Electrical Evoked Stapedial Reflex Thresholds (eSRT) can be a very useful objective measure for the upper stimulus levels during the programming of a cochlear implant (Brickley et al., 2005; Buckler…
Standalone ESC vHIT includes a Spontaneous Nystagmus test where you can record eye movements before beginning your vHIT test protocols. Figure 1 - EyeSeeCam standalone default protocol If you purchas…
This paper discusses the mechanism of weighted averaging and in what circumstances it improves otoacoustic emission (OAE) measurements. It details investigations of OAE measurements on a wide range o…
It is relatively simple to track horizontal and vertical eye movements using videonystagmography (VNG) because they can be directly deduced from the position of the pupil. However, torsional movement…
What is the acoustic reflex? The acoustic reflex is the contraction of the stapedius muscle elicited by the presentation of an acoustically loud sound. When either ear is presented with a loud sound…

Before starting my position with Interacoustics, I used VisualEyes™ all day every day for several years in a busy vestibular clinic. Even though I felt like I knew the software well, transitioning to…
If you have purchased the VORTEQ™ Assessment or Functional Assessment bundle, you will be able to perform the Dynamic Visual Acuity (DVA) test. DVA is an assessment of the Vestibulo-Ocular Reflex (VO…
There are big differences between what people call virtual reality (VR) for persons with balance and vestibular disorders. Use of a head-mounted device, a CAVE (large scene that is not moveable from…
