This is the sound of Max Eastley's Aeolian Device at Audiograft 2013, which was exhibited in the grounds of the Headington Hill Campus at Oxford Brookes University. The sound is produced by the wind exciting some wobbly tines, arranged into a sort of wobby antennae. This device is very sensitive to the activity of the wind, and as the tines are excited by the activity of the wind, they are amplified electronically. So what you can hear is metal being excited by wind, amplified. #aeolianmap
