PSYC2274 Chapter Notes - Chapter 10: Sound Localization, Interaural Time Difference, Sound Intensity
Document Summary
In this chapter, we get outside the head to investigate how hearing helps us learn about the real world. Having two ears is crucial for determining auditory locations. For most positions in space, the sound source will be closer to one ear than to the other. First, the pressure waves do not arrive at both ears at the same time. Sounds arrive sooner at the ear closer to the source. Second, the intensity of a sound is greater at the ear closer to the source. Interaural time difference interaural time difference (itd) the difference in time between a sound arriving at one ear versus the other. We can tell whether a sound is coming from our right or left by determining which ear receives the sound first. Azimuth > angle of a sound source on the horizontal plane relative to a point in the center of the head between the ears.
