All psychoacoustic tests (A§E tests and speech audiometry) can be performed in the Audiqueen test environment. The intensity will be controlled in Audiqueen with minimal adjustments to be performed on the audiometer device itself. For this purpose, Audiqueen gives instructions to the users on when and how they should adjust the audiometer output. Audiqueen will ask to put the audiometer output to two possible intensities.  

To have a generic audiometer work with our Audiqueen test environment, every transducer that is used with the audiometer should reach 90 dB SPL !!

Example of the two possible instructions Audiqueen will give to the audiologist during testing.

The audiometer's AUX channel must be correctly calibrated by the manufacturer! 
If not, please contact your audiometer supplier to calibrate your device. 

The connection between Audiqueen and the audiometer needs to be calibrated.  This is how you proceed:

For Speech Audiometry, select Otoconsult’s built-in
‘(Speech) Audiometric Module’ in the Software selector of the Format window.

For all other psychoacoustic tests, this module is automatically selected.

After clicking on New Measurement, 

select Audiometer (1) and proceed to calibration (2).

The calibration comprises 2 steps: (1) select the transducers and channels and (2) play a calibration signal and adjust the appropriate levels.

Click on the number in the header to select the first or second calibration step.

The first step is to select the soundcard and the transducers that you wish to have available for testing. 

The second step comprises calibration of the speech input channel of your audiometer. The verification button is to double-check the calibration of the total audio chain.

The recommended approach with a calibrated audiometer is to play the calibration signal and adjust the input sensitivity of the audiometer until the VU meter shows a 0 dB offset. The VU meter and an adjustment button should be available on the audiometer or in its software suite.

In the unlikely case that you prefer not to modify the input sensitivity (this may be the case if other external devices need to connect to the same aux-input), check this box and adjust the slider until the VU meter shows 0 dB offset or click the AutoAdjust button and let Audiqueen set it for you.

Please bear in mind that this will attenuate the A§E sounds and reduce the intensity dynamic range. Reducing it too far will cause the usability to drop from optimal to suboptimal, just acceptable and ultimately unacceptable. This is indicated by the message (circle) at the bottom.

The system is correctly calibrated for Audiqueen if (1) the speech channel output of your audiometer is correctly calibrated and (2) the VU meter deviates to zero when playing the calibration sine. Click on the ‘run verification’ button to double-check the calibration of the entire audio chain. Audiqueen will play three sounds at different intensities. With a sound level meter placed near the patient’s head, the user can measure the intensity in dB SPL and enter each reading.

If Audiqueen does not confirm the correct calibration, please contact your audiometer manufacturer or supplier for a calibration check.

Important information for audiometers that are NOT calibrated in dB SPL, but rather in dB HL !!!

Audiometers are either calibrated in a dB HL or dB SPL scale for speech signals.

My audiometer is calibrated in a dB SPL scale

By default, Audiqueen is designed to present speech in a dB SPL scale. Therefore, no further actions are needed to make Audiqueen compliant with your audiometer device. The default intensity at which your audiometer output intensity should be set is 70 dB SPL. For louder stimulation (extended range), Audiqueen will ask you to put your audiometer to 90 dB SPL.

We believe it is good practice to present speech signals in dB SPL. The reason for this is that Audiqueen offers the possibility to have multiple speech tests, which can have slightly different RETSPL values depending on the language and difficulty of the test. If possible, ask your audiometer manufacturer or supplier to calibrate your device in dB SPL for speech signals.

My audiometer is calibrated in a dB HL scale

To make Audiqueen and its instructions to the user compliant with the dB HL scale of your audiometer, please perform the following steps:

  • Go to the speech audiometry environment and click on ‘New Measurement’.
  • Open the ‘Speech Audiometry Settings’ by clicking on the icon in the top-left corner.
  • Click on the checkbox to present speech in a dB HL(!) scale and add the correct HL-to-SPL offset which is used by your audiometer device. Then press OK.

This will change the intensity presentation to a dB HL(!) scale in speech and speech-in-noise audiometry. Moreover, the instructions that Audiqueen gives to the user will also be modified to that scale.

Please note that the intensity scale only changes in the speech and speech-in-noise audiometry module. However, the instructions that Audiqueen provides for your audiometer will be adjusted for the dB HL scale of your device across all tests. 

 The audiometer output settings as requested by Audiqueen can be  

monitored during testing by hovering over the blue information icon.
