Steady State Responses to Multiple Amplitude-Modulated Tones: An Optimized Method to Test Frequency-Specific Thresholds in Hearing-Impaired Children and Normal-Hearing Subjects

Abstract

The binaural MF SSR was proven to be a valid technique for the estimation of an objective audiogram, in a large sample of hearing-impaired children and normal-hearing subjects. With this method, frequency-specific thresholds at 0.5, 1, 2, and 4 kHz could be determined in all subjects (and both ears) with no appreciable loss in accuracy and a considerable reduction in testing time (average recording time = 21 minutes) when compared with other frequency-specific techniques.
