Webwhen sound vibrations reaches the cochlear it will generate cocholear wave that will starts at the basil end and travels to the apical end along the basil membrane and that is called a traveling wave. The end connected to the middle ear ossicles is the basil end and the other end is the apical end. 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.
