Students install sensors in a tree on the Homewood campus.<\/figcaption><\/figure>\n

In spring, Johns Hopkins\u2019 Homewood campus is a symphony of chirping birds, students chattering, and the hum of lawnmowers and hedge trimmers. To a group of engineering students, this pleasant auditory chorus is more than background noise: It\u2019s an opportunity to use acoustic sensors to learn more about avian life on campus.<\/p>\n

The electrical and computer engineering undergraduates installed a network of devices in trees on campus. These sensors use radio links to transmit data about sound sources, rather than actual audio, according to Andreas Andreou<\/a>, professor of electrical and computer engineering<\/a> and project mentor.<\/p>\n

\u201cWhat we are doing in this Homewood Soundscape project is monitoring birds and learning about the types of birds on campus: basically, deciphering their chirps and calls and turning it into meaningful data.\u201d<\/p>\n

The project combines sensory systems, embedded processing, and machine learning: all crucial electrical and computer engineering concepts. Eventually, the students plan to expand the project to include other sensors, including those that measure water quality in the surrounding streams.<\/p>\n

\u201cUltimately, this marriage of Internet of Things (IoT) technology and environmental monitoring showcases JHU’s dedication to harnessing the power of technology for the betterment of its community and beyond,\u201d Andreou said.<\/p>\n","protected":false},"excerpt":{"rendered":"
