Objective: The aim of this study was to determine the relation between the acceptable noise level (ANL) and cognitive measures of auditory attention and working memory.
Design: Young adults were administered the following tests: the ANL, the Digit Span and Letter-Number Sequencing subtests of the Wechsler Adult Intelligence Scale-Fourth Edition, the Auditory Attention subtest from the Woodcock-Johnson Tests of Cognitive Abilities, the Hearing in Noise Test (HINT), and the operation span (OSPAN) test. A correlation matrix was constructed using Pearson coefficients.
Study sample: Twenty-four young adults aged 20-29 years with normal hearing participated in the study.
Results: No significant relationships were found among the ANL and the different cognitive tasks, nor was there a significant relation found between the ANL and the HINT. However, significant relationships were found between individual cognitive tasks. There was a significant relation found between selective attention and the most comfortable level of presentation of a story.
Conclusion: Selective attention may be a key cognitive function in acceptance of background noise.
