Dolphins use frequency-modulated whistles for a variety of social functions. Whistles vary in their characteristics according to context, such as activity state, group size, group composition, geographic location, and ambient noise levels. Therefore, comparison of whistle characteristics can be used to address numerous research questions regarding dolphin populations and behaviour. However, logistical and economic constraints on dolphin research have resulted in data collection biases, inconsistent analytical approaches, and knowledge gaps. This Data Descriptor presents an acoustic dataset of bottlenose dolphin (Tursiops aduncus) whistles recorded in the Fremantle Inner Harbour, Western Australia. Data were collected using an autonomous recorder and analysed using a range of acoustic measurements. Acoustic data review identified 336 whistles, which were subsequently measured for six key characteristics using Raven Pro software. Of these, 164 'high-quality' whistles were manually measured to provide an additional five acoustic characteristics. Digital files of individual whistles and corresponding measurements make this dataset available to researchers to address future questions regarding variations within and between dolphin communities.
海豚使用调频口哨来进行各种社交功能。口哨的特征会根据情境而有所不同，例如活动状态、群体大小、群体组成、地理位置和环境噪声水平。因此，比较口哨的特征可以用来解决有关海豚种群和行为的许多研究问题。然而，海豚研究受到后勤和经济方面的限制，导致了数据收集的偏差、分析方法的不一致和知识空白。本数据描述符提供了一个在澳大利亚西部弗里曼特尔内港记录的宽吻海豚（Tursiops aduncus）口哨声的声学数据集。数据是使用自主记录器收集的，并使用一系列声学测量进行了分析。对声学数据的审查确定了 336 个口哨声，随后使用 Raven Pro 软件对六个关键特征进行了测量。其中，164 个“高质量”口哨声被手动测量，以提供另外五个声学特征。每个口哨声的数字文件和相应的测量值使该数据集可供研究人员使用，以解决有关海豚社区内部和之间变化的未来问题。
