Therefore it is essential to define normal ranges and accurate changes in the wave form of the ABR in children. This study was undertaken with the analysis of 243 ABR in children with normal otological, developmental, neurological...

Clin Exp Pediatr. 1986;29(10):1114-1129.   Published online October 31, 1986
Auditory Brainstem Response (ABR) has been found to be useful evaluating objective assessment of hearing thresholds, maturation of the brainstem and neurological disorders in the brainstem. Therefore it is essential to define normal ranges and accurate changes in the wave form of the ABR. This study was undertaken with the analysis of 137 ABR in premature infants in a newborn...
