Abstract
Purpose: The binaural interaction component (BIC) is presumed to reflect binaural hearing abilities, including spatial hearing. This study aims to record BIC amplitudes and examine their relationship with behavioral auditory tests.Methods: Nine elderly adults with hearing loss (eight males and one female) participated in this study. The BIC was derived from the wave V amplitude of the auditory brainstem response (ABR) and the N1-P2 amplitude of the auditory late latency response (ALR). Behavioral auditory processing tests, including sentence recognition scores, localization scores, and masking level difference, were obtained and analyzed with respect to electrophysiological BICs.Results: BICs were more reliably identified in ALR compared to ABR. The ALR BIC elicited by a 2,000 Hz tone burst showed a significant correlation with sentence recognition scores in both quiet and noise, as well as localization scores at 2,000 Hz. Other variables also demonstrated significant interrelationships.Conclusion: This study suggests that the ALR BIC elicited by a 2,000 Hz tone burst may be a key physiological component representing spatial hearing abilities in individuals with hearing loss. More robust conclusions can be drawn from future studies with larger sample sizes and more sophisticated designs.
