the correlation between binaural interaction component of the auditory brainstem response and total score of the persian version of the spatial hearing questionnaire

Background and aim: people with spatial hearing impairment have difficulty perceptionof speech in the presence of noise, sound localization, and estimating the distance from thesound source. in this study, the comparison between amplitude and latency of the binauralinteraction component of the auditory brainstem response (abr-bic) with the total score ofthe persian version of the spatial hearing questionnaire (shq) in adults with normal hearingand moderate sensorineural hearing loss (snhl) was evaluated.methods: in this cross-sectional comparative study 55, 18–45-year-old individuals including35 of normal hearing and 20 moderate snhl participated. all participants underwent theassessments of medical history, otoscopy, conventional audiometry, tympanometry, shqquestionnaire, and auditory brainstem response (abr).results: there was no significant correlation between the amplitude and latency of the abrbicand the persian version of the shq in normal groups (r=–0.085, r=0.116) and in moderatesnhl groups (r=0.030, r=0.119). the mean value of abr-bic range of people with normalhearing and snhl is statistically significant (p=0.001).conclusion: the results showed that the amplitude and latency of abr-bic were notcorrelated with the persian version of the shq in people with normal hearing and withmoderate snhl but statistically significant between the mean amplitude and latency of abrbicin people with normal hearing and people with hearing loss.
