What is auditory perception? Some of the computational challenges/ Challenges? Separating out various background noises from what you actually want to hear. Often you need to know where the sounds are coming from. What: segregating the auditory scene Identifying auditory objects: sounds must be recognized across variability in the signal to identify: Specificity (what is specific to the object) Invariance (object constancy: what is shared with others). Where: Location must be computed because (unlike vision) it is not “given” by the geometry of the sensory surface. Sound: audible variations in air pressure (movements) if aur molecules; some of these variations are periodic Frequency: the number of compressed or rarefied patches of air molecules that pass by our ears with each sound: determines pitch Cycle: time between successive compressed patches Hertz: the number of cycles per second: human auditory system responds to 20-20,000 Hz
