Sound and Science symposium UCLA

Friday, March 6th, 2009

A fascinating collection of presentations by scientists and artists working with sound and sonification. Video streams of the lectures at Sound and Science

Prof Peter Narins presented research discoveries on the ultrasonic calls and hearing of certain frogs to adapt to environmental noise. The spectograms of the sound recordings clearly show how limited our own hearing range is in the total sound scape we inhabit. He implied that ultrasound is a relatively new and unexplored area of science, and put the recent interest down to now available field technology, such as the Sound Devices 722 that he used on a field trip in China.

Laura Peticola presented work using sound to communicate data about solar winds. As a space scientist she described the need and difficulties of making the concepts of solar storms, magnetic fields and even plasma to a general public. The team decided to use sound, rather than visualisation, to create sonifications of live solar wind data received by two satellites orbiting the sun. (more…)

experiments in underwater sound

Friday, March 6th, 2009

The first presentation of new material related to underwater sounds, at the Karnatic Lab evening, De Badkuyp, Amsterdam. I was interested to use the opportunity of an informal but public lab setting to put together a live performance that relates environmental recordings of underwater mammal sounds, electronic processes that reflect these natural sound processes, and hydrophone recordings I made in the Amsterdam canals. I was looking at musical properties of sounds that may be outside our natural hearing range, or too fast for us to perceive. By slowing down and lowering pitches I built up a soundscape based on temporal, harmonic and dynamic qualities present in the underwater soundworld.
