Changing fine structure constant, packing spheres tighter, and mimicking complex birdsongs
Date:11/4/2011

s from the design of the physical device? New research delves into the song the Zebra finch to test the hypothesis that much of its acoustic complexity is due to the nonlinear nature of the avian vocal organ. A version of the song created with simple numerical model, and compared with direct measurements of the physiological parameters driving the vocal organ, shows that simple instructions can closely mimic the peculiar and acoustically rich song of the Zebra finch. The research suggests that the design of a bird's vocal instrument is crucial to creating distinctive birdsongs, in much the same way that identical notes played on a piano and violin sound very different.
