Creating a baseline understanding of communicative signals and perceptual abilities is imperative for gaining insight into a species' life history. This is especially relevant for at-risk species, as it can aid in monitoring and conservation efforts. Marine mammals communicate predominately through acoustic modalities for a variety of functions, including foraging and reproduction. The acoustic signals produced by marine mammals, and their ability to perceive signals produced by conspecifics, are directly impacted by the level of ambient noise in the underwater environment in which they inhabit. Modern ocean noise levels are considerably louder than historical levels, and noise is therefore considered to be a threat to acoustically communicating marine mammal species. This review summarizes the documented acoustic signals, hearing abilities, and responses to sound of a critically endangered baleen whale, the North Atlantic right whale (Eubalaena glacialis), highlights gaps in the current body of literature, and identifies priorities for future research.
建立对交际信号和感知能力的基本了解对于深入了解物种的历史至关重要。这对于濒危物种尤其重要，因为它有助于监测和保护工作。海洋哺乳动物主要通过声学模式进行交流，用于各种功能，包括觅食和繁殖。海洋哺乳动物发出的声信号及其感知同种生物发出的信号的能力，直接受到其栖息的水下环境中环境噪声水平的影响。现代海洋噪声水平比历史水平高得多，因此噪声被认为是对通过声音进行交流的海洋哺乳动物物种的威胁。本综述总结了记录在案的北太平洋露脊鲸（Eubalaena glacialis）的声学信号、听力能力和对声音的反应，突出了当前文献中的空白，并确定了未来研究的优先事项。
