DECAF - AUTEC Beaked Whales - Single Sensor case study

Original provider: Density Estimation of Cetaceans from passive Acoustic Fixed sensors (DECAF) Abstract: These data were used to characterize the performance of the automatic detector. A 6-minute recording from hydrophone 57 was manually checked for beaked whale clicks. This 6-minute section was part of the main 6-day dataset used in the case study. The automatic detector was used on the same sound file, and the results compared. For each manually detected click, the signal-to-noise ratio (SNR) was calculated, the quality of the click was judged and it was noted whether or not the click was detected by the automatic detector.原始数据提供者：基于被动声学固定传感器的鲸类密度估计算法（Density Estimation of Cetaceans from passive Acoustic Fixed sensors, DECAF） 摘要： 本数据集用于表征自动检测器的检测性能。研究人员对编号为57的水听器录制的一段6分钟音频片段进行人工核查，以甄别喙鲸咔哒声。该6分钟片段属于本次案例研究所用的核心6天数据集的一部分。随后将自动检测器应用于同一段音频文件，并对二者的检测结果进行比对。针对每一个人工检出的咔哒声，研究人员计算了其信噪比（Signal-to-Noise Ratio, SNR），对该咔哒声的质量进行评判，并记录该咔哒声是否被自动检测器成功检出。
