Echolocation call parameters of Daubenton's bats during exposure to masking noise

The dataset consists of echolocation call parameters from Daubenton's bats (Myotis daubentonii). These calls were recorded with an array of seven microphones during controlled behavioural experiments in which the bats were exposed to four different levels of broadband, ultrasonic noise. The task that bats were trained to complete was to fly across an anechoic room while using echolocation and land on a spherical transducer that could emit the noise.

本数据集收录道本顿鼠耳蝠（Myotis daubentonii）的回声定位叫声（echolocation call）参数。该数据集的叫声样本通过七麦克风阵列在受控行为实验中录制得到，实验期间蝙蝠被置于四种不同强度等级的宽带超声噪声（broadband ultrasonic noise）环境中。实验训练蝙蝠完成的任务为：在利用回声定位的前提下飞越消声室（anechoic room），并降落在可发射噪声的球形换能器（spherical transducer）上。

背景与挑战

背景概述

该数据集记录了道氏鼠耳蝠在暴露于不同水平宽带掩蔽噪声时的回声定位叫声参数。数据集包含在受控行为实验中收集的声学数据，蝙蝠在噪声环境中执行回声引导着陆任务，研究人员通过麦克风阵列记录并分析了叫声参数变化。数据集揭示了蝙蝠通过微弱的隆巴德效应（叫声强度随噪声增加而轻微增强）来应对噪声干扰，即使在不利的信噪比条件下仍能完成导航任务。
