Myth 5: 2.4 GHz is so common that other devices will cause interference with my hearing aids.
Interference is no longer an issue due to the advent of a technology called frequency hopping. Frequency hopping in simple terms means that any wireless device operating at 2.4 GHz actually searches for the most open signal within a range around 2.4 GHz (i.e. 2.39 GHz) and then transmits at that frequency. This approach of “hopping” to the most available and open signal has virtually eliminated the interference many used to experience with early cordless phones. This same approach to frequency hopping can now be found in hearing instruments and prevents annoying interference between wireless devices.
