The Cortical Automatic Threshold Estimation in Adults

Abstract

This article brings together the work we have been doing at the National Acoustic Laboratories (NAL) to make cortical threshold testing easy, fast, and accurate. Our aim is to improve techniques for estimating hearing thresholds on people who, for whatever reason, are unable to give reliable behavioural responses to indicate that they have heard a sound. The particular techniques described have general applicability to cortical testing, and have been evaluated within a practical package that will become part of the HEARLab family of test modules. Cortical testing nicely complements auditory brainstem testing both because it is best carried out while the patient is awake rather than asleep, a..
