Acoustic parameters for the spinner dolphins' bioacoustic sounds have previously been described. However, the dolphins in the Southwest Atlantic Ocean were only recently studied near the Fernando de Noronha Archipelago. Therefore, to contribute to additional knowledge of this cosmopolitan species, this study compares previous results with a Brazilian recording. Despite statistically significant differences, the mean value comparison indicated that Hawaiian and Southwest Atlantic Ocean spinners emit similar whistles. The fact that geographical isolation does not lead the dissemblance nor the similarity of the acoustic variations in this species raises the possibility of other factors influencing those emissions. Here those differences and similarities are discussed, thereby contributing to an understanding of how distinct populations and/or species communicate through different ocean basins.
以前已经描述过Spinner海豚生物声学声音的声学参数。然而，西南大西洋的海豚直到最近才在费尔南多·迪诺罗尼亚群岛附近进行研究。因此，为了增加对这种世界性物种的了解，本研究将以前的结果与巴西的记录进行了比较。尽管存在统计学上的显著差异，但平均值比较表明，夏威夷和西南大西洋的Spinner海豚发出的口哨声相似。地理隔离并没有导致该物种声学变化的差异或相似性，这一事实增加了其他因素影响这些发声的可能性。这里讨论了这些差异和相似性，从而有助于理解不同种群和/或物种如何通过不同的海洋盆地进行交流。
