You added  a good  point. 

The  issue  from  variable speed motor controls   is  pretty  serious.

I live in an apartment that   upgraded     the elevator system   about    2yrs ago.

Prior  my noise level was s0 or s1

Noise level now  is   s9   all bands! for a  30ft  radius /min

Discovered  the noise source is a  Maganek600 motor controller.  Manuf. told me,  they don't  need  FCC approvals  because it has  a Canadian rating
They also told me they never had  any previous complaints  (right)

You all make a good  point,  stuff like this should  never  be allowed
