Introduction: can clearly be seen that an anatomical and physiological pathways  in auditory system from Peripheral parts to auditory cortex in binaural hearing than monaural hearing  is not merely doubled, but with addition of a second ear, Communication between two ears from superior olive complex to auditory cortex is largely increased. In addition to the auditory pathway a numerous synapses with other sensory pathways, such as visual and somatic sensory established, that this interactions in comparison to monaural pathway significantly is further. The power and sensitivity of the auditory system increases with these synapses and reduce the error rate of it.

Discussion & Conclusion: Increase a synapses between auditory, visual and somatic sensory pathways eventually lead to an increased ability to perception and speech processing in noise and reverberation situation, decrease of error in localization,  Increase the loudness, perception and distinguish of weaker sounds, Better quality of sound, Less effort during the hearing and a greater sense of satisfaction. Because of these advantages, binaural prescription of hearing aid and other aided listening devices in hearing impaired patients are in priority.

Keywords: Binaural hearing, Localization, Speech perception in noise, Auditory satisfaction
