Abstract

Background and objectives: : This study was performed to comprehensively examine the amplitudes of the binaural interaction components (BICs) elicited by chirps, clicks, and 500 Hz tone-burst stimuli in individuals with normal hearing. Electrophysiological evidence of BICs was obtained and assessed for correlations with interaural time difference (ITD) and interaural level difference (ILD).

Subjects and methods: : Sixteen adults (4 males and 12 females) with normal hearing participated in this study. Auditory brainstem responses (ABRs) to chirp, click, and 500 Hz tone-burst stimuli were recorded, and BICs were derived based on wave V. The behavioral thresholds of ITDs and ILDs across multiple frequencies were obtained and analyzed.

Results: : BICs were found in most participants, regardless of stimulus type. The amplitudes of BICs elicited by chirps were the highest, followed by those elicited by clicks and 500 Hz tone-bursts. A significant correlation was found between the amplitudes of chirp-evoked BICs and the thresholds of 500 Hz ITDs and ILDs.

Conclusions: :This study found that chirp stimuli may be effective in eliciting BIC and predicting behavioral binaural interaction processing at low frequencies.

期刊介绍： Journal of Audiology and Otology (JAO) (formerly known as Korean Journal of Audiology) aims to publish the most advanced findings for all aspects of the auditory and vestibular system and diseases of the ear using state-of-the-art techniques and analyses. The journal covers recent trends related to the topics of audiology, otology, and neurotology conducted by professionals, with the goal of providing better possible treatment to people of all ages, from infants to the elderly, who suffer from auditory and/or vestibular disorders and thus, improving their quality of life. This journal encourages the submission of review papers about current professional issues, research papers presenting a scientific base and clinical application, and case papers with unique reports or clinical trials. We also invite letters to the editor and papers related to the manufacture and distribution of medical devices. This journal provides integrated views from otologists, audiologists, and other healthcare practitioners, offering readers high quality scientific and clinical information. This peer-reviewed and open access journal has been the official journal of the Korean Audiological Society since 1997 and of both the Korean Audiological Society and the Korean Otological Society since 2017. It is published in English four times a year in January, April, July, and October.
