI up to frequencies of 6 GHz. This will gives the possibility to measure the immunity level of HI.
