Auditory system comparisons between sand cats and other felid species : acoustic input admittance of ears and auditory brainstem responses
… acoustic power absorption, and thresholds of auditory- brainstem responses. In a zoo, measurements were made in 37 ears of 23 anesthetized specimens, including sand cats and five other felid species. Sand cats have lower mean thresholds at frequencies between 0.25 and 5 kHz by 6-9 dB than …

Towards a neurophysiological correlate of the precedence effect: from psychoacoustics to electroencephalography
… shed light on the question on which stage of the auditory pathway information related to the precedence effect is processed. Investigations were made by means of psychoacoustics and auditory evoked potentials (AEPs). Elaborate preparative psychoacoustical measurements were performed in order to …

Accuracy of 40-Hz Automated and Sinusoidal ASSR and Tone-Burst ABR Thresholds in Normal-Hearing Adults Using Kalman-Weighted Filtering
Auditory brainstem responses (ABR) and auditory steady state responses (ASSR) are useful for estimating hearing in difficult-to-test populations. For these populations, Kalman-weighted filtering and in-situ pre-amplification can be advantageous for ABR recordings, but little is known about the …

Neural abnormalities underlying tinnitus and hyperacusis
… functional magnetic resonance imaging (fMRI) and auditory brainstem responses (ABRs) to measure sound-evoked activity in the auditory pathway. Subjects with clinically normal hearing thresholds, with and without tinnitus, underwent fMRI or ABR testing and behavioral assessment of sound-level …

The Audiometric Profile of Young Adults Who Report Difficulty with Speech Perception in Noise
… product otoacoustic emissions (DPOAEs), and auditory brainstem responses (ABR) in 13 participants (5 with reported difficulty in noise & 8 controls). Participants who reported difficulty in noise rated their speech perception in noise performance as poorer on the SSQ, performed within normal …

Hear Today, Gone Tomorrow: Exploring Quinoxaline Derivatives as a Treatment for Noise-Induced Hearing Loss
… Their therapeutic effects were quantified using auditory brainstem responses (ABR), distortion product otoacoustic emissions (DPOAE), and morphological analysis. The derivatives’ bioavailability was assessed using an in silico ADME assay from SwissADME. A kinome activity assay was performed on …

Slow modulation of cochlear response by the olivocochlear efferent system elicited by sustained noise or threshold elevation in the contralateral ear
… of mice by repeatedly measuring bilateral auditory brainstem responses (ABR) and "DPOAE growth functions across a wide range of frequencies and levels for periods of about 1-2 months. About halfway through the period, a unilateral reduction in neural output was created, either by acoustic …

ORAL ADMINISTRATION OF EPIGALLOCATECHIN-3-GALLATE (EGCG) IS A POTENTIAL THERAPEUTIC FOR CISPLATIN-INDUCED HEARING LOSS
… cisplatin-induced hearing loss, assessed by auditory brainstem responses. These changes were associated with a reduction in cisplatin-induced loss of OHCs primarily in the basal region of the cochlea, along with reduced oxidative stress, inflammatory and apoptotic markers. In addition, EGCG …

Effects of Aging and Spectral Shaping on the Sub-cortical (Brainstem) Differentiation of Contrastive Stop Consonants
… the influence of aging on the sub-cortical (brainstem) differentiation of voiced stop consonants (i.e. /b-d-g/); (2) determine whether potential aging deficits at the brainstem level influence behavioral identification of the /b-d-g/ stimuli, (3) investigate whether spectral shaping …

Effects of Developmental Exposure to Environmental Contaminants on the Auditory System
… of neurotoxic effects, including long-term auditory deficits. We assessed auditory function in adult rats developmentally exposed to a unique PCB mixture formulated to model the congener profile of PCBs found in fish consumed by a human population in northeastern Wisconsin. Measurements of …

Hörschwellenmessung mit Zeitgang-BERA, Standard-BERA und konventioneller Tonaudiometrie - eine Vergleichsstudie
… des Auftretens von Muskelartefakten bzw. „PAM responses“ zeigte, dass diese die reine Hörschwellenermittlung nicht signifikant beeinflussen, unabhängig davon, ob sie nur in den lauten Pegeln (ab 60 dB) auftreten oder bis zur Hörschwelle vorhanden sind und bestätigten die in der Literatur …
