Pediatric audiology has seen the inclusion of the auditory steady-state response (ASSR) in clinical test batteries as a valuable diagnostic tool. Its unique stimuli, recording and analysis characteristics allow for applications not previously possible with other auditory evoked responses in infants and young children. Although the long-standing research and clinical validation history of the frequency-specific auditory brain stem response (ABR) make it the current gold standard for estimating hearing thresholds, accumulating evidence is establishing the ASSR as a reliable and accurate tool for the diagnosis of hearing loss in infants. Current test-protocol efficiency and accuracy may be improved by including the ASSR to supplement ABR data and to cross-check test results. This article reviews the ASSR and its current clinical applications and limitations for determining hearing thresholds in infants and young children.
