Ipsilateral and contralateral acoustic reflex
WebThe acoustic reflex threshold (ART) is the sound pressure level (SPL) from which a sound stimulus with a given frequency will trigger the acoustic reflex. The ART is a function of … WebBoth contralateral and ipsilateral acoustic reflex thresholds were involved when subjects showed abnormal reflex thresholds. Although a high percentage of abnormal acoustic …

WebIpsilateral and contralateral acoustic reflexes were studied in neonates using 220 and 660 Hz probe tones and 500, 1000, 2000, and 4000 Hz activators. Activator sound pressure level was measured in all ears. Ipsilateral and contralateral reflexes were detected three times more frequently with a 660 Hz probe tone than with a 220 Hz probe tone. WebDiagram of acoustic reflexes with ipsilateral (I) and contralateral (C) stimulations of a patient with normal hearing. The reflexes are negative (upward) at all frequencies (0.5-3 …

In order to examine the function of the stapedius muscle in diseased ears, the recording of the stapedial electromyogram by an electrocochleographic (ECoG) method was considered. The SR was recorded simultaneously by the impedance method …
WebApr 17, 2024 · It might be expected that using AC will involve some cross-talk to ipsilateral IOM in oVEMP as subject 3 had same threshold for both contralateral and ipsilateral stimulation at 250 Hz, and all subjects had almost the same threshold at 500 Hz (this cross-talk is not shown in Figure 6).
