WebJan 27, 2024 · The human brain is finely tuned not only to recognize particular sounds, but also to determine which direction they came from. By comparing differences in sounds … Sound localization is the process of determining the location of a sound source. The brain utilizes subtle differences in intensity, spectral, and timing cues to allow us to localize sound sources. In this section, to more deeply understand the human auditory mechanism, we will briefly discuss about human ear localization theory. WebSound localization is only moderately more precise when the listener points directly toward the source. The process is not analogous to localizing a visual source on the fovea of the retina. Thus, head motion provides only a moderate increase in localization accuracy. great is your love for me
