EARSHOT will experiment with ultra-sonic sound technology. This high frequency will be transmitted from the relative safety of a hired van at various sites across Berlin. Visitors or spectators may only notice the effect of Mitchell's sound work rather than hearing it for themselves as it is not pitched towards any human visitors. Results are not known, but these ultra-sonic frequencies have the ability to penetrate solid matter, supply focused energy and rouse the animal kingdom. It is very possible that something will happen, September 16. From the HIRSCHFELD exhibition release.
