Hum Frequency by Country

AN-7

 

The following table may be found useful as aid in authenticating the country of origin of a particular audio recording.  It can also be used to focus in on the line frequency on a particular recording if the country of origin is known. It is strictly useful as “knock-out” criteria of a suspect recording.  For example, if a recording is said to have been produced in a country having a line frequency of 50 Hz and 60 Hz is the only frequency found, then its stated origin is suspect. This table is designed to be used in conjunction with the Diamond Cut Spectrum Analyzer in high-resolution mode.  For more details, please refer to the Spectrum Analyzer section of your Users Manual.  Lastly, the AC RMS Line Voltages are included in case you need to travel to one of these countries to testify as an expert witness.  This will help you assure that any electronic equipment that you will be traveling with will be compatible with the AC mains of your destination country.

Note: 1 Hz = 1 CPS (Cycle per Second)
