GSM electromagnetic interference is similar.
GSM phones would transmit TDMA frames at a frequency of 217 Hz which couples with audio circuitry to cause speakers to emit a characteristic buzzing sound.
Even though it's a radio frequency signal which is outside the range of human hearing (like 800-900 MHz or higher), the signal interacts with any non-linearity in the audio circuitry (think of the diode in a crystal radio), which basically performs unintended amplitude modulation of the pulsed RF electrical signal into something like a 217 Hz square wave, which is in the audible range.
This has gone away as phones stopped using GSM. Newer standards emit more of a continuous waveform which doesn't cause these audible frequencies to be generated.
(too late to edit) I remembered this example of "unintentional amplitude modulation" of a strong AM RF signal: touching vegetation against a (presumably AM) radio mast. "Listening radio with grass"
