How to perform basic audiometry with Equinox Evo

By Interacoustics

This quick guide will focus on basic pure tone audiometry functions as well as a basic introduction to the various icons, tools and menus available.

 

 

Starting up the AC440 module

Launch the Equinox Suite from Noah, OtoAccess®, or standalone.

Click on the eight note icon to launch the tone audiometry screen if tone audiometry is not the default screen.

Select the desired audiometry protocol from the "Protocols and Sessions" drop down list.

 

Conducting pure tone audiometry

Choose the transducer type and the stimulus type.

The table below shows how to choose the test frequency and intensity, and how to present the stimuli.

 

Test frequency Intensity Stimuli presentation
PC keyboard Left/right arrow keys Up/down arrow keys Space bar or left ctrl
Mouse Left/right arrow buttons Up/down arrow buttons Hover over 'Stimuli'
Touch Keyboard Left/right arrow buttons Dials Use stimuli touch field

 

Masking

Turn on masking in Channel 2 by ensuring that the desired transducer is selected for the non-test ear.

Ensure that the word "Masking" is highlighted in orange.

Choose "Rev" to present the masking noise continuously.

It is also possible to turn on Automasking or Masking Help.

 

Navigation: Tools and functions

We'll cover tools and functions briefly. For a more detailed description of how to use the AUD440 module, please refer to the Instructions for Use and Additional Information documents.
