Binaural hearing and time window in the transient

It was reported that in the early stage of monaural hearing, the hearing system has an interfering transient response on loudness to the 0. 05 ms rectangular pulse excitation and there the loudness to each pulse is added having its sign. However, at binaural hearing, the loudness of two pulses of different signs from the opposite lateral directions was summed in the absolute manner and it was almost the same as the loudness of two rectangular pulses in the same sign or a single pulse of double the amplitude from one lateral direction. Loudness of reflected sound fields caused by two different sized plane panels having the direct pulsive sound were compared. The loudness difference between them was not explained by the difference of the largest instantaneous loudness, but was done by the integration of the loudness amplitude in the time window. In the last, the transient process on the hearing system for the loudness of 0. 05 ms rectangular pulse was summarized with new understandings in the earlier and present paper.
