Electromagnetic radiation at audio frequencies.

Audio frequencies are between 20Hz and 20KHz.

Audio amplifiers may emit electromagnetic radiation at audio frequencies while they are emitting sound.

According to ME3030B, electric field between 1Hz and 100KHz was below 2V/m around my audio power amplifier.

Can I assume that there is basically not much electromagnetic radiation at audio frequencies from my power amplifier?

But, I still worry about electromagnetic radiation at PWM frequencies of class-D power amplifier.
