Aim: the present study aimed at verifying the ability to detect pure tones of different frequencies by means of liminal tonal audiometries. Study design: clinical prospective randomized. Material and method: we studied 67 individuals with cerebral palsy who presented no complaints of hearing problems in order to discuss the etiologic factors likely to be responsible for the motorial sequelae. Results: Since the results have pointed to a high variability of hearing losses, the relationship of the factors pointed by the parents as responsible for the motorial deficits was reviewed, correlating them to the probable etiology of hearing loss.
