Damage to one of the auditory coex causes?

No noticable deficit at all as there is overlap of coex REF: Integrative functions in the mammalian auditory pathway by Donata Oeel, Richard R. Fay, Ahur N. Popper page 32 Unilateral lesions to auditory coex result in deficits in localization of sounds presented in contralateral hemisphere. However gray's anatomy 39th" ed chapter 22 says Injury of the auditory coex in man produces a variety of manifestations, including coical deafness, verbal auditory agnosia and non-verbal auditory agnosia. The markedly bilateral nature of the auditory pathway means that noticeable deficits occur only when there is bilateral damage.
