A "Google Street View" for the natural sounds of remote Australia

The Australian Acoustic Observatory project, described by its creators as a kind of "Google Street View of sound," is a new acoustic sensor network of hundreds of microphones and digital audio recorders distributed across multiple remote ecosystems on the continent. The solar-powered system will record animal and natural sounds continuously for 5 years. According to lead researcher Paul Roe of the Queensland University of Technology (QUT) Ecoacoustics Research Group and colleagues, the observatory will enable scientists and the public to listen to "a galaxy of sounds — it is like the heartbeat of the environment." While scientists will use the data to better understand the ecosystems and how they are changing over time, I bet sound artists have a (ahem) field day with the recordings once the public can listen in. From ABC News:

It was hoped citizen scientists would embrace the hidden animal world that was being captured, along with students and artists.

"For example, we will have citizen science projects where we can kind of search for a particular animal within the soundscape. People can use it to explore the environment to understand what is happening, how does the sound change," he said...

Professor Roe said 400 sensors have been placed across 100 sites in seven distinct eco-regions covering desert, grassland, shrublands and temperate, subtropical and tropical forests.

It might be then that we get birds arriving because there has been some water and trees are flowering, or there might be frogs which are going to call, they are going to come out of the desert and call after rain.

"We can't normally find out what's happening to these species, we can't predict when they are going to call, can't predict when they are going to be present.

"So by having these sensors record this data continuously, we can find out and understand how the environment is changing."
