据介绍，由于缺乏这些物种的听力信息，预测和减轻人为海洋噪音对海洋动物的影响受到阻碍。
研究人员制定了一个捕获和释放计划，在夏季迁徙期间临时扣留幼年小须鲸进行听力测试。2023年，两头小须鲸提供了听觉脑干反应的测量结果和听力频率范围的数据。
结果表明，小须鲸对高达45至90千赫的声音频率很敏感。这些测试提供了可能影响小须鲸和其他相关须鲸物种的人为噪音类型的信息。

Abstract: Predicting and mitigating the impacts of anthropogenic ocean noise on marine animals is hindered by a lack of information on hearing in these species. We established a catch-and-release program to temporarily hold adolescent minke whales (Balaenoptera acutorostrata) for hearing tests during their summer migration. In 2023, two minke whales provided measures of the auditory brainstem response and data on the frequency range of their hearing. Results show that minke whales are sensitive to sound frequencies as high as 45 to 90 kilohertz. These tests provide information on the types of anthropogenic noise that could affect minke whales and potentially, other related baleen whale species.
