The equipment requested in this proposal will enable me to make use of recent advances in sound synthesis software and miniaturized high sample rate acquisition hardware to simultaneously broadcast sounds and neurologically record the auditory responses of insects.  My laboratory investigates the auditory neurophysiology and sensory ecology of insect ears, primarily moths and grasshoppers to the echolocation calls of insectivorous bats.  Bats emit an astonishing diversity of high frequency sounds and reproducing these sounds in an accurate fashion that also allows me to manipulate particular acoustic variables is now possible using a customized MATLAB application that I am in the process of developing.  The sound recording company Avisoft manufactures high frequency microphones and speakers that will enable me to reproduce the sounds of unusual bat species found in tropical regions of the world where I have either previously studied or am planning to study in the future.  Testing moth ears against these complex sounds will allow field trips to the areas where these bats are found (e.g., South Africa, Australia, South America).  Avisoft's digital data acquisition system can also be used to record the echolocation calls of wild bats in their natural habitats as well as the auditory neural activity of the insects that listen for them.  This will now be possible using a field-compatible workstation that is battery operated via USB connections and fully portable.

本提案中要求的设备将使我能够利用声音合成软件和小型化高采样率采集硬件的最新进展，同时广播声音并从神经学角度记录昆虫的听觉反应。  我的实验室研究昆虫耳朵（主要是飞蛾和蚱蜢）的听觉神经生理学和感觉生态学以及食虫蝙蝠的回声定位呼叫。  蝙蝠发出的高频声音种类繁多，令人惊叹，并且可以使用我正在开发的定制 MATLAB 应用程序以准确的方式再现这些声音，这也使我能够操纵特定的声学变量。  录音公司 Avisoft 生产高频麦克风和扬声器，使我能够重现在我以前研究过或计划将来研究的世界热带地区发现的不寻常蝙蝠物种的声音。  针对这些复杂的声音测试蛾耳将允许前往发现这些蝙蝠的地区（例如南非、澳大利亚、南美洲）进行实地考察。  Avisoft 的数字数据采集系统还可用于记录野生蝙蝠在自然栖息地中的回声定位叫声以及聆听它们的昆虫的听觉神经活动。  现在可以使用现场兼容的工作站来实现这一点，该工作站通过 USB 连接进行电池供电，并且完全便携。
