Audiological findings on 94 rubella children with histories of prenatal rubella incurred during the epidemic of 1963 to 1964 are reported. These children represent the first group drawn from a population of over 600 whose hearing could be evaluated by conditioned pure-tone air and bone-conduction tests. A hearing loss of 26 dB or more (ISO 1964) in the better ear was found in 58.5% of the children tested. Thirty-eight percent were of profound degree. The most frequently encountered audiometric configuration was "flat" which occurred in 63.8% of the patients. Audiograms were characterized by three forms of symmetry: degree of hearing loss, type of hearing loss, and configurational classification. While the majority of losses (67%) were sensorineural, conductive components were found in 32.8% of the better ears of the testable children.
