What are distortion product otoacoustic emissions (DPOAEs)? Distortion Product Otoacoustic Emissions (DPOAEs) are acoustic signals that can be detected in the ear canal of a person with normal outer…
This video introduces you to the Aided Cortical software module for Eclipse. Learn the basic navigation of the software. You can read the full transcript below. Transcript This is an introduction to…
The mono-thermal (“screening”) version of the caloric test refers to stimulating at one temperature on each ear. In many cases the results from two irrigations will be sufficient to inform the tester…
What is pure tone audiometry? Pure tone audiometry measures hearing sensitivity at various frequencies for air conduction and bone conduction. The test can specify the air conduction and bone conduct…
Required equipment Equinox Evo A patient response button Headphones or insert phones Test procedure Figure 1: SISI test screen. Open the AC440 and enter the SISI screen by selecting Menu | Tests | SI…
Computerized dynamic posturography (CDP) is a scientific framework for understanding the control of balance and postural stability. CDP can objectively quantify functional impairments and is ideal fo…
I have heard of the ‘Binaural Interaction Component’. What is this and how can it be measured using the Eclipse? Answer: The binaural interaction component (BIC) an evoked response used to probe the…
What is high frequency audiometry? High frequency audiometry (above 8 kHz) is performed using the same procedure as normal air conduction audiometry. High frequency audiometry is helpful when testing…
This video demonstrates 4 kHz NB CE-Chirp® ABR testing via bone conduction on a 4-week-old baby. Her air conduction (insert earphones) results at the same frequency indicated satisfactory hearing. Th…
About the author The information presented here is based on clinical examples as well as modeled patterns. Text and accompanying absorbance sketch is authored by Navid Shahnaz, PhD, Aud, Associate Pr…
Test procedure Launch the Equinox Suite from Noah, OtoAccess® or standalone. Click on the AUD tab on the upper right-hand side of the screen. Perform audiometry before the ANL test as this determines…
It is simply a band of noise that is focused is a very narrow band of frequencies, with steep filter slopes, to produce a noise stimulus suitable for threshold estimation. For example, this is a spec…
