Mental tasking and rotary Chair-Induced vestibular nystagmus utilizing Video-Oculography.

To investigate whether the use of mental tasking, when compared to no mental task, affects measurement of nystagmus response with regard to gain, phase & symmetry, and artefact when utilising video-oculography (VOG) as the measurement technique in rotary chair testing (RCT). A within-subject repeated-measures design was utilised. Seventeen (17) healthy adults were evaluated (age 22-25 years).

Relationship Between Auditory and Visual Noise Acceptance in Normal-Hearing Listeners.

Background: Research has shown that hearing aid acceptance is closely related to how well an individual tolerates background noise, regardless of improved speech understanding in background noise. The acceptable noise level (ANL) test was developed to quantify background noise acceptance. The ANL test measures a listener's willingness to listen to speech in noise rather than their ability to understand speech in noise, and is clinically valuable as a predictor of hearing aid success.

Mental Tasking and Caloric-Induced Vestibular Nystagmus Utilizing Videonystagmography.

Purpose: The purpose of this study was to quantify the effects of mental tasking on measures of the caloric vestibulo-ocular reflex utilizing videonystagmography as the measurement technique.

Method: A within-subjects repeated-measures design was utilized. Sixteen healthy adults were evaluated (13 women, 3 men; ages 19-31 years).
