⚠ Important Note: Some thresholds will be unknown. If thresholds are unknown, you can use MATs (Masking Assumption Thresholds) which will be used in masking calculations but won't show in results tables. Enter several likely values; if in doubt use the level resulting in higher noise. If hearing is within normal limits, you may need to edit the MATs based on the clinical picture.
