Description of the simulated protocols for the left ear
| Protocols | Stimulus level | Pass/fail criteria | True-positives (TP) | True negatives (TN) | Specificity | Sensitivity |
|---|---|---|---|---|---|---|
| Protocol 1 | 50 dB SPL | 1,000 Hz, 2,000 Hz, 4,000 Hz present | 45 | 14 | 100% | 97% |
| Protocol 2 | 40 dB SPL | 1,000 Hz, 2,000 Hz, 4,000 Hz present | 38 | 14 | 100% | 83% |
| Protocol 3 | 30 dB SPL | 1,000 Hz, 2,000 Hz, 4,000 Hz present | 21 | 14 | 100% | 46% |
(1 to 3: first column), stimulus level (second column), and pass-fail criteria (third column). The fourth column shows the calculated true negatives in the 46 ears with normal hearing thresholds. Column 5 shows the true-positive results in the 14 ears with moderate to profound hearing loss. Columns 6 and 7 show the sensitivity and specificity results. The Objective Response Detection (ORD) technique was MSC.
