Patris, Malige, Glotin, Asch, and Buchan [(2019). Acoust. Soc. Am. 146, 2145-2154] proposed a technique for classifying and describing pulsed sounds produced by whales that can improve the precision and objectivity of acoustic measurements from song units. Their analyses revealed that blue whales produce units at precise pulse rates. The structure and precision of the song phrase they describe is remarkably similar to what is seen in song production by chickadees. In both species, precise control of shifts in pulse rate may produce reverberation-related cues that enable listeners to localize singers. The techniques developed by Patris and colleagues thus can provide more accurate measures as well as insights into how animals produce and use songs.
帕特里茨、马利格、格洛廷、阿施和布坎 [(2019)。美国声学学会杂志，146，2145-2154] 提出了一种分类和描述鲸鱼发出的脉冲声音的技术，这可以提高来自歌曲单元的声学测量的精度和客观性。他们的分析表明，蓝鲸以精确的脉冲率产生单元。他们所描述的歌曲短语的结构和精度与山雀的歌曲生产中所看到的非常相似。在这两个物种中，对脉冲率变化的精确控制可能会产生与共鸣相关的提示，使听众能够定位歌手。因此，帕特里茨和同事们开发的技术可以提供更准确的测量结果，并深入了解动物如何产生和使用歌曲。
