PURPOSE: to describe the hearing findings of a family with autosome dominant hereditary hearing loss. METHODS: we evaluated 17 subjects. The evaluation was made by pure tone audiometry, Speech audiometry, tympanometry and acoustic reflex testing, in addition to genetic follow-up. RESULTS: from 17 evaluated subjects, 11 showed some degree of neurosensorial hearing loss (64.7%), being 8 female gender (73%) and 3 male gender (27%). The subject age varied from 5 to 68 years (average = 39.6) and the time from the complaint's appearance varied from 20 to 38 years. The hearing loss was modified with age. We did not find normal hearing after the age of 41 years in the family. CONCLUSION: the hearing investigation regarding all members of the family regardless of any complaint is extremely indispensable due to the existence of hearing loss even when limited to isolated frequencies.
