The sidetone masking rating (STMR) is the ratio of the acoustic output signal from the receiver at the ear reference point (ERP) to the acoustic input signal at the mouth reference point (MRP) over the specified band (100 to 8000Hz). It is desirable to be constant over the receive volume control range. The frequency response measured with the Type 3.3 or 3.4 ear simulator must be transformed to the ear reference point (ERP). STMR shall be tested at the reference control, minimum, maximum volume setting.

Why don't you change the value and have a try? Let your ear feel the differences.
