One of the method to treat the voice loudness quantitatively is Loudness Rating method. It is determined by loudness balance between reference voice which passes through wide and flat frequency characteristic transmission system, and within subject. These variation is considered to be caused by auditory psycological factors. This paper reports these factors influence, such as, listening level, timbre difference, presentation interval, and level variation in voice duration time to the measurement value variation. From this investigation, it is confirmed that the most dominant and sensitive factor is the timbre difference between reference and measured voice due to these transmission sensitivity frequency characteristic difference. But, if band limitation is introduced to the measurement, it makes the timbre differnce decrease and consequently measurement variation decrease. These results can be adopted to the telephone transmission rating which uses the same loudness balance method, and will make the measurement accuracy increase.
