Central auditory processing and listening effort in normal-hearing children: a pilot study

Abstract

Objectives

The current study aims to assess the link between central auditory processes and listening effort in a group of normal-hearing children. This will provide information over and beyond the standard central auditory processes and might have practical implications for listening situations which often require speech understanding in noisy environments.

Method

The current study included 35 normal-hearing children from six to eleven years old. Tympanometry, tonal audiometry, and speech audiometry was performed. Different auditory processing skills were assessed using the Frequency Pattern Test, the Staggered Spondaic Word Test, and the Dichotic Digits Test. Finally, a dual-task paradigm was used to evaluate listening effort. This paradigm consisted of the simultaneous performance of a speech-recognition task in different conditions of background noise and a visuospatial memory task using a digital Corsi Block test.

Results

Significant correlations between listening effort and several components of the auditory processing tests were established. Specifically, listening effort correlated significantly with some components of the SSWT as well as the DDT. Additionally, the listening effort test showed a significant age effect for the listening condition with the highest Signal-To-Noise Ratio.

Conclusions

Based on the current results, inclusion of listening effort in the test battery for auditory processing disorders would be valuable.
