Feasibility and Repeatability of an Abbreviated Auditory Perceptual and Cognitive Test Battery.

Abstract

Purpose: Auditory perceptual and cognitive tasks can be useful as a long-term goal in guiding rehabilitation and intervention strategies in audiology clinics that mostly operate at a faster pace and on strict timelines. The rationale of this study was to assess test-retest reliability of an abbreviated test battery and evaluate age-related auditory perceptual and cognitive effects on these measures.

Method: Experiment 1 evaluated the test-retest repeatability of an abbreviated test battery and its use in an adverse listening environment. Ten participants performed two visits, each including four conditions: quiet, background noise, external noise, and background mixed with external noise. In Experiment 2, both auditory perceptual and cognitive assessments were collected from younger adults with normal hearing and older adults with and without hearing loss. The full test battery included measures of frequency selectivity, temporal fine structure and envelope processing, spectrotemporal and spatial processing and cognition, and an external measure of tolerance to background noise.

Results: Results from Experiment 1 showed good test-retest repeatability and nonsignificant effects from background or external noise. In Experiment 2, effects of age and hearing loss were shown across auditory perceptual and cognitive measures, except in measures of temporal envelope perception and tolerance to background noise.

Conclusions: These data support the use of an abbreviated test battery in relatively uncontrolled listening environments such as clinic waiting rooms. With an efficient test battery, perceptual and cognitive deficits can be assessed with minimal resources and little clinician involvement due to the automated nature of the test and the use of consumer-grade technology.
