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. Ensure that your audiometry has been performed ahead of advancing into the SIQ test as this determines the starting level for the test.

Click on Menu, Tests, and then select SIQ.

 

Figure 1: Selecting SIQ.

 

Once on the SIQ test screen, the stimuli levels should be set for you. These are based on the patient’s audiogram and the PTA score.

 

At the top it is possible for channels 1 and 2 to: Change the output, change the input, alter the level, or present the stimulus. In the middle the calculated SRT and SNR are displayed, below which the user can press a tick button or cross button to score responses. Based on the patient’s pure tone audiogram and with a pure tone average of 35 dB, the initial stimulus level is set to 35 dB.

Ensure that your speech material is correct, and the relevant list has been chosen.

Instruct the patient to respond by repeating the words that they hear. Press the play icon to begin the test.

On the patient’s response, score the words correct or incorrect according to their response. The system will automatically increase the next stimulus intensity for an incorrect response and decrease the next stimulus intensity for a correct response.

Repeat this procedure until your word list has been completed. The system will automatically store on the completion of your word list.
