At the 1989 meeting of the Triological Society in San Francisco, Calif, Drs Peter W. Alberti, Martyn L. Hyde, and Krista Riko, Toronto, Canada, presented a study regarding the validity of brain-stem audiometry in high-risk infants. The study group consisted of 731 high-risk infants comparing early brain-stem audiometry with results of later behavioral testing done at ages 3 to 5 years. Children were initially selected for evaluation from a high-risk registry and underwent brain-stem electric response audiometry at 3 to 4 months of age. Approximately 5% had moderate-to-severe hearing losses. The infants who had conductive losses due to middle ear effusion were excluded from the study. When a threshold for sensorineural loss of 40 dB or worse was utilized, brain-stem electric response audiometry was 94% sensitive, with a 96% specificity. For lesser degrees of hearing loss, the testing was considerably less sensitive, and the authors recommend that the 40-dB criterion
