Definition: the loss, expressed in decibels, constant at all frequencies transmitted, which has to be introduced into the new fundamental system for the determination of reference equivalents or NOSFER in order to obtain in a given direction the same loudness as the complete telephone connection being considered, the acoustical speech power emitted by the talker being the same in both cases

NOTE 1 – The reference equivalent is positive or negative according to whether it has been necessary for a loss to be added or removed from the NOSFER.

NOTE 2 – The reference equivalent is strictly defined by the measuring method described in the CCITT Recommendations P42 and P72 from the Volume V of the Red Book, 1985.
