Abstract
Purpose: This preliminary study aimed to examine spatial auditory perception and selected cognitive functions in individuals with unilateral peripheral vestibular disorders and clinically normal hearing.
Method: Fifteen individuals with unilateral peripheral vestibular disorders and 18 age-matched healthy controls underwent audiological and cognitive assessments. Spatial hearing was evaluated, and cognitive performance was assessed to account for its potential influence on spatial hearing.
Results: Exploratory analyses showed poorer spatial hearing performance in the vestibular group than in the control group. After adjustment for age and pure-tone average, significant group differences remained under the spatially separated condition (SV90) and for spatial advantage, whereas the difference under the co-located condition (SV0) was no longer statistically significant. Although tinnitus prevalence differed between groups, within-group analyses showed no significant association between tinnitus and spatial hearing performance. No statistically significant group differences were observed in cognitive performance.
Conclusions: Unilateral peripheral vestibular dysfunction was associated with poorer spatial auditory performance, particularly under spatially separated listening conditions and in spatial advantage. Overall, the findings suggest that unilateral peripheral vestibular dysfunction may influence spatial hearing despite clinically normal hearing.
期刊介绍：
Mission: AJA publishes peer-reviewed research and other scholarly articles pertaining to clinical audiology methods and issues, and serves as an outlet for discussion of related professional and educational issues and ideas. The journal is an international outlet for research on clinical research pertaining to screening, diagnosis, management and outcomes of hearing and balance disorders as well as the etiologies and characteristics of these disorders. The clinical orientation of the journal allows for the publication of reports on audiology as implemented nationally and internationally, including novel clinical procedures, approaches, and cases. AJA seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work.
Scope: The broad field of clinical audiology, including audiologic/aural rehabilitation; balance and balance disorders; cultural and linguistic diversity; detection, diagnosis, prevention, habilitation, rehabilitation, and monitoring of hearing loss; hearing aids, cochlear implants, and hearing-assistive technology; hearing disorders; lifespan perspectives on auditory function; speech perception; and tinnitus.
