The Earthsound Project News en-us Copyright 2017 JT Bullitt 2017-08-21T04:35:27+01:00 jt bullitt What's new Welcome, Antarctica You can now listen to the seismic sounds of Earth, from a seismometer at Casey Station in the Australian Antarctic Territory. The world in your hands From the home page You can now explore the audio streams in two new ways: using a map of the world (click on the station you'd like to hear) or a slowly spinning globe (sit back and listen, or reorient the globe by mouse, if you like). As you explore this site, you may also notice hints here and there of one of this project's long-term aspirations: to embrace audified signals from many different kinds of detectors around the world. We live immersed in a shimmering sea of energy -- seismic waves, infrasound, gravitational waves, colliding subatomic particles... Perhaps when all these ubiquitous energies are made audible we will, through listening, rediscover our long-lost natural state: unbounded astonishment. A multitude of streams After several months of computer coding and audio engineering shenanigans, I'm now able to generate up to four near-real-time stereo Earthsound streams simultaneously from a single Mac Mini (a 'pod'). More pods are on the way, each one streaming four stations from the IRIS/IDA network of global seismometers. Soon you'll be able to explore the sounds of the Earth as never before. The complexity of all this is new for me; occasional glitches, hiccups, and downtime are to be expected. If the site doesn't seem to be working properly one day, I hope you'll try again the next. Never give up trying to listen to the Earth! Sleep improvement through silence I finally removed the brief audio chime between the program segments. The chime was originally introduced to help listeners synchronize their ears to the left edge of the spectrogram image. It turns out that most people did not find this audio cue helpful; even with the chime it can be maddeningly difficult to follow along with the spectrogram. Also, some listeners who occasionally enjoy dozing off to sleep while listening to the sounds of Earth perceived the chime as an unwelcome interruption. New stream added Introducing the near-real-time sounds from seismic station WRAB in Tennant Creek, Australia. Situated in a remote corner of the Outback, far from any coastal microseismic sources, WRAB is one of the quietest stations of the global IRIS/IDA network. In this audio stream, the two horizontal components of ground motion are panned to the left and right audio channels, creating a deliciously wide stereo image.
