Procedure


  1. Select Loudness Scaling in the ribbon and click on New Measurement
  2. Select the machine and the test frequency (250, 500, 1000, 2000, 4000 or 6000 Hz) from the drop-down list
  3. You can choose to check the Run Short Test box to reduce the number of presentation levels and to save time
  4. Use the controls to select the side of the test ear and the conduction
  5. In the Training mode, you can set a presentation level and click Present.  Alternatively, you can check the Auto Scan box and click Scan to make Audiqueen present all intensities from soft to loud.
  6. In the  Test mode, Audiqueen presents the stimulus at different presentation levels and the patient should say how loud this feels.
  7. The Repeat button can be used to repeat the previous sound once more.
  8. 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 is the root mean square for all presentation levels of (the median response – the normal response). 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.



Where 

  • RI = the median response at presentation level I
  • N = the number of presentation levels
  • norm = the normal value for presentation level I
