Abstract

Objective

the present study aimed to investigate the applicability and feasibility of a new paradigm for assessing sound lateralization behavior.

Design

The Click Ordering Lateralization Test comprises two tracks (tracks 1 and 2), with 54 trials each. Each trial consists of one of nine intervals ranging from 0 to 230 ms between two noise bursts, whereby subjects must indicate on which side they first heard the noise. The COLT procedure was applied to 30 normal-hearing children (between 8 and 14 years old).

Results

the results indicated that an interaural time difference (ITD) of 0 ms functions as a control item, and after an ITD of 170 ms, the lateralization threshold reaches a ceiling effect. Different analysis methods were investigated in this study, with the total percentage score and a lateralization threshold of 5 hits deemed the most reliable methods. No differences were observed between test tracks and performance across the tracks was shown to be reliable and equivalent.

Conclusions

there are few procedures available to assess sound laterization in a clinical setting. This study presents the COLT as an easy-to-apply, reliable test for use in children aged between 8 and 14 years old.

期刊介绍： The purpose of the International Journal of Pediatric Otorhinolaryngology is to concentrate and disseminate information concerning prevention, cure and care of otorhinolaryngological disorders in infants and children due to developmental, degenerative, infectious, neoplastic, traumatic, social, psychiatric and economic causes. The Journal provides a medium for clinical and basic contributions in all of the areas of pediatric otorhinolaryngology. This includes medical and surgical otology, bronchoesophagology, laryngology, rhinology, diseases of the head and neck, and disorders of communication, including voice, speech and language disorders.
