(Leader: Colburn)
The experiments and models developed here seek to build physiological and psychoacoustical models that can account for the remarkable abilities of human subjects to perform the variety of tasks described in the previous two thrust areas. These include, for example, the exquisitely sensitive detection thresholds for changes in acoustic patterns, or the ability to organize complex acoustic spaces with multiple simultaneous sources and highly cluttered environments. These tasks are essential for the algorithms described in Thrust areas I and II and the acoustic applications considered in Thrust area V.
