摘要

在本文中，我们研究了是否可以通过相互比较来自一个源和另一个源的声音来判断距离。我们进一步打算将这种声音比较与相对距离联系起来。结果表明，声音响度与距离具有良好的相关性。换句话说，可以通过将听到的声音与标准声音进行比较来估计距离。对于考生听到的声音与距离的关系，一致性指数较好，相关性一致。随着距离的增加，声音响度急剧下降，低至1m左右，超过1m后声音响度缓慢下降

Relation between distance and pressure of acoustic signal

In this paper, we investigated if the distance can be judged by mutually comparing sound from a source with that from another. We further intended to correlate this sound comparison with the relative distance. It was made clear from the result that the sound loudness exhibited good correlation with the distance. In other words, the distance can be estimated by comparing the sound heard with the standard sound. As for the relation between the distance and the sound heard by the examinee, the consistency index was good and the correlation was consistent. The sound loudness sharply fell with distance, down to about 1 m, and slowly decreased beyond this distance.<>
