Reduction of emission level in approach signals of Greater Mouse-Eared Bats (Myotis myotis): No evidence for a closed loop control system for intensity compensation

Raw data wav-files recorded with an onboard microphone (telemike) with was attached on the back of the bats. With this novel method it was possible to determine the sound pressure level of emitted signals and returning echoes as received by the microphone above the nose of the flying bats.原始WAV格式音频文件由安装在蝙蝠背部的机载麦克风（telemike）录制得到。借助该创新方法，可测定飞行蝙蝠鼻部上方的麦克风所接收到的自身发射的声信号与返回回声的声压级。
