Experience with the behavioral assessment of hearing sensitivity is reported for 211 babies and toddlers aged 6-24 months. The visually reinforced head-turn procedure, visual reinforcement audiometry (VRA), was utilized to obtain threshold estimates for infants evaluated for both research and clinical purposes. At the initial test session, 90% of the infants and toddlers provided useful audiometric threshold data for air-conducted tonal signals; 84% could be assessed using standard earphones. The equipment arrangement described allows a single audiologist to complete the VRA assessment. The behavioral test technique offers the clinician a simple, efficient procedure for the routine audiometric assessment of the vast majority of very young children.
