1Two Difficult Problems for the Auditory SystemDetermining source location:The sound waveforms at the ears are one dimensional, making estimation of the direction and distance of the source very difficult. Performing source separation: Sounds from a given source often appear in a complex and varying context of other sources, making separation and recognition of sound sources difficult.These problems are responsible for much of the complexity in the design of the auditory system.

2Source Location and SeparationThe sound that reaches the ear is a combination of all the sound sources created in the environment. Thus, it is difficult identify the sounds that come from the different sources.
