Recently, auditory steady-state responses (ASSRs) have been proposed as an alternative to the auditory brainstem response (ABR) for threshold estimation. The goal of this study was to investigate the degree to which ASSR thresholds correlate with ABR thresholds for a group of sedated children with a range of hearing losses. Thirty-two children from the University of Iowa Hospitals and Clinics ranging in age from 2 months to 3 years and presenting with a range of ABR thresholds participated. Strong correlations were found between the 2000-Hz ASSR thresholds and click ABR thresholds (r = .96), the average of the 2000- and 4000-Hz ASSR thresholds and click ABR thresholds (r = .97), and the 500-Hz ASSR and 500-Hz toneburst ABR thresholds (r = .86). Additionally, it was possible to measure ASSR thresholds for several children with hearing loss that was great enough to result in no ABR at the limits of the equipment. The results of this study indicate that the ASSR may provide a reasonable alternative to the ABR for estimating audiometric thresholds in very young children.

Objectives: Deletion of gene in mice has been linked to progressive hearing loss and degeneration of cochlear cells. Cisplatin, an antitumor drug, can cause various side effects, including ototoxicity. The aim of this study was to investigate the effects of on cisplatin-induced hearing impairment in mice and to explore the possible mechanism.

Objective: This study assessed the relevance of auditory brainstem response (ABR) thresholds in evaluating cochlear implantation (CI) candidacy by studying their correlation with functional hearing in patients with sensorineural hearing loss (SNHL).
Design And Study Sample: In this retrospective study, we examined correlations between ABR thresholds, speech perception scores in quiet and pure-tone audiometry in 191 adults. We compared these correlations between individuals with different degrees of SNHL to discern differences in potential CI candidates and individual with less severe SNHL.

The genus has been extensively used as a model for ecological, behavioral, and evolutionary investigations. We used auditory brainstem responses (ABRs), craniofacial morphology, and pinna measurements to compare characteristics that impact hearing in two wild-caught species, . We observed significant statistical differences in craniofacial and pinna attributes between species with overall exhibiting larger features than .
