This is how to use the sound field analyzer in the Eclipse Aided Cortical module.
Changes in the test room can affect the stimulus intensity of the aided cortical test.
The sound field analyzer compensates for this, ensuring the patient always receives the correct stimulus intensity.
We recommend running the sound field analyzer before each aided cortical test you perform.
To use the sound field analyzer, first open the Aided Cortical module.
Place the ambient microphone where the patient will sit.
The microphone should be level with the patient's ear.
Click ‘Sound field analysis’ in the menu on the left.
Press ‘Analyze sound field’ in the software.
The speaker will now play a pink noise signal, and the software will measure the intensity of each stimulus compared to the calibrated target.
Let the noise signal run for a few seconds, then press ‘Analyze sound field’ again to stop the noise presentation.
If results do not match the calibrated target as seen here, you can press ‘adjust to target’.
This will adjust the stimuli to match the calibrated levels.
Press ‘OK’ to save your sound field analysis.
The adjusted value is also shown on the report.
If you want to use a saved sound field analysis, click the dropdown menu and choose the saved sound field analysis.
Adjust to that target and press okay to save.
This feature is useful when the equipment is frequently moved between different locations.
