Certain audiometers, called ‘supported audiometers’, allow to be ‘controlled’ by an external party such as Audiqueen. In that case, Audiqueen sends the commands to the audiometer and it feels like you are performing audiometry without even leaving the application. This is also the case for all other psychoacoustic tests. Examples of such audiometers are Madsen Aurical, Interacoustics Affinity and MedRX Avant. In case your audiometer is not in this list, you may follow the instructions for connected or generic machines. It is assumed that the audiometer output for speech and tonal audiometry is already correctly calibrated before the usage of Audiqueen. If not, please contact your audiometer supplier to calibrate your device.
The connection between Audiqueen and these supported audiometers needs to be calibrated. This is how you proceed:
Select Otoconsult’s built-in
Now the audio device must be selected and calibrated for each test.
For each test, after ‘New Measurement’ , select the audio device (1) and proceed to calibration (2).
The calibration for all audio devices 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 0 dB offset. For supported audiometers, Audiqueen displays the VU meters on screen.
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 inacceptable. 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 correct calibration, please contact your audiometer manufacturer or supplier for a calibration check.|
