Background: neurosensory hypoacusis in the child produces serious consequences in language acquisition, important attribute to appropriate learning and social performance. Objective: to study the behavior of neurosensory hypoacusis in children at Camagüey's province. Method: a descriptive study on the behavior of neurosensory hypoacusis in children at Camagüey's province was accomplished, from January 2007 to December 2009. The universe was constituted by 250 hypacusic children and deaf persons, reported by the Center for diagnosis and guidance, the deaf persons and hypacusic school José María Heredia and the audiology consultation at the University Paediatric Hospital Eduardo Agramonte Piña. The application of the exclusion criteria determined a non-probabilistic sample of 83 children. The studied variables were age at which hearing impairment was detected, sex, etiology, uni- or bilateralism, amount of auditory dysfunction by preliminary audiometry, electroaudiometry and auditory potentials evoked of the brainstem. Results: there was no predominance in sex in the analysis of results; the age in which a greater number of patients were diagnosed was 0-5 years, in 43 patients. Severe hearing loss was the most diagnosed, in 31 cases and in the deep one, just five patients; fetal distress, low birth weight, ototoxic antimicrobials and Usher's syndrome were the most interrelated causes.  Fetal distress was the most frequent cause of bilateral hearing loss. Conclusions: neurosensory hypoacusis was frequent in the studied period.
