- You can choose to check the Run Short Test box to reduce the number of presentation levels and to save time

- In the Test mode, Audiqueen presents the stimulus at different presentation levels and the patient should say how loud this feels.
- The Repeat button can be used to repeat the previous sound once more.
- After the last presentation, Audiqueen calculates the median scores per presentation level and a global score expressed as RMS value.
Audiqueen calculates the RMS value as a measure of the error compared to the normal line. This RMS (root mean square) is the root of the sum of (the median response – the normal response) for all intensities (presentation levels). As such, this is a positive value. Audiqueen adds a sign mark. This is the sign mark of the sum of all responses – the sum of all normal responses.
