title: Simultaneous four-channel electric-response audiometry results in 8 years of hearing evaluation among small children.
abstract: The results of 8 years' experience with slow cortical-evoked responses obtained by a four-channel method are reported. The conclusion is that, even in this form, ERA is not a reliable tool for diagnosing hearing defects in children. The time course of the mean ERA threshold of 138 children examined in Turku University for periods ranging from 6 months to over 3 years is presented. The results are discussed. Electrocochleography or brain stem audiometry is recommended for clinical use.
