1949年百慕达的座头鲸之歌, 现已成为最古老的鲸鱼声响, 在保存的塑料盘中找到。 A 1949 humpback whale song off Bermuda is now the oldest known whale vocalization, found in a preserved plastic disc.

1949年3月在百慕大附近录制的座头鲸歌曲被确认为伍兹·霍尔海洋学研究所研究人员在一个数字化项目中发现的最古老的已知鲸鱼声响。 A humpback whale song recorded in March 1949 off Bermuda has been identified as the oldest known whale vocalization, discovered by Woods Hole Oceanographic Institution researchers during a digitization project. 声音在使用灰色音像仪的声纳测试中被无意中捕获, 声音被保存在一个耐用的塑料磁盘上, Captured unintentionally during sonar tests using a Gray Audograph, the sound was preserved on a durable plastic disc—unlike fragile tapes from that era. 记录为研究现代人类制造的噪音如何影响鲸鱼的通讯、航行和行为提供了一个基线。 The recording offers a rare glimpse into the ocean’s quieter 1940s soundscape, providing a baseline for studying how modern human-made noise affects whale communication, navigation, and behavior.
