A power spectrum plot will tell him he has a 60Hz hum. I think he already knows that. I think he can definitely consider solutions
without following your suggestion. :-)
No, It's not a "60Hz hum". Yes, 60Hz is getting into the line
but the existing filters are removing the 60hz. What he hears
is most likely 120Hz, 240Hz or something else or most likely
a combination of various multiples for 60hz. I'd bet that the tiny speaker inside a telephone handset can not
even reproduce a 60Hz tome. Yes you can hear a hum but it's
the overtomes of 60 that you hear. Many people can not even hear
down to 60Hz, some can but not everyone.
