PSYC 102 Chapter Notes - Chapter 12: Interaural Time Difference, Sound Pressure, Auditory Scene Analysis
Document Summary
Auditory localization problem- how to tell where sounds are coming from. Problem of reflected sound- how we can hear things clearly without an echo even though they bounce off walls. Auditory scene analysis problem- how we can differentiate sounds are coming from different sources. Problem of metrical structure- how do we perceive a beat pattern. Auditory localization- process of locating sound sources in an auditory space. Cochlea doesn"t give/receive info about a sounds location (2 stimuli with same frequency will activate same area of cochlea even if they are in different locations) Use location cues to determine a sound"s location, which are created by the way the sound interacts with the listener"s head and ears. Sound"s position has three dimensions- azimuth (axis that extends left to right), elevation (extends up and down), and distance (how far sound source is away from listener.
