The effect of temporal and spatial aspects of sounds on the loudness was investigated, and the result suggests the followings:1) It was made clear that the loudness of various sounds from various directions can be evaluated by an energy summation model (Leq), as a first approximation. 2) Among mixed sound sources, a prominent sound (e.g. a meaningful sound, or a moving sound) tend to become "figure" (S), and other sounds tend to become "background" (N). The loudness of "figure" sound is determined by S/N. 3) When "figure" and "backgound" sounds are presented from different directions, the "figure" sound is judged as being louder than when both sounds are presented from the same direction. 4) A moving sound is not always perceived as being louder than a fixed sound. However, it can be louder if its movement attracts attention. 5) When various sounds are monaurally presented, their loudness is determined by Leq, and spatial factors in the presentation has little effect on the loudness. 6) The dynamic characteristics of hearing was investigated using non-steady state sounds. The result was different between monaural and dichotic presentation of the sounds, which suggests the overshoot at the onset of the stimulus may be due to the effect temporal masking.Further investigation is needed in order to draw a general conclusion.

研究了声音的时间和空间方面对响度的影响，结果表明：1）明确了来自不同方向的各种声音的响度可以通过能量求和模型（Leq）作为第一近似值来评估。 2）在混合声源中，突出的声音（例如有意义的声音或移动的声音）往往会成为“人物”（S），而其他声音往往会成为“背景”（N）。 “数字”声音的响度由S/N决定。 3)当“人物”和“背景”声音从不同方向呈现时，“人物”声音被判断为比两个声音从相同方向呈现时更大。 4) 移动的声音并不总是被认为比固定的声音更大。然而，如果它的动作引起注意，声音可能会更大。 5)当各种声音单声道呈现时，其响度由Leq决定，呈现时的空间因素对响度影响很小。 6）利用非稳态声音研究了听力的动态特性。声音的单耳和双耳呈现之间的结果是不同的，这表明刺激开始时的过冲可能是由于时间掩蔽效应造成的。需要进一步研究才能得出一般结论。
