Abstract

Field measurements of sound propagation in a humpback whale habitat were collected to identify cues that a humpback whale might use to estimate its distance from sound sources. The data show that spectral cues are sufficient for estimating the relative distance a sound has traveled in such environments, and that several other cues may also provide useful information. It is suggested that listening humpback whales may use multiple cues in parallel to determine the range to singing whales.

摘要

收集了座头鲸栖息地声音传播的实地测量数据，以确定座头鲸可能用来估计其与声源距离的线索。数据表明，频谱线索足以估计声音在此类环境中传播的相对距离，并且其他一些线索也可能提供有用信息。有人提出，正在倾听的座头鲸可能会同时使用多种线索来确定与正在唱歌的座头鲸之间的距离。
