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.

达特茅斯学院获得了一个奖项，以获得一个用于跟踪视频声源的声学摄像机。声学摄像机将有助于多学科研究、教学和推广。将使用声学摄像机开发一个关于自然景观声学的教学模块，该模块可以定制并纳入研究生课程、本科生课程和专业发展日的教师培训。达特茅斯的科学&技术推广团队将协助将声学摄像机的产品提供给更广泛的社区，例如为哈伯德布鲁克LTER门户网站提供的鸣禽合唱的交互式视听节目，以及在当地科学酒吧展示的蝙蝠、青蛙和灵长类动物声学研究的电影，为国家公共广播电台关于自然界声音的特别系列节目的网站提供录音和视听展示。录音提供了关于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提供关于声源的方向或位置的信息。声学摄像机是一种先进的仪器，它集成了视觉和声学信息，通过摄像机、麦克风阵列、数据采集板和处理计算机生成视频图像，识别声音的方向和来源。在达特茅斯，有一个非常大的跨学科社区的人团结在声学和自然声音的兴趣。声学摄像机的收购将提升多个学科的多个教师的个人研究和教学计划，他们研究环境中声音的传输和识别。此外，声学摄像机将促进生物学，人类学，音乐和其他学科教师之间的跨学科合作。目前整个大学的项目解决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力学和进化驱动因素，到人类听觉，语言和音乐进化中的音景作用。在现场条件下将声音分配给聚合或成对交互中的个体的能力将使研究人员能够回答跨学科各种项目的未解决问题。
