Abstract

Purpose: The aim of this study is to investigate the age-related changes of the Contralateral Acoustic Reflex Suppression (CARS) test in individuals with normal hearing and to provide age-related normal values.

Method: The study included 66 individuals aged 18-65 years. The participants were divided into three age groups, respectively, 18-30 years, 31-45 years, and 46-65 years. Acoustic reflex threshold and acoustic reflex amplitude measurements were performed at frequencies of 500, 1000, and 2000 Hz in the presence and absence of suppressive noise from the contralateral ear.

Results: In the comparison of suppression amounts according to age groups, the highest suppression amount at all frequencies was observed in the 18-30 years age group.

Conclusions: It is known that changes in the function of the efferent hearing system occur due to aging. In the CARS test, a decrease in the amount of suppression produced by the efferent system has been observed due to aging.

评估年龄对听力正常者对侧声反射抑制测试的影响

目的：本研究旨在调查听力正常者的对侧声反射抑制（CARS）测试与年龄相关的变化，并提供与年龄相关的正常值：研究对象包括 66 名年龄在 18-65 岁之间的人。方法：研究对象包括 66 名 18-65 岁的人，他们被分为三个年龄组，分别是 18-30 岁、31-45 岁和 46-65 岁。在对侧耳有或没有抑制噪音的情况下，分别对 500、1000 和 2000 Hz 频率进行声反射阈值和声反射幅度测量：在根据年龄组进行的抑制量比较中，18-30 岁年龄组在所有频率下的抑制量最高：结论：众所周知，听觉传出系统的功能会随着年龄的增长而发生变化。在 CARS 测试中，可以观察到传出系统产生的抑制量会随着年龄的增长而减少。

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.
