Setup
- Turn on power (top-right button on the back of the unit) and the display should appear.
- Make sure the audio cable isn't plugged into anything, touch the display twice to move to the calibration screen.
- During the calibration absolute silence is necessary, no scanner noise, and no audio.
- If calibration is successful, a green checkmark will appear next to the Left and Right calibration boxes.
- Once calibrated successfully, touch the ANC button in the upper right-hand corner of the screen.
- Start your calibration or "learning" sequence.
- This sequence should be run before the task sequence and allows the noise cancellation algorithm to learn the noise coming from the scanner.
- If the audio cable is plugged in, make sure no audio is being played or else the learning will fail.
- The learning sequence should be at least 30 seconds long and should be the same exact sequence type being used for your fMRI tasks.
- Once the learning phase is complete, there should be a significant decrease in the scanner noise heard by the participant.
