Table 2 Description of the simulated protocols for the left ear

From: Auditory steady-state responses in school-aged children: a pilot study

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. (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.
