The Effect of Masking on the Acoustic Reflex Threshold
… of masking noise on the threshold for stapedial reflex. It has been shown that masking which shifts the hearing threshold causes a loudness function typical of recruitment. It was hypothesized that the stapedial reflex threshold remains the same in a masked situation as in the unmasked situation …

Development of 90th Percentile Norms for Ipsilateral Acoustic Reflex Thresholds: A Feasibility Study
<p>The acoustic reflex threshold has been well established in the literature as an involuntary bilateral contraction of the stapedius muscle in response to loud transient sounds. Additionally, the clinical utility of the acoustic reflex threshold has been established as it allows for the …

A preliminary study on the effect of selective serotonin reuptake inhibitors on peripheral and lower brainstem auditory processing.
… measures used were pure tone averages (PTA), acoustic reflex thresholds, uncomfortable loudness levels (UCL), otoacoustic emissions, masking level difference, temporal integration, amplitude resolution, and Beck Depression Inventory-II (BDI-II) scores. Results indicated that there was a …

The Effects of Selective Serotonin Reuptake Inhibitors (Ssri) on Auditory Measures in Clinically Depressed Subjects.
… included pure tone audiometry, tympanometry, acoustic reflex thresholds, and auditory electrophysiologic measures such as auditory brainstem and auditory late responses. An assessment scale for depression (Beck Depression Inventory-II) was also used. Results indicated statistically significant …

Frequency specificity of contralateral, ipsilateral and bilateral medial olivocochlear acoustic reflexes in humans
… the tuning properties of the human MOC acoustic reflex at different cochlear frequency regions and with different MOC-elicitor lateralities and frequency contents. Effects produced by the MOC reflex were quantified by the magnitude of the induced changes in stimulus frequency otoacoustic …

Objective audiological diagnostics using novel acoustical and electrophysiological tests
… alternative Methode zur Messung des Stapediusreflexes in Verbindung mit einer neuen, robusten Auswertemethodik eine signifikante Reduzierung des notwendigen Stimuluspegels bei gleichzeitig erhöhter Detektionsrate erlaubt. Die gleiche Methode wurde verwendet um eine Beziehung zwischen der …
