MRI: Acquisition of an Acoustic Camera for Multidisciplinary Research and Teaching at Dartmouth College

达特茅斯学院获得了一项奖励，以获得用于跟踪视频声源的声学摄像机。声学相机将有助于多学科的研究，教学和推广。将开发一个使用声学相机的自然景观声学教学模块，可以定制并纳入研究生课程，本科课程和教师培训的专业发展日。达特茅斯的科学与技术拓展团队将协助将声学相机的产品传递给更广泛的社区，例如为哈伯德布鲁克LTER门户网站提供关于鸣禽合唱的交互式视听描述，为当地科学酒吧提供关于蝙蝠、青蛙和灵长类动物声学研究的电影，以及为国家公共广播电台的网站提供关于自然声音特别系列的视听展示。录音提供了有关自然系统和人类环境的丰富信息。然而，声学记录的一个主要限制是它们不能提供有关声源方向或位置的信息。声学相机是一种尖端的仪器，它将视觉和声学信息结合起来，通过摄像机、麦克风阵列、数据采集板和处理计算机来生成识别声音方向和来源的视频图像。在达特茅斯，有一个非常庞大的跨学科社区，人们因为对声学和自然声音的兴趣而团结在一起。声学摄像机的购置将提升多学科多学院的个人研究和教学计划，他们研究环境中声音的传播和识别。此外，声学相机将促进生物学、人类学、音乐和其他学科教员之间的跨学科合作。目前，整个大学的项目都在研究声音在进化过程中的作用。这些项目的范围从声学信号动物的社会互动的动态和进化驱动因素，到声景在人类听觉、语言和音乐进化中的作用。在现场条件下，将声音分配给群体中的个体或成对交互的能力将使研究人员能够回答跨学科各种项目中未解决的问题。

An award is made to Dartmouth College to acquire an acoustic camera for tracking sources of sound in video. The acoustic camera will contribute to multidisciplinary research, teaching and outreach. A teaching module will be developed on the acoustics of natural landscapes using the acoustic camera that can be customized and incorporated into graduate courses, undergraduate courses and teacher training for professional development days. Dartmouth's Science & Technology Outreach team will assist with delivering products from the acoustic camera to the broader community, such as interactive audiovisual depictions of songbird choruses for the Hubbard Brook LTER web portal, movies from research on the acoustics of bats, frogs and primates to present at a local science pub, and audiovisual displays for the website of a National Public Radio special series on sounds in nature.Sound recordings provide rich information about natural systems and human environments. A major limitation of acoustic recordings, however, is that they do not provide information about the direction or location of the sound source. An acoustic camera is a cutting-edge instrument that integrates both visual and acoustic information to generate video images that identify the direction and source of sounds using a video camera, microphone array, data acquisition board and processing computer. At Dartmouth, there is an unusually large and interdisciplinary community of people united by an interest in acoustics and natural sounds. The acquisition of an acoustic camera will elevate the individual research and teaching programs of multiple faculty in multiple disciplines who study the transmission and identity of sounds in the environment. Furthermore, the acoustic camera will foster cross-disciplinary collaborations among faculty in Biology, Anthropology, Music, and other disciplines. Current projects across the university address the role of sounds in evolutionary processes. These projects range from the dynamics and evolutionary drivers of social interactions in acoustically signaling animals, to the role of soundscapes in the evolution of human hearing, language and music. The ability to assign sounds to individuals within aggregations or pairwise interactions in field conditions will enable researchers to answer unresolved questions for a variety of projects across disciplines.
