the above photo shows the setup for a small sound installation i set up last month at university. the two speakers played a sound piece, composed of sine waves. One speaker channel had the signal inverted, playing the mathamatical opposite of it's partner. In theory this would create a region equidistant between the speakers where the waves would cancel each other out and tehre would be no sound. Onlookers were invited to suggest where they thaught the silent region was located on the white board provided. In practice, the region wasnt silent, but was distinctly quieter than its surroundings. I will hopefully reproduce this on a grander scale if i get the chance...
edit- when i manage to uplaod audio onto this thing i'll be able to post the sound recording i used...
