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

Table 2 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.
