The point is, what is the unit for Loudness (Sones (N) or Phons (L))?

Phons are not the units for loudness, they are for loudness level, and they are just units to compensate the perception dependency on frequency.

Neither are used in metrology.

Thanks for the correction - and confirmation.

A confirmation would be to show an industry-standard mixer calibrated in sones / phones. There are none.
