    hello , I have an experiment that i have to design , this is the problem statement :
    "Most of Mobile telephone users encounter noise and interference from speakers of PCs at frequencies less than 20kHz. This is generally observed during an incoming call" , my question what is the range of frequency because i searched alot and didn't find any answer

    My impression is that the quote is garbled.

    It's most likely supposed to be understood more like this:
    "PC speakers picks up noise and inteference below 20 kHz from nearby cellphones, especially when a call is received from said phones."
